+
+        * keyboard.c (menu_bar_items): Bind Qinhibit_quit to Qt while we

+1993-05-26  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)

+
+        * s/aix3-2.h (C_SWITCH_SYSTEM): Don't define this to be "-ma" if

+        * s/aix3-2.h (LIBS_SYSTEM): Put -LIM -Liconv here.
+
+        * systty.h (HAVE_LTCHARS, HAVE_TCHARS): New macros; define them if
+        we have those structures, but *don't* define them if we have
+        TERMIOS, whose functions take care of those parameters; that
+        screws up AIX.

+        commands.
+        * sysdep.c (emacs_get_tty, emacs_set_tty, new_ltchars, new_tchars,

+
+        * xselect.c (x_get_local_selection): If no conversion function

+
+        * s/linux.h (HAVE_TCATTR): Defined.
+

+        LD_SWITCH_SYSTEM, OLDXMENU_OPTIONS): Add X11R5 directories to the

+        GCC.

+
+        * s/hpux8.h (LD_SWITCH_SYSTEM) [__GNUC__]: Pass -a archive to ld.
+        (HAVE_RANDOM): Defined.
+
+        * s/hpux.h (rand, srand): Definitions deleted.

+        * keyboard.c (read_char): If kbd_buffer_get_event returns nil,
+        redisplay and retry.
+        (kbd_buffer_get_event): If event is handled here, return nil.
+        (swallow_events): New function.
+        * process.c (wait_reading_process_input): Call that.
+
+        * ralloc.c (POINTER): Always use char *.
+
+        * s/sol2.h (C_SWITCH_X_SYSTEM): Deleted.

+        Fix mismatch in arg names.
+
+        * xfns.c (Fx_open_connection): Set xrm_option correctly.
+
+1993-05-25  David J. MacKenzie  (djm@wiki.eng.umd.edu)
+
+        * xfns.c (x_figure_window_size): Make the default frame coords (0,0).
+
+1993-05-25  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)
+
+        * Version 19.8 released.
+
+1993-05-25  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)
+
+        * xfns.c: Clear out the old face stuff.
+        (x_face_table, n_faces, x_set_face, x_set_glyph, Fx_set_face_font,
+        Fx_set_face, Fx_get_face): Removed.
+        (syms_of_xfns): Remove defsubr for Fx_set_face.
+
+        Arrange for font names to get fully resolved - no wildcards.
+        * xfns.c (x_set_frame_parameters): Store the value in the frame
+        parameter alist before we call the setter function, so the setter
+        function can touch up the value if it chooses.
+        (x_set_foreground_color, x_set_background_color): Call
+        recompute_basic_faces, so their GC's will reflect the changes.
+        (x_new_font): Add extern declaration - this returns a Lisp_Object
+        now, the fully resolved font name.
+        (x_set_font): Accept the fully resolved name from x_new_font, and
+        put it in the frame's parameter alist.  Call recompute_basic_faces.
+        * xterm.c (x_new_font): Return the fully resolved font name, Qnil
+        (if no match), or Qt (match, but unacceptable metrics).
+        * xterm.c (x_new_font): Don't call init_frame_faces.
+
+        * xterm.h: New section for declarations for xfaces.c.
+        (init_frame_faces, free_frame_faces, intern_face,
+        face_name_id_number, same_size_fonts, recompute_basic_faces,
+        compute_char_face, compute_glyph_face): Declare these here.
+        * xfaces.c (same_size_fonts): We can now remove this extern
+        declaration.
+        * xfns.c (face_name_id_number): Likewise.
+        * xterm.c (intern_face): Likewise.
+
+        * xterm.c (dumpglyphs): Remember that the default faces can have
+        null fonts, too.
+
+        * xfns.c (Fx_list_fonts): Remember that FACE may not have a font
+        specified.  Don't specify 30000 as the maximum limit on the number
+        of fontns returned  - 2000 is more reasonable. 
+
+        * xfaces.c (build_face, unload_font, free_frame_faces): Don't
+        forget to block input while making X calls.
+
+        Treat faces as structures specifying modifications to the frame's
+        parameters, rather than things which need to specify a complete
+        set of parameters by themselves.
+        * xfaces.c (init_frame_faces): Don't set up the two frame display
+        faces by querying the GC - just leave all their fields blank, and
+        call recompute_basic_faces, letting build_face do the work of
+        consulting the frame when necessary.
+        (recompute_basic_faces): New function.
+        (compute_base_faces): New function for obtaining the "identity"
+        for compute_char_face and compute_glyph_face.
+        (compute_char_face, compute_glyph_face): Call it, instead of copying
+        FRAME_DEFAULT_FACE.
+        * xfns.c (x_make_gc): No need to call init_frame_faces here.
+
+        * xfaces.c (intern_frame_face): This can be static.
+
+        * dispextern.h (struct face): New field - `copy', to help us with
+        resource allocation.
+        * xfaces.c (free_frame_faces): Do free the first two faces; don't
+        free anything from a face that's a copy.
+        (intern_frame_face): Mark every face we intern as a copy; its
+        resources are actually a combination of the real faces.
+        (Fset_face_attribute_internal): No need to check if we're trying
+        to free one of the frame's GC's; they never enter into the
+        picture.
+
+        * casetab.c: Fix formatting, so as not to confuse etags.
+
+        * xfns.c (Fx_list_fonts): New function.
+        (face_name_id_number): Add extern declaration for this.
+        * xfaces.c (face_name_id_number): Make this externally visible,
+        and make the FRAME argument a FRAME_PTR, not a Lisp_Object.
+        (compute_char_face): Call face_name_id_number properly.
+
+        * xfaces.c (unload_color): Don't free the pixel for now.
+
+        * xfaces.c (merge_faces): You can't tell if a font is a
+        character-cell font or not by testing whether or not it has a
+        per_char table.  They all do.
+        * xterm.c (x_new_font): Same deal.
+        * xfns.c (Fx_list_fonts): Same deal.
+
+        * m/iris4d.h: Dyke out the section which specifies how to get the
+        load average.
+
+        * paths.h (PATH_INFO): New path, to edited by the configuration
+        process.
+        * callproc.c (Vconfigure_info_directory): New variable, used
+        internally by build process.
+        (syms_of_callproc): DEFVAR it and initialize it.
+
+        * keyboard.c (Fcurrent_input_mode): Use XFASTINT to build the last
+        element of the return value, not XSETINT.
+
+1993-05-24  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)
+
+        Changes for OSF/1:
+        * mem-limits.h [__osf__ && (__mips || mips)]: #include
+        <sys/time.h> and <sys/resource.h>.
+        (get_lim_data): OSF wants a definition like BSD4_2's.
+        * s/osf1.h: #include "bsd4-3.h", not "s-bsd4-3.h".
+
+        * ymakefile (LIBX): Put LD_SWITCH_X_SITE before the libraries, so
+        it actually has an effect.
+
+        Some makes can't handle form feed characters in their makefiles.
+        * s/usg5-3.h: Remove form feed.
+        * s/template.h, m/template.h: Remove form feeds.
+
+        * xfns.c (select_visual): Include the screen number in the
+        template of things XGetVisualInfo must match.

+
+1993-05-24  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+        * keyboard.c (modify_event_symbol): If a name_table elt is null,
+        generate a name to use.  Don't crash.
+
+        * fileio.c (Fread_file_name): If input is empty, do return the default
+        even if !insert_default_directory.
+
+        * xterm.c (XTread_socket): For ConfigureNotify event,
+        translate coordinates if send_event field is false
+        provided the x-coord value is not large.
+
+1993-05-24  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

+
+1993-05-24  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)

+        ro_fsys, not XSTRING (foo).
+
+        * xterm.c (x_new_font): Reject fonts with varying spacing.  We
+        don't support them yet.
+        * xfns.c (x_set_font): Report the error message properly.
+
+        * xfns.c (Fx_parse_geometry): No need to call check_x here; it
+        doesn't interact with the server at all, and we need it in order
+        to create our first frame.
+
+1993-05-24  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+        * s/linux.h (HAVE_SETSID): Defined.

+
+        * syssignal.h (sys_signal): Declare the second argument to have
+        type signal_handler_t.  We're told this is necessary for Linux.
+
+1993-05-24  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+        * s/dgux.h (NO_GET_LOAD_AVG): Define, if __GNUC__.

+
+        * s/hpux8.h (NO_SIOCTL_H): Defined.

+
+1993-05-23  Jim Blandy  (jimb@geech.gnu.ai.mit.edu)
+
+        Changes for SGI from Matthew J Brown <mjb@doc.ic.ac.uk>.
+        * m/iris4d.h, m/iris5d.h: Don't use the --cckr CC switch if we're
+        using GCC.
+        * m/iris4d.h (NEED_SIOCTL): Move this to...
+        * s/irix3-3.h (NEED_SIOCTL): ... here; apparently it's not
+        necessary in irix4-0.h.
+        * s/irix4-0.h: Remove declaration of getpty; apparently Irix 4.0
+        already declares this elsewhere.
+        (PTY_TTY_NAME_SPRINTF): #undef this before re-#defining it.
+        * m/ibmps2-aix.h, m/pfa50.h, s/hpux.h, s/isc2-2.h, s/linux.h,
+        s/sco4.h, s/usg5-4.h: Remove HAVE_RENAME; configure guesses that now.
+
+        * config.h.in (LD_SWITCH_X_SITE, C_SWITCH_X_SITE): Change the
+        #defines to #undef's, so ../configure knows it should tweak them.
+
+        * xterm.c (x_scroll_bar_report_motion): Set *TIME whether or not
+        the mouse is over a scroll bar.
+
+        * xfaces.c (Fset_face_attribute_internal): Don't free the frame's
+        normal_gc or reverse_gc.
+
+        * keyboard.c (make_lispy_movement): Deal properly with mouse
+        motion outside of all windows.
+
+        * lisp.h (GLYPH_FACE): Remember that the face portion of a glyph
+        can be 24 bits, not just eight.
+
+1993-05-23  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+        * xterm.c: Move signal.h and stdio.h before config.h.
+
+        * editfns.c (Fcurrent_time_zone): Assign gmt, instead of init.
+
+1993-05-22  Jim Blandy  (jimb@geech.gnu.ai.mit.edu)

+
+        * puresize.h [not HAVE_X_WINDOWS] (PURESIZE): Make this 185k,
+        not 196k.  We're actually using ~180k.
+
+        * editfns.c: #include <sys/types.h>, to get time_t for Eggert's
+        changes.

+        * keyboard.c (modifier_names): Update to match *_modifier in termhooks.
+
+1993-05-22  Jim Blandy  (jimb@geech.gnu.ai.mit.edu)
+
+        * xterm.c (x_scroll_bar_handle_click): Never grab the scroll bar;
+        that feature requires more support to work correctly.
+
+        * keyboard.c (make_ctrl_char): New function.
+        (read_char): Call it.
+        (kbd_buffer_store_event): Call it to see if the new character is
+        the quit or stop character.
+        (make_lispy_event): Call it.

+
+1993-05-21  Jim Blandy  (jimb@geech.gnu.ai.mit.edu)

+        * process.c (Fopen_network_stream): Deal with older systems, which
+        only have the h_addr field in their struct hostent.
+
+        * systty.h [SYSV_PTYS]: #include <sys/types.h>.  Francesco
+        Potorti` <pot@fly.CNUCE.CNR.IT> says it's necessary on his
+        machine, and it should be harmless.
+
+1993-05-21  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+        * sysdep.c (wait_for_termination): Copy code from 18.59

+
+1993-05-21  Jim Blandy  (jimb@geech.gnu.ai.mit.edu)
+
+        * ymakefile (alloca.o): #define malloc and free to be xmalloc and
+        xfree on the command line of this compilation.
+
+        * s/sco4.h: (TIME_WITH_SYS_TIME): This is no longer needed.
+
+        * s/linux.h: Remove copyright notices by Michael K. Johnson and
+        Rik Faith.  They have both sent in papers now which make their
+        changes public domain.
+
+        * sysdep.c (sys_suspend): Set synch_process_alive, so that
+        wait_for_termination has something to wait for.
+
+1993-05-21  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+        * xdisp.c (display_text_line): Highlight only in selected window.

+
+        * dispnew.c (preserve_other_columns): Remember to multiply the
+        size argument to bcopy by the size of a glyph.
+
+1993-05-20  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+        * keyboard.c (read_key_sequence): Reexamine this_command
+        after pre-command-hook runs.
+
+        * xterm.c (x_find_modifier_meanings): If some keys are meta and alt,
+        make them just meta, not alt.
+
+1993-05-19  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)
+
+        Some time-handling patches from Paul Eggert:
+        * editfns.c (Fcurrent_time_zone): Take an optional argument specifying
+        what (absolute) time should be used to determine the current time zone.
+        Yield just offset and name of time zone, including DST correction.
+        Yield time zone offset in seconds, not minutes.
+        (lisp_time_argument, difftm): New functions.
+        (Fcurrent_time_string): Use lisp_time_argument.

+        EMACS_GET_TZ_NAMES): Remove.
+        * config.h.in: Add HAVE_TM_ZONE.
+
+        Some more changes from Michael K. Johnson for Linux.
+        * s/template.h: Mention that you should #define HAVE_TERMIO or
+        HAVE_TERMIOS, but not both, and that HAVE_TERMIOS is preferred.
+        * systty.h (EMACS_SET_TTY_PGRP): Don't assign the return value of
+        tcsetpgrp to *pgid; it's just a status value.
+        * config.h.in (HAVE_RANDOM): This shouldn't be defined on Linux
+        systems using XFree386, and perhaps is inappropriate in general.
+        * m/intel386.h: #undefine the integer size macros, since the Linux
+        <values.h> file #defines them itself.
+        * mem-limits.h (get_lim_data): Linux has the ulimit call; if it
+        fails, fall back on ULIMIT_BREAK_VALUE.
+        * process.c: Linux needs the WAITTYPE, etc. definitions.
+        * unexec.c (hdr, ohdr): Linux has the ordinary `struct exec' type;
+        no need to use SYSV names.
+        * s/linux.h: New file.
+
+        Some changes from Michael K. Johnson for Linux.
+        * sysdep.c (sys_siglist): Don't define this if HAVE_SYS_SIGLIST is
+        #defined.  That lets the system provide it, if it has it.
+        * syssignal.h (sigmask): Only define this if <signal.h> hasn't
+        given us a definition already.
+        * syssignal.h (sys_sigpause): Fix argument in prototype.
+        * sysdep.c (init_signals): The masks are called empty_mask and
+        full_mask, not signal_empty_mask and signal_full_mask.
+        (signal_handler_t): Moved ....
+        * syssignal.h: ... to here.
+        * systty.h (EMACS_SET_TTY_PGRP): Call tcsetpgrp with the correct
+        arguments.
+        * emacs.c (main): Don't try to establish signal handlers for
+        SIGBUS and SIGSYS unless they're actually #defined.
+
+        * systty.h [HAVE_TERMIO, __DGUX]: #include <sys/ioctl.h>.
+
+        * xdisp.c (redisplay_window): Compute the scrollbar start and end
+        properly.
+
+1993-05-19  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+        * keyboard.c (Fcurrent_input_mode): Return META as 3-way flag.

+        string.
+
+        * process.c (wait_reading_process_input): Undo change of April
+        29th, since that re-introduces the race condition the comments are
+        warning about.  Call clear_waiting_for_input before calling
+        status_notify, though.
+
+        * process.c (wait_reading_process_input): Don't forget to call
+        clear_waiting_for_input when we exit the loop because process
+        input has arrived.
+
+        Changes for Silicon Graphics Iris 5D.
+        * unexelfsgi.c: New file; like unexelf.c, but tolerates program
+        segments above BSS. 
+        * m/iris5d.h: New file.
+        * s/irix5-0.h: New file.

+
+        * xfns.c (x_set_menu_bar_lines): Fix typo in last change.

+
+1993-05-18  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)
+
+        * xdisp.c (display_text_line): If the newline (or C-m, in
+        selective-display) has a non-default face, apply that face to the
+        remainder of the line, so that the fill occupies the entire line.
+
+        * xterm.c (x_new_font): Tell the frame display faces about the
+        newly chosen font.
+
+        Make sure that all the display faces use fonts of the
+        same dimensions as the default face, so as not to confuse the rest
+        of the redisplay code.
+        * xfaces.c (same_size_fonts): New function.
+        (merge_faces): Only merge in a new font from the FROM face if it
+        is the same size as the font in the TO face.
+
+        * xfns.c (x_set_menu_bar_lines): Minibuffer-only frames can't have
+        menu bars.

+1993-05-18  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

+
+        * xfaces.c (free_frame_faces): Don't free the resources from the
+        first two faces.
+
+        * lisp.h (malloc, realloc): Declare these to return void *, to
+        avoid conflicts with ANSI header files.
+
+        * sysdep.c (reset_sys_modes): Test the return value of

+
+        * config.h.in (STDC_HEADERS, TIME_WITH_SYS_TIME,
+        CRAY_STACKSEG_END, STACK_DIRECTION): Add #undef clauses for these,
+        since otherwise the autoconf tests in configure.in won't do us
+        much good.
+
+1993-05-16  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+        * buffer.c (overlays_at): New arg EXTEND.

+        * xfaces.c (compute_char_face): Pass 0.
+        Try first with small overlay_vec, then use a big enough one.
+
+        * lread.c (syms_of_lread): Make Vcurrent_load_list ordinary Lisp var.
+        Set up Qcurrent_load_list.
+        (readevalloop): Specbind Qcurrent_load_list instead of ad-hoc saving.
+        (build_load_history): Do nothing when loading pure files.
+
+        * xterm.c (dumpglyphs): Create a temporary merged gc
+        when cursor falls on char with non-default face.

+
+        * xfaces.c (unload_color): Don't try to unload the standard black
+        or white pixel.
+
+        More changes from David Mackenzie.
+        * ymakefile (emacs): No need to edit srcdir into a lisp file and
+        then load it; we can just take advantage of the PATH_DUMPLOADSEARCH.
+        (crt0.o): Remember that crt0.c is in ${srcdir}.
+
+        Install David Mackenzie's patches to make ${srcdir} work.
+        * Makefile.in (srcdir, VPATH): Get this value from the top-level
+        Makefile.
+        (xmakefile): Use ${srcdir} to find the files from which we produce
+        xmakefile.  Edit the values for srcdir and VPATH into xmakefile.
+        * ymakefile (srcdir, VPATH): New definitions for the Makefile
+        to edit.

+        (emacs): Adjust dumping commands to deal with a separate source
+        directory.
+        (${etc}DOC): Pass `-d ${srcdir}' to make-docfile, to tell it where

+
+        * process.c (wait_reading_process_input): If we're running

+        according to David Mackenzie.

+
+        * systime.h: Borrow CPP sequence from getdate.y to include the

+        if region is being highlighted.
+
+        * xdisp.c (redisplay, redisplay_window): Don't use the cursor-motion

+        Don't sort if noverlays is 0 or 1.
+
+        * dispnew.c (direct_output_for_insert): Pass those args.
+        * xdisp.c (display_text_line): Pass those args,

+        * buffer.c (Fmove_overlay): If the overlay is in no buffer and the
+        BUFFER argument has been omitted, put it in the current buffer,
+        for symmetry with move-marker.
+
+        * buffer.c (Fdelete_overlay): Make the overlay's markers point
+        nowhere, not at 1.  Do this after calling redisplay_region, so
+        that code knows what section has changed.

+
+        * xdisp.c (display_menu_bar): Update FRAME_MENU_BAR_ITEMS here.
+        * keyboard.c (command_loop_1): Don't do it here.
+
+        * keymap.c (access_keymap): Handle any length vector.
+        (store_in_keymap): Likewise.
+        (Fcopy_keymap): Likewise.
+
+1993-05-14  Jim Blandy  (jimb@geech.gnu.ai.mit.edu)
+
+        * buffer.c (Foverlay_start, Foverlay_end, Foverlay_buffer,
+        Foverlay_properties): Functions moved here from subr.el.
+
+1993-05-13  Jim Blandy  (jimb@totoro.cs.oberlin.edu)
+
+        * xfaces.c (compute_char_face): When merging the overlays,
+        traverse sortvec, not overlay_vec; the latter isn't the one we
+        sorted.
+
+        * xterm.c (dumpglyphs): Give the cursor higher priority than the
+        face specified by the glyph under it.
+
+        * xterm.c (dumpglyphs): Move the underline up a row.  I dislike
+        the way X addresses pixels.  Quickdraw is much nicer.
+
+        * xfaces.c (intern_face): If the face has a GC, but it's not the
+        default or modeline face, abort.  Nothing but those two faces
+        should have a GC *and* be passed to intern_face.
+        (compute_char_face, compute_glyph_face): After copying
+        the frame's default face into face, to use as a base case for
+        calculation, set the `gc' member to zero; that way we don't have
+        things lying around that look like display faces but aren't.
+
+        * xfaces.c (intern_frame_face): When copying the new face into the
+        frame's face array, remember that the number of bytes to copy is
+        sizeof (*new_face), not sizeof (new_face).
+
+        * xfaces.c (compute_char_face): Assume that W is displaying the
+        current buffer.  Abort if it isn't.
+
+        * lisp.h (Lisp_Overlay): New tag.
+        (OVERLAYP): New predicate.
+        (CHECK_OVERLAY): New type-checker.
+        (Qoverlayp): New extern declaration.
+        * buffer.c (Foverlayp): New function.
+        (Qoverlayp): New atom.
+        (overlays_at, recenter_overlay_lists): Abort if we encounter an
+        invalid overlay.
+        (syms_of_buffer): defsubr Soverlayp; initialize Qoverlayp.
+        (Fdelete_overlay): Set the overlay's markers to point nowhere.
+        Use CHECK_OVERLAY instead of signalling a special error.
+        (Fmove_overlay, Foverlay_put): Use CHECK_OVERLAY instead of
+        signalling a special error.
+        (Foverlay_get): Use CHECK_OVERLAY.
+        * fns.c (internal_equal): Define this for overlays.
+        * buffer.h (OVERLAY_VALID): Define in terms of OVERLAYP.
+        * print.c (print): Give overlays their own print syntax.
+        * alloc.c (mark_object): Treat overlays like conses.
+
+        * lisp.h (FLOATP): Define this appropriately when LISP_FLOAT_TYPE
+        is not defined.
+
+        * buffer.c (Foverlay_get): Return Qnil if the requested property
+        is missing from the property list.
+
+        The text property routines can now modify buffers other
+        than the current one.
+        * insdel.c (modify_region): New argument BUFFER.  Select that
+        buffer while we prepare for the modification, and switch back when
+        we're done.
+        * textprop.c (add_properties, remove_properties): Pass
+        the buffer being modified as the first argument to modify_region.
+        * editfns.c (Fsubst_char_in_region, Ftranslate_region): Pass the
+        current_buffer as the first argument to modify_region.
+        * casefiddle.c (casify_region): Same.
+
+        * dispnew.c (direct_output_for_insert): Compute the face of the
+        character we're inserting properly.
+
+        * xterm.c (dumpglyphs): Pass the proper arguments to intern_face.
+
+        * xterm.c (dumpglyphs): Don't increment left twice.
+
+        * intervals.c (set_point): Check for point out of bounds before
+        checking for an empty interval tree. 
+
+        * cmds.c (Fforward_char): Check proposed new position, and then
+        set point, instead of setting point to a potentially invalid
+        position.
+
+        * lread.c, data.c: If STDC_HEADERS is #defined, include <stdlib.h>
+        to get the extern declarations for atof.  That's where it is in
+        POSIX.
+
+1993-05-12  Jim Blandy  (jimb@geech.gnu.ai.mit.edu)
+
+        * ymakefile (xfaces.o): Add window.h to the dependencies.
+
+        * xfaces.c (intern_frame_face): Exchange order of arguments, to
+        make callers correct.
+
+        * xfaces.c (compute_char_face): Notice the next property change
+        location correctly.
+
+        * xfaces.c (face_name_id_number): Return 0 (the default face) if
+        the name is undefined.
+
+        * xfaces.c (Fset_face_attribute_internal): Do nothing unless FRAME
+        is an X frame.
+
+        * xdisp.c (copy_rope, copy_part_of_rope): Add face argument.
+        (display_text_line): Initialize current_face to zero.   Apply it
+        to characters as we write them to the display matrix.
+        (display_string): Pass the new argument to copy_rope.
+
+        * xdisp.c (display_text_line): Handle the locations of face
+        changes properly.
+
+        * textprop.c (Fnext_single_property_change,
+        Fprevious_single_property_change): Pass arguments to textget in
+        the right order.
+
+        * ymakefile (xfns.o): Remove duplication of buffer.h in dependencies.
+
+        * ymakefile ($(OLDXMENU)): Remove extraneous call to `rm'.
+
+1993-05-12  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+        * keymap.c (Faccessible_keymaps): Use whatever size the vector has.
+        (Fwhere_is_internal): Likewise.
+        (describe_vector): Likewise.
+        (current_minor_maps): Call Findirect_function, so symbols
+        can be used in place of actual maps.
+
+        * xdisp.c (display_text_line): Use break; to exit loop at eol.
+        Duplicate the short MAKE_GLYPH loop after the main loop.
+        If no display table, do obey selective_display_ellipses.
+        (copy_part_of_rope): Arg FROM is now Lisp_Object *.
+
+        * xfaces.c: Do include window.h.
+        (compute_char_face): Supply third arg of Fget_text_property.
+
+        * keyboard.c (make_lispy_event): Don't set shift modifier for C-^.
+
+        * callproc.c (child_setup): Omit duplicates from new env array.
+
+1993-05-10  Jim Blandy  (jimb@geech.gnu.ai.mit.edu)
+
+        * fileio.c (ro_fsys) [SOLARIS_BROKEN_ACCESS]: Check for the
+        filesystem being ro, since Solaris 2.1 doesn't.
+        (file-writable-p): Call ro_fsys.
+        * s/sol2.h (SOLARIS_BROKEN_ACCESS): Define this.
+
+        * systime.h: Use the strategy from getdate.y to include the proper
+        combination of <time.h> and <sys/time.h>.
+
+        * xfns.c (Fx_create_frame): Use an XLFD name for the default font,
+        instead of "9x15" or whatever it was.
+
+        * xdisp.c (display_text_line): Make face-handling code conditional
+        on HAVE_X_WINDOWS macro.  Perhaps this isn't the best approach,
+        but it'll do for now.
+
+        * xdisp.c (display_text_line): We can't use the FRAME_DEFAULT_FACE
+        macro here; that's x-specific.  Just don't pass the second
+        argument.
+        * xfaces.c (compute_glyph_face): Remove the BASIC_FACE argument;
+        use F's default face.
+
+1993-05-09  Jim Blandy  (jimb@totoro.cs.oberlin.edu)
+
+        * xfaces.c (Fmake_face_internal): Do nothing for non-X frames.
+
+        * dispextern.h (struct face): Add cached_index member.
+        * xfaces.c (get_cached_face): Use it to avoid unnecessary
+        searches of face_vector.
+
+        * xfaces.c (intern_face): Renamed from get_display_face.
+
+        * xfns.c (x_make_gc): After building the GC's for the frame, call
+        init_frame_faces to set up the first two faces.
+        * xfaces.c (init_frame_faces): Don't just try to copy the default
+        and mode line faces from some other random frame; instead, consult
+        the normal_gc and reverse_gc members of the frame, and build the
+        faces based on their parameters.
+
+        Adjust the face computation functions to return frame face ID's,
+        not pointers to display faces; since we call these functions
+        during display construction, we don't want the display faces yet.
+        * xfaces.c (intern_frame_face): New function.
+        (compute_char_face, compute_glyph_face): Apply intern_frame_face
+        to the computed face, and return the frame face's ID, instead of
+        calling intern_face and returning a pointer to a display frame.
+
+        * xfaces.c: Describe the facial data structures.  It took me a
+        while to figure them out; perhaps this will save someone else the
+        trouble.
+
+        Arrange to tell redisplay about changes in overlays.
+        * xdisp.c (redisplay_region): New function.
+        * buffer.c (Fmove_overlay): Call redisplay_region on the areas the
+        overlay has enclosed or left.
+        (Fdelete_overlay): Call redisplay_region on the area the overlay
+        used to occupy.
+        (Foverlay_put): Call redisplay_region on the area the overlay now
+        occupies; we may have put a face property on it.
+
+        * buffer.c (Fmove_overlay): Doc fix.
+
+        * xdisp.c (redisplay): If we're doing a thorough redisplay (all
+        windows on all frames involved), go ahead and flush the GC cache -
+        call clear_face_vector.
+
+        * xdisp.c (display_text_line): Apply faces to characters
+        according to overlays and text properties; use
+        compute_char_face and compute_glyph_face to figure out what
+        face to use, and where a new face starts.
+        * xterm.c (dumpglyphs): Use the upper bits of the glyphs to decide
+        which frame face to use.  Call GLYPH_FOLLOW_ALIASES to make sure
+        we're implementing the glyph table properly.  If we're not using
+        the default or mode line face, call intern_face to find a display
+        face for the frame face selected by the glyph code.  Implement
+        underlining.  Remove the `font' argument; we have to derive this
+        from the frame and face anyway.  Change all callers.
+        * disptab.h (GLYPH_FOLLOW_ALIASES): New macro.
+
+        * xterm.c (x_destroy_window): Call free_frame_faces.
+
+        The GNU coding standards specify that CFLAGS should be left for
+        users to set.
+        * ymakefile (ALL_CFLAGS): Set this to the long string of
+        compilation switches, not CFLAGS.  Changed all uses.
+        (CFLAGS): Make this default to just -g.
+        (.c.o): Define new default rule, to make sure that the right flags
+        get to the compilations.
+
+1993-05-09  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+        * keyboard.c (read_char): Exit kbd macro if Vexecuting_macro is t.
+
+        * pwd.h: File deleted.
+
+1993-05-08  Jim Blandy  (jimb@totoro.cs.oberlin.edu)
+
+        * s/sunos4shr.h: Apply changes from David J. Mackenzie; this isn't
+        used by any configuration right now, but he's trying to make it
+        work.
+        #include "sunos4-1.h" instead of "bsd4-2.h".
+        (O_NDELAY): Don't define this.
+        (SYSTEM_MALLOC): Don't define this, either.
+        (LD_SWITCH_SYSTEM): Remove the definition for this.
+
+        * Makefile.in (DEFS): Remove this; we have configure build a
+        config.h file directly, instead of having lots of -D flags.
+
+        * Makefile.in (CFLAGS): Don't make this carry DEFS from the
+        configure script; the coding standards say that CFLAGS should be
+        left for the user to tweak.
+
+1993-05-08  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+        * keyboard.c (do_mouse_tracking): Now static.
+
+        * xmenu.c (Fx_popup_menu): Add a vector of prefix keys for the panes.
+        (keymap_panes): Allocate that vector.
+        (single_keymap_panes): Fill in that vector.
+        (xmenu_show): Return a list of events, not just one event.
+
+        * keyboard.c (read_char_menu_prompt): Expect Fx_popup_menu
+        to return a list of events.  Don't lose any of them.
+
+        * xfns.c (Fx_get_mouse_event, Fx_mouse_events): Code deleted.
+        * window.c (Vmouse_event): Var deleted.
+        (syms_of_window): Don't make it a Lisp var.
+
+        * keyboard.c (read_avail_input, Fset_input_mode): Make
+        meta_key a three-value variable to support 8-bit input.
+
+1993-05-07  Jim Blandy  (jimb@totoro.cs.oberlin.edu)
+
+        * ymakefile [__GNUC__ && __GNUC__ > 1] (LIB_GCC): Set this even if
+        LINKER is #defined.
+
+        * ymakefile ($(OLDXMENU)): Remove the link before we re-create it;
+        not all versions of ln have the `-f' flag.  Use the LN_S variable,
+        inherited from src/Makefile.
+
+        * Makefile.in (LN_S): New variable, edited by top Makefile.
+        (SUBMAKEFILE): New variable, containing all flags to pass to
+        recursive makes.
+
+        * config.h.in: Adjust this for use by autoconf's AC_CONFIG_HEADER,
+        instead of AC_OUTPUT.
+
+        * xfaces.c (get_display_face): Use face_eql instead of writing it out.
+
+1993-05-06  Jim Blandy  (jimb@totoro.cs.oberlin.edu)
+
+        * keymap.c (Fwhere_is_internal): If FIRSTONLY is non-nil, avoid
+        returning a non-ascii key sequence unless FIRSTONLY is the symbol
+        `non-ascii'.
+
+        * config.h.in: Remove mention of GLYPH datatype; that shouldn't be
+        a user option.
+        * lisp.h (GLYPH, MAKE_GLYPH, GLYPH_CHAR, GLYPH_FACE): New macros.
+
+1993-05-06  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+        * xfns.c (x_get_arg): Call Fintern, not intern.
+
+        * systime.h [SCO]: Include time.h.

+
+        * ymakefile (LIBXMENU): Delete -loldX.

+
+1993-05-05  Jim Blandy  (jimb@totoro.cs.oberlin.edu)
+
+        * s/template.h: Explain the relative significance of the SIGIO and
+        INTERRUPT_INPUT macros.
+
+        * ymakefile (buffer.o, insdel.o): Note that these files also
+        depend on blockinput.h.
+
+        * blockinput.h (UNBLOCK_INPUT): We cannot assume that SIGIO is
+        defined everywhere this file is #included; merge the two
+        definitions for defined (SIGIO) and ! defined (SIGIO) into one,
+        which calls reinvoke_input_signal if interrupt_input_pending is
+        set.
+        * keyboard.c (reinvoke_input_signal): New function.
+
+1993-05-04  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

+
+        * keyboard.c (syms_of_keyboard): Doc fix for

+
+        * lisp.h (CHAR_ALT, CHAR_SUPER, CHAR_HYPER, CHAR_SHIFT, CHAR_CTL,

+
+1993-05-02  Jim Blandy  (jimb@totoro.cs.oberlin.edu)
+
+        * keymap.c (Fdefine_prefix_command): Doc fix.

+
+1993-05-01  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

+
+1993-04-30  Jim Blandy  (jimb@totoro.cs.oberlin.edu)

+
+1993-04-29  Jim Blandy  (jimb@totoro.cs.oberlin.edu)
+
+        Implement extra_keyboard_modifiers properly.
+        * keyboard.c (syms_of_keyboard): Doc fix for
+        extra-keyboard-modifiers; use the same modifier bits as we do for
+        characters.
+        (read_char): Apply all the modifiers in extra_keyboard_modifiers
+        to the input characters, so you can get hyper, super, and the rest
+        of the gang.
+        * xterm.c (x_emacs_to_x_modifiers): New function.
+        (x_convert_modifiers): Renamed to x_x_to_emacs_modifiers, for
+        consistency.  Callers changed.
+        (XTread_socket): Apply x_emacs_to_x_modifiers to
+        extra_keyboard_modifiers before setting the state member of the
+        event; this will get all the modifiers on ASCII characters.
+
+        * xterm.c (x_text_icon): Don't call XSetIconName; it should be
+        unnecessary, and perhaps it's killing the icon pixmap.
+
+        * lisp.h (CHAR_ALT, CHAR_SUPER, CHAR_HYPER): New constants, in
+        case we need them.
+        * termhooks.h (alt_modifier, super_modifier, hyper_modifier,
+        shift_modifier, ctrl_modifier, meta_modifier): Define these in
+        terms of the CHAR_mumble macros, to avoid having the same thing
+        defined in two places.
+
+        * keyboard.c (kbd_buffer_get_event): Don't generate switch-frame
+        events if they'd only switch to the frame already selected.  This
+        avoids lots of extra switch-frame events when using a separate
+        minibuffer.
+
+1993-04-29  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+        * keyboard.c (Fthis_command_keys): Doc fix.
+
+        * process.c (wait_reading_process_input): Move the status_notify
+        call before the set_waiting_for_input call.
+
+        * fileio.c (Fexpand_file_name): Undo last change--too risky for now.
+
+        * data.c (Fdefine_function): New function (same code as Fdefalias).
+
+1993-04-28  Eric S. Raymond  (eric@mole.gnu.ai.mit.edu)

+
+1993-04-27  Eric S. Raymond  (eric@mole.gnu.ai.mit.edu)
+
+        * eval.c (un_autoload): Don't try to save old autoload forms when
+        we load something in.  Something about the code now conditioned
+        out by UNLOAD was screwing up ordinary autoloads, notably of
+        picture.el.  When I figure out what, I'll fix and re-enable this
+        code.
+
+1993-04-27  Jim Blandy  (jimb@totoro.cs.oberlin.edu)
+
+        * buffer.c (syms_of_buffer): Doc fix for buffer-display-table.
+
+        * systime.h: Doc fix.
+        (EMACS_SET_USECS): Remember that a `usec' is a microsecond, not a
+        millisecond.  What's three orders of magnitude between friends?
+        * dispnew.c (Fsit_for, Fsleep_for): Remember to multiply the
+        `milliseconds' argument by 1000 to get microseconds.
+
+1993-04-26  Roland McGrath  (roland@geech.gnu.ai.mit.edu)
+
+        * fileio.c (Fexpand_file_name):

+
+        * config.h.in (getenv): Don't test THIS_IS_YMAKEFILE to see if we

+1993-04-24  Jim Blandy  (jimb@totoro.cs.oberlin.edu)
+
+        Make the modifier manipulation functions more robust.  The old way

+        * termhooks.h (alt_modifier, super_modifier, hyper_modifier,
+        shift_modifier, ctrl_modifier, meta_modifier): Shift these all
+        down one bit in value, to avoid sign extension problems.

+1993-04-23  Eric S. Raymond  (eric@mole.gnu.ai.mit.edu)
+
+        * data.c (Fdefine_function):
+        Changed name back to Fdefalias, so we get things

+        conses in the current-globals list.
+
+        * lread.c (readevalloop):

+        * fileio.c (Fmake_symbolic_link): If a file already exists under

+        if some file has #defined HAVE_VOLATILE.
+
+        * emacs.c (SEPCHAR): Instead of defining this to be ',' on VMS and
+        ':' elsewhere, just have it default to ':' if not #defined, and
+        #define it to be ',' in s/vms.h; OS/2 will need it to be ';'.
+        * s/vms.h (SEPCHAR): #define this to be ','.
+        * s/template.h (SEPCHAR): Mention this.
+
+1993-04-13  Jim Blandy  (jimb@totoro.cs.oberlin.edu)
+
+        * s/vms.h (xfree): #define this to emacs_xfree, to avoid case
+        conflict with XFree; on VMS, external symbols are case-insensitive.
+
+        * s/usg5-4.h (HAVE_GETTIMEOFDAY): Deleted; ../configure figures
+        that out now.
+
+        Changes for Emacs 19 from Thorsten Ohl <ohl@chico.harvard.edu>:
+        * s/mach2.h: copied from the Emacs 18.59 distribution.
+        Don't define NO_REMAP, define START_FILES as
+        `pre-crt0.o' instead.  Define LIB_MATH as `-lm', to override the
+        default `-lm -lc' (there is no libc on the NeXT).
+        * ymakefile (STARTFILES): Allow config.h to set this value even if
+        ORDINARY_LINK is defined.
+        * unexnext.c: Fix subdirectories for the machine dependent include
+        files for NeXTStep 3.0; #include <mach/mach.h> and
+        <mach-o/loader.h> instead of <mach.h> and <sys/loader.h>.
+        (getsectbyname): Remove prototype for this; the system #include
+        files take care of that.
+        (malloc_cookie): New variable.
+        (unexec_doit): Set malloc_cookie to the result returned by
+        malloc_freezedry.
+        * emacs.c (main): Declare malloc_cookie to be extern, so that we can
+        get the value set when we dumped and pass it to malloc_jumpstart.
+        * systime.h: The NeXT has a timezone function.
+
+1993-04-12  Jim Blandy  (jimb@totoro.cs.oberlin.edu)
+
+        * ymakefile ($(OLDXMENU)): Remove $(OLDXMENU) before trying to

+
+1993-04-09  Jim Blandy  (jimb@totoro.cs.oberlin.edu)
+
+        * keyboard.c (command_loop_1): Rebuild menu bar if
+        update_mode_lines is set.
+
+        long_to_cons and cons_to_long are generally useful things; they're
+        needed whether or not X is defined.
+        * xselect.c (long_to_cons, cons_to_long): Moved from here...
+        * data.c    (long_to_cons, cons_to_long): ... to here.
+        * lisp.h    (long_to_cons, cons_to_long): Add extern declaration.
+
+        * xmenu.c (Qmenu_enable): Definition moved...
+        (syms_of_xmenu): ... along with initialization ...
+        * keyboard.c (Qmenu_enable): ... to here ...
+        (syms_of_keyboard): ... and here.
+
+        * keyboard.c (kbd_buffer_get_event): If we get a selection clear
+        or selection request event, but we were compiled without the
+        window-system-specific code to handle it, abort.  Don't try to
+        call a function which doesn't exist.
+
+        * keyboard.c (make_lispy_event): In the code which processes mouse
+        clicks, declare f to be a FRAME_PTR, not a struct frame *; this
+        works when MULTI_FRAME is not #defined.
+
+        * xfaces.c (sort_overlays): Define this to be static, as declared.
+
+        * callproc.c (relocate_fd): Make messages string literals, not
+        initialized arrays.
+
+        * alloc.c (__malloc_hook, __realloc_hook, __free_hook): Declare

+        void *, not void.
+
+        Adjust for autoconf merger.
+        * config.h.in: Add extra line to top, in case autoconf gets fixed
+        and decides not to add Makefile-style comments to the top of the
+        files it generates which we are forced to lop off.
+        Indicate that the boolean macros here get their definitions via
+        the DEFS Makefile variable.
+        Adjust the operating system and machine #includes to use
+        autoload's @cookies@.
+        (RETSIGTYPE): Give this a default value.
+        (SIGTYPE): Set this from RETSIGTYPE.
+        (LD_SWITCH_X_SITE, C_SWITCH_X_SITE): Get values via @cookies@.
+        * Makefile.in (DEFS): Renamed from CONFIG_CFLAGS.
+        (xmakefile): Pass CFLAGS to ${CPP}.
+
+        * buffer.c (Fmake_overlay, Fmove_overlay): New optional BUFFER
+        arguments.
+        (recenter_overlay_lists): New argument BUF, to use instead of the
+        current buffer.
+        (Foverlay_recenter): Pass the appropriate arguments to
+        recenter_overlay_lists.
+
+        * buffer.c (Fdelete_overlay): Don't assume that overlay is in the
+        current buffer.  Don't forget to declare the argument a Lisp_Object.
+
+        * dispnew.c (getenv): Extern declaration deleted; this is done in
+        config.h.
+
+        * Makefile.in (tagsfiles): Remove external-lisp from this list of
+        files; we're not distributing it, so the normal build process
+        shouldn't depend on it.
+
+        * dispnew.c (init_display): Compare the return value of getenv to
+        zero before setting display_arg, instead of just using the pointer
+        as a truth value.
+
+1993-04-08  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+        * xdisp.c (message, message1): If noninteractive and
+        cursor_in_echo_area, don't print a newline at end of message.

+
+        * keyboard.c (echo_dash): Do nothing if echoptr is 0.
+
+        * buffer.c (Fkill_all_local_variables): Store each var's current value

+
+1993-04-07  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)
+
+        * m/imbrs6000.h: If we're using GCC, define ORDINARY_LINK instead
+        of defining LINKER to use cc.
+        * s/aix3-1.h (LINKER): Don't use cc for linking command if we're
+        using GCC.
+        * s/aix3-2.h (SYSTEM_MALLOC): Undefine this.
+
+        * xterm.c (updating_frame): Declare this extern instead of static,
+        so it's the same variable as the updating_frame in term.c.
+        (XTupdate_begin, XTupdate_end): Don't bother to set
+        updating_frame; the term.c functions take care of that for us.
+
+1993-04-05  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)
+
+        * s/vms.h (EXEC_SUFFIXES): Add definition for this.

+
+        * xfaces.c: Doc fixes.
+
+        Put interrupt input blocking in a separate file from xterm.h.
+        This isn't specific to X, and it allows us to avoid #including
+        xterm.h in files that don't really have anything to do with X.
+        * blockinput.h: New file.
+        * xterm.h (BLOCK_INPUT, UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT,
+        UNBLOCK_INPUT_RESIGNAL): These are now in blockinput.h.
+        (x_input_blocked, x_pending_input): Deleted; there are analogs

+        (XTread_socket): Test and set interrupt_input_blocked and
+        interrupt_input_pending instead of the old variables.
+        * alloc.c, xfaces.c, xfns.c, xmenu.c, xselect.c, keymap.c:
+        #include blockinput.h.
+        * eval.c: #include blockinput.h instead of xterm.h.
+        * keyboard.c: #include blockinput.h.

+        malloc heap.
+        * alloc.c: (xfree): New function, to make it easy to free things

+        Fmake_symbol, Fmake_marker, make_uninit_string, Fgarbage_collect):
+        Use xmalloc instead of malloc; don't bother to check if out of
+        memory here.
+        (Fgarbage_collect): Call xrealloc instead of realloc.
+        * buffer.c: Use xmalloc and xfree instead of malloc and free;
+        don't bother to check if out of memory here.
+        (Fget_buffer_create): Put BLOCK_INPUT/UNBLOCK_INPUT pair around
+        calls to ralloc routines.
+        * insdel.c: Same.
+        * lisp.h (xfree): New extern declaration.
+        * xfaces.c (xfree): Don't #define this to be free; use the
+        definition in alloc.c.
+        * dispnew.c, doc.c, doprnt.c, fileio.c, lread.c, term.c, xfns.c,
+        xmenu.c, xterm.c: Use xfree instead of free.
+        * hftctl.c: Use xfree and xmalloc instead of free and malloc.
+        * keymap.c (current_minor_maps): BLOCK_INPUT while calling realloc
+        and malloc.
+        * search.c: Since the regexp routines can malloc, BLOCK_INPUT
+        while runing them.  #include blockinput.h.
+        * sysdep.c: #include blockinput.h.  Call xfree and xmalloc instead
+        of free and malloc.  BLOCK_INPUT around routines which we know
+        will call malloc.
+        
+        ymakefile (keyboard.o, keymap.o, search.o, sysdep.o, xfaces.o,
+        xfns.o, xmenu.o, xterm.o, xselect.o, alloc.o, eval.o): Note that
+        these depend on blockinput.h.
+
+        * keyboard.c (parse_modifiers, apply_modifiers): Make sure we're
+        not trying to create modifier masks using integers which are
+        unrepresentable as lisp values.
+
+1993-03-30  Jim Blandy  (jimb@geech.gnu.ai.mit.edu)
+
+        New macros NULL_DEVICE and EXEC_SUFFIXES, to give the name of the
+        equivalent of /dev/null, and the suffixes used by executable
+        files.  This is simple, and helps people porting Emacs to other
+        operating systems.
+        * process.h (NULL_DEVICE): Give this a default value.
+        * process.c (Fstart_process): Pass EXEC_SUFFIXES to openp.

+        * s/vms.h (NULL_DEVICE): #define this.
+
+        Rename int-to-string to number-to-string, since it can handle
+        floating-point as well as integer arguments.  subr.el defines the
+        former as an alias for the latter.
+        * data.c (Fnumber_to_string): Renamed from Fint_to_string.
+        (wrong_type_argument): Adjust caller.
+        (syms_of_data): Adjust defsubr.

+        * fileio.c (Fwrite_region): Don't fail to set visit_file.
+
+        * keyboard.c (command_loop_1): Clear force_start of selected_window
+        after reading each key sequence.
+        (read_char): Clear Vquit_flag when we return C-g for it.
+
+        * fileio.c (Fexpand_file_name): Default DEFALT at beginning,

+        If we're doing ordinary linking, define LIB_STANDARD appropriately.

+
+        * m/intel386.h (LIB_STANDARD): If USG5_4 is #defined, there's no
+        need to include `-lPW'; that has been merged with `-lc'.
+
+        * emacs.c (__do_global_ctors, __do_global_ctors_aux,
+        __do_global_dtors, __CTOR_LIST__, __DTOR_LIST__, __main): Don't

+        * emacs.c (fatal_error_signal): Unblock the signal which we're

+
+        Don't generate switch-frame events by checking Vlast_event_frame;

+
+        * data.c (Fstring_to_number): Just skip tabs and spaces; don't use

+        * keyboard.c (Fread_key_sequence): Backslash the newlines in this
+        docstring.
+        * textprop.c (Fget_text_property): Same.

+        empty string.

+
+1993-02-17  Michael I Bushnell  (mib@geech.gnu.ai.mit.edu)
+
+        * process.c (Fstart_process): Jimb's change of December 11
+        had a misplaced paren.  This only became apparent because of
+        jimb's change on February 8 to Fexpand_file_name.
+        * callproc.c (Fcall_process): Ditto.
+
+1993-02-17  Jim Blandy  (jimb@totoro.cs.oberlin.edu)

+
+        * xterm.c (x_set_window_size): Call change_frame_size instead of
+        just setting the `rows' and `cols' members of the frame, and
+        leaving the window tree in complete disarray.
+
+        * dispnew.c (remake_frame_glyphs): When re-allocating the frame's
+        message buffer when echo_area_glyphs is pointing at it, relocate
+        echo_area_glyphs too.  Same for previous_echo_glyphs.
+        * window.h (previous_echo_glyphs): Add extern declaration for this.
+
+        * frame.c (Fframe_parameters): Report the `minibuffer' parameter of
+        minibufferless frames as nil, not `none'.
+        (Qnone): Remove declaration and initialization for this.  It's not
+        needed anymore.
+        * xfns.c (Qnone): Add them here; we still accept "none" as a valid
+        value for the `minibuffer' parameter.
+
+        * xfns.c (x_frame_params): Remember that the parameters are called
+        "auto-raise" and "auto-lower", not "autoraise" and "autolower".
+
+        * xdisp.c (message): Set echo_frame to the frame whose message buf
+        we want to use, not to the message buf itself.

+
+1993-02-10  Jim Blandy  (jimb@totoro.cs.oberlin.edu)
+
+        * fileio.c (Fdo_auto_save): If NO_MESSAGE is non-nil, don't tell
+        users that buffers have shrunk a lot.  This is called when Emacs
+        is crashing, so we don't want to run any code that isn't
+        absolutely necessary.  Also, autosave buffers which don't have
+        specially handled autosave file names first.
+
+1993-02-10  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+        * editfns.c (Fcompare_buffer_substrings): Ignore case

+
+        * xdisp.c (message): Use the message buffer of the frame we're

+        the selected frame.
+
+1993-02-07  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+        * Makefile (emacs, temacs): Add no-op commands to these rules.

+1993-02-06  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

+
+1993-01-29  Jim Blandy  (jimb@geech.gnu.ai.mit.edu)
+
+        * window.c (Fscroll_left, Fscroll_right): Don't forget to apply
+        XWINDOW to selected_window before passing it to window_internal_width.
+
+        * xmenu.c (Fx_popup_menu): Don't forget to turn the frame-relative
+        coordinates for the menu position into root-window-relative
+        coordinates.
+
+        * lread.c (read1): Although digits followed by a '.' are an
+        integer, a single . by itself (like, say, \.) should be a symbol.
+
+1993-01-25  Jim Blandy  (jimb@geech.gnu.ai.mit.edu)
+
+        * fns.c (internal_equal): Protect the clause for comparing numbers

+1993-01-25  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+        * s/hpux8.h [__GNUC__] (LD_SWITCH_SYSTEM): Remove -a.

+
+        * lread.c (read1): Treat a string of digits ending in a period as

+        * buffer.h (Vfirst_change_function): Renamed to Vfirst_change_hook.
+        (Qfirst_change_hook): Added declaration.
+        * insdel.c (signal_before_change): Change references to
+        Vfirst_change_function, and apply Vrun_hooks to
+        Qfirst_change_hook, instead of just calling Vfirst_change_function
+        directly.
+
+        x-selection-value has been renamed to x-selection.
+        x-own-selection has been renamed to x-set-selection, and the order
+        of its arguments has been reversed, for consistency with other
+        lisp functions like put and aset.
+        * xselect.c (Fx_own_selection): Rename to Fx_set_selection, 
+        reverse the order of the args, and therefore make the type
+        non-optional.  Doc fix.
+        (Fx_selection_value): Rename to Fx_selection; make the type
+        argument non-optional, for symmetry with Fx_set_selection.  Doc
+        fix.
+        (syms_of_xselect): Adjusted.
+
+        * xselect.c (Fx_own_selection, Fx_selection_value): Remove "#if
+        0"'ed code which made cut buffers look like a special selection
+        type.
+
+        * xfns.c (Vx_selection_value): Removed extern declaration for
+        this; it's never used.
+
+        * data.c (Fcompiled_function_p): Renamed to Fbyte_code_function_p.
+        (syms_of_data): Adjusted.
+
+        * data.c (Fnumberp, Fnumber_or_marker_p): Use the NUMBERP macro,
+        instead of writing it out.
+
+        * fns.c (internal_equal): If the operands are both numbers,
+        compare them numerically, so that (equal 1.0 1) => t.
+        Compare Lisp_Compiled objects like vectors.
+
+        Add lisp functions to raise and lower frames.
+        * termhooks.h (frame_raise_lower_hook): New hook.

+
+        Make the cursor style a frame parameter.
+        * xterm.h (struct x_display): Rename the `text_cursor_kind' member
+        to `current_cursor'; add new member `desired_cursor'.
+        (FRAME_DESIRED_CURSOR): New accessor for new member.
+        * xterm.c (x_display_bar_cursor): Rewritten so as not to damage
+        the characters the cursor is displayed over, and to handle
+        transitions between box and bar styles.
+        (x_display_bar_cursor, x_display_box_cursor): Use current_cursor
+        instead of text_cursor_kind.
+        (Vbar_cursor): Delete external declaration.
+        (x_display_cursor): Use the FRAME_DESIRED_CURSOR accessor instead
+        of Vbar_cursor to decide how to draw the cursor.
+        * xfns.c (Vbar_cursor): Remove definition.
+        (Qbar, Qbox, Qcursor_type): New symbols. 
+        (syms_of_xfns): Init and staticpro them; remove DEFVAR for
+        Vbar_cursor.
+        (x_set_cursor_type): New setter.
+        (x_frame_parms): Add it to the list.
+        (Fx_create_frame): Get default values for the cursor type.
+
+        * frame.c (Fmouse_position): Pass the appropriate arguments to
+        *mouse_position_hook; the protocol was changed, but this caller
+        wasn't fixed.
+
+        * xterm.c (XTclear_frame): Call x_scrollbar_clear.
+        (x_scrollbar_clear): New function.
+
+        * xterm.c (XTflash): Totally rewritten.  Only defined if
+        HAVE_TIMEVAL and HAVE_SELECT are defined, since we use select for
+        our timing.
+        (timeval_subtract): New function, to help XTflash.
+        (x_invert_frame): Removed.  This didn't work anyway.
+        (XTring_bell): Remove "#if 0" around call to XTflash, and remove
+        calls to x_invert_frame.  If both HAVE_TIMEVAL and HAVE_SELECT
+        aren't defined, then just do the ordinary beep.
+
+        * window.c (Fscroll_other_window): Prefer windows on the selected
+        frame, then look for windows on other visible frames.
+
+        * keyboard.c (Fmouse_click_p): Removed; with the 'e' spec, this
+        isn't necessary anymore.
+        (syms_of_keyboard): Remove defsubr for it.
+        * keyboard.h (Fmouse_click_p): Remove extern declaration for it.
+
+        * xfns.c (gray_bits): Remove this declaration; the same data is in
+        <X11/bitmaps/gray>.  #include that instead.
+        [not HAVE_X11] (x_set_border_pixel): Use gray_width and
+        gray_height, instead of assuming that the bitmap is 16x16.
+        (x_make_gc): Instead of creating a pixmap and then calling
+        XPutImage to make it into a grey stipple, just call
+        XCreatePixmapFromBitmapData to do it all at once.
+
+        * xterm.c (x_text_icon): Move the request for font information
+        into the "not HAVE_X11" part of the function; the X11 code doesn't
+        need this.
+
+        * xterm.c (x_wm_set_icon_pixmap): Instead of setting the
+        icon_pixmap to None, just remove IconPixmapHint from the flags of
+        the XWMHints structure.
+
+        * window.c (Fprevious_frame): Use prev_frame when we get to the
+        end of the current frame, not next_frame.  Doc fix.
+        * frame.c (prev_frame): Remove "#if 0" from this function.  It
+        turns out we do need it, to make prev_frame work right.
+
+        * frame.c (next_frame): Check that FRAME is a live frame.
+
+        * frame.c (Fselect_frame): Remove "#ifdef MULTI_FRAME" clause
+        around the code which calls Ffocus_frame; this code is already
+        inside an "#ifdef MULTI_FRAME" clause.
+        (next_frame, prev_frame, Fnext_frame): For the same reasons,
+        remove the "#ifdef MULTI_FRAME" clause around these functions.
+
+        unread-command-event has been replaced by unread-command-events.
+        * commands.h (unread_command_event): Change extern declaration.
+        * keyboard.c (unread_command_event): Change the definition.
+        (syms_of_keyboard): Change DEFVAR, and adjust the docstring.
+        (command_loop_1, read_char, Finput_pending, Fdiscard_input,
+        quit_throw_to_read_char, init_keyboard): Change to use
+        unread_command_events, with the new semantics.
+        * lread.c (read_char): Same.
+        * minibuf.c (temp_echo_area_glyphs): Same.
+        * xterm.c (unread_command_event): Remove external declaration for
+        this; it is only used by obsolete code.
+
+        * Makefile.in: Some makes can't handle comments in the middle of
+        commands; move them to before the whole rule.
+
+1993-01-21  Jim Blandy  (jimb@totoro.cs.oberlin.edu)
+
+        * keyboard.c (make_lispy_event): When handling a mouse click event
+        on a window, change x and y from screen coordinates to window
+        coordinates even when the click isn't in the text area.
+
+        * xterm.c (x_scrollbar_create): Remove code which asks for
+        EastGravity for windows; Emacs can't correctly deal with them
+        moving around unexpectedly.
+
+        * xterm.c (XTread_socket): Minor reformatting.
+
+        * xterm.c (x_set_window_size): Always mark the frame garbaged.
+
+        * window.c (Vmouse_window): Variable removed; it can't be handled
+        properly without race conditions, and the events give you all the
+        information you need anyway.
+        (syms_of_window): Remove DEFVAR.
+        * callint.c (Fcall_interactively): Change the `@' spec to select
+        the window of the first parameterized event in the key sequence
+        which invoked the command, instead of using Vmouse_window, which
+        isn't even updated anymore.  Adjust the documentation
+        accordingly.
+
+1993-01-20  Jim Blandy  (jimb@totoro.cs.oberlin.edu)
+
+        * xterm.c (x_scrollbar_create): Set the scrollbars to use
+        EastGravity.
+
+        * keyboard.c (make_lispy_event): Deal with button releases with no
+        stored down-going position.  Make sure we always store a Qnil in
+        the right button_down_location element after using it.
+
+1993-01-19  Jim Blandy  (jimb@totoro.cs.oberlin.edu)
+
+        * frame.c (Fdelete_frame): Clear the frame's display after calling
+        the window-system-dependent frame destruction routine.  We
+        no longer need to pass the display as a separate argument to
+        x_destroy_window.
+        * xterm.c (x_destroy_window): Put the code which clears out f's
+        display here, right after we free the storage it points to.  Put
+        everything, including the code which clears x_focus_frame and
+        x_highlight_frame, inside the BLOCK/UNBLOCK_INPUT pair.
+
+        * dispnew.c (Fredraw_display): Undo change of Jan 12; redraw only
+        frames whose garbaged flag is set.  The change to
+        FRAME_SAMPLE_VISIBILITY on Jan 14 should address the problem better.
+
+        keyboard.c (read_char_menu_prompt): Test HAVE_X_WINDOWS, not
+        HAVE_X_WINDOW.
+
+        The CPP symbol indicating whether or not we have mouse menu
+        support under X Windows is HAVE_X_MENU, not not NO_X_MENU.
+        * emacs.c (main): Test HAVE_X_MENU, instead of NO_X_MENU.
+        * keyboard.c (read_char_menu_prompt): Same.
+        * ymakefile: Same.
+
+        * keyboard.c (read_char, read_char_menu_prompt): Use the
+        EVENT_HAS_PARAMETERS macro from keyboard.h, instead of writing it
+        out.
+
+        * keyboard.c (read_char_menu_prompt): Doc fix.
+
+        * keyboard.c (read_char_menu_prompt): Fix test for no menus;
+        comparing name to Qnil doesn't work if we are called with no maps.
+
+        * keymap.c (Fdefine_key): Call Fkey_description to make the string
+        to use in the error message.
+
+1993-01-18  Roland McGrath  (roland@churchy.gnu.ai.mit.edu)

+
+1993-01-16  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)
+
+        * xterm.c (x_window_to_scrollbar): Search frames'
+        condemned_scrollbars list as well; input might arrive during
+        redisplay.
+        (x_scrollbar_report_motion): Don't forget to BLOCK_INPUT.
+        (XTjudge_scrollbars): Clear the condemned scrollbar list before
+        traversing it, so we don't try to process an event on a scrollbar
+        we've killed.
+

+        * xterm.c (x_scrollbar_create): Include PointerMotionHintMask in
+        the event mask for scrollbars.
+
+        * dispnew.c (Fredraw_display): DEFUN was missing a closing paren.
+
+        * term.c (set_vertical_scrollbar_hook, condemn_scrollbars_hook,
+        redeem_scrollbar_hook, judge_scrollbars_hook): Removed dumbo
+        "externs" from these.  They're supposed to be real definitions.
+
+        * .gdbinit: Add "-geometry +0+0" to default args.
+        (xscrollbar): New command.
+
+        Make scrollbar structures into lisp objects, so that they can be
+        GC'd; this allows windows and scrollbars can refer to each other
+        without worrying about dangling pointers.
+        * xterm.h (struct x_display): vertical_scrollbars and
+        judge_timestamp members deleted.
+        (struct scrollbar): Redesigned to be a template for a Lisp_Vector.
+        (SCROLLBAR_VEC_SIZE, XSCROLLBAR, SCROLLBAR_PACK, SCROLLBAR_UNPACK,
+        SCROLLBAR_X_WINDOW, SET_SCROLLBAR_X_WINDOW,
+        VERTICAL_SCROLLBAR_INSIDE_WIDTH, VERTICAL_SCROLLBAR_TOP_RANGE,
+        VERTICAL_SCROLLBAR_INSIDE_HEIGHT, VERTICAL_SCROLLBAR_MIN_HANDLE):
+        New macros, to help deal with the lispy structures, and deal with
+        the graphics.
+        * frame.h (WINDOW_VERTICAL_SCROLLBAR): Macro deleted.
+        (struct frame): New fields `scrollbars' and
+        `condemned_scrollbars', for use by the scrollbar implementation.
+        [MULTI_FRAME and not MULTI_FRAME] (FRAME_SCROLLBARS,
+        FRAME_CONDEMNED_SCROLLBARS): Accessors for the new field.
+        * window.h (struct window): Doc fix for vertical_scrollbar field.
+        * frame.c (make_frame): Initialize the `scrollbars' and
+        `condemned_scrollbars' fields of the new frame.
+        * alloc.c (mark_object): Mark the `scrollbars' and
+        `condemned_scrollbars' slots of frames.
+        * xterm.c (x_window_to_scrollbar): Scrollbars are chained on
+        frames' scrollbar field, not their x.display->vertical_scrollbars
+        field.
+        (x_scrollbar_create, x_scrollbar_set_handle, x_scrollbar_move,
+        x_scrollbar_remove, XTset_vertical_scrollbar,
+        XTcondemn_scrollbars, XTredeem_scrollbar, XTjudge_scrollbars,
+        x_scrollbar_expose, x_scrollbar_handle_click,
+        x_scrollbar_handle_motion): Substantially rewritten to correct
+        typos and brainos, and to accomodate the lispy structures.
+
+        * xterm.c (x_scrollbar_background_expose): Function deleted; we
+        don't want anything in the background there after all.
+        (XTread_socket): Don't call x_scrollbar_background_expose.  We
+        don't care.
+
+        * frame.h (FRAME_SAMPLE_VISIBILITY): Make sure frame is marked as
+        garbaged whenever it goes from invisible to visible.
+        * dispextern.h (frame_garbaged): Move extern declaration from here...
+        * frame.h (frame_garbaged): ... to here.  The FRAME_SAMPLE_VISIBILITY
+        macro uses it now, and this seems to be just as modular.  Make a
+        new page, just for this and message_buf_print.
+        (struct frame): Doc fix for the `visible' field.
+        * process.c: #include "frame.h" instead of "dispextern.h"; the
+        only thing we care about from it is the frame_garbaged
+        declaration.
+        * ymakefile: Note dependency change.
+
+        * xfns.c (Fx_create_frame): After mapping the frame, call
+        SET_FRAME_GARBAGED, not just plain FRAME_GARBAGED.
+
+        * window.c (window_internal_width): New function, which accounts
+        for scrollbars if present.
+        * lisp.h (window_internal_height, window_internal_width): Add
+        extern declarations for these.
+        * dispnew.c (direct_output_for_insert, direct_output_forward_char,
+        buffer_posn_from_coords): Use window_internal_width instead of
+        writing out its definition.
+        * indent.c (compute_motion): Doc fix; mention scrollbars and
+        window_internal_width.
+        (pos_tab_offset, Fvertical_motion): Use window_internal_width
+        instead of writing it out.
+        * window.c (Fpos_visible_in_window_p, Fwindow_width, Fscroll_left,
+        Fscroll_right): Same.
+        * xdisp.c (redisplay, try_window, try_window_id,
+        display_text_line): Same.
+
+        * xdisp.c (display_string): Add new variable `f', to be W's
+        frame.  Use it to set desired_glyphs, and to get the frame's width
+        to decide whether or not to draw vertical bars.
+
+        * xdisp.c (display_text_line): If we're using vertical scrollbars,
+        don't draw the vertical bars separating side-by-side windows.
+        (display_string): Same thing.  Draw spaces to fill in the part of
+        the mode line that is under the scrollbar in partial-width
+        windows.
+
+        * xfns.c (Qvertical_scrollbars): New symbol.  Use it as the name
+        of the parameter which decides whether or not the frame has
+        scrollbars, instead of Qvertical_scrollbar.
+        (Fx_create_frame): Adjusted accordingly.
+        (syms_of_xfns): Initialize and staticpro Qvertical_scrollbars.
+        (x_set_vertical_scrollbar): Renamed to x_set_vertical_scrollbars.
+        (x_frame_parms): Adjusted accordingly.
+
+        * xterm.h (CHAR_TO_PIXEL_WIDTH, CHAR_TO_PIXEL_HEIGHT,
+        PIXEL_TO_CHAR_WIDTH, PIXEL_TO_CHAR_HEIGHT): Rewritten, using:
+        (CHAR_TO_PIXEL_ROW, CHAR_TO_PIXEL_COL, PIXEL_TO_CHAR_ROW,
+        PIXEL_TO_CHAR_COL): New macros.
+        * xfns.c [not HAVE_X11] (Fx_create_frame): Use the
+        PIXEL_TO_CHAR_{HEIGHT,WIDTH} macros to figure the frame's
+        character size, and the CHAR_TO_PIXEL* macros for vice versa.
+        * xterm.c (XTwrite_glyphs, XTclear_end_of_line, stufflines,
+        scraplines, dumprectangle, pixel_to_glyph_coords, x_draw_box,
+        clear_cursor, x_display_bar_cursor, x_draw_single_glyph,
+        x_set_mouse_position): Use the CHAR_TO_PIXEL_* macros.
+
+        * xterm.c (x_wm_set_size_hint): The max_width and max_height
+        members of the size_hints are expressed in pixels, not columns.
+
+        * xterm.c (x_set_window_size): Remove ibw var; it's not used.
+        Set FRAME_WIDTH (f) to cols instead of rows.  Duh.
+
+        * xterm.c (pixel_to_glyph_coords): Properly set *bounds to the
+        character cell bounding the position, even when the position is
+        off the frame.
+
+        * xfns.c (x_set_name): To request that the modelines be redrawn,
+        execute the statement "update_mode_lines = 1;" instead of the
+        silly statement "update_mode_lines;".
+
+        * xfns.c (x_set_vertical_scrollbars): Don't try to set the
+        X window's size if the frame's X window hasn't been created yet.
+
+        * xfns.c (x_figure_window_size): Set the frame's
+        vertical_scrollbar_extra field before trying to calculate its
+        pixel dimensions.
+
+        * xfns.c (x_window): When calling x_implicitly_set_name for the
+        sake of drawing the name for the first time, remember to clear and
+        set the frame's explicit_name member as well as its name member.
+        (Fx_create_frame): Set the frame's explicit_name member if the
+        user specified the name explicitly.
+
+        * xdisp.c (display_text_line): Use the usable internal width of
+        the window, as calculated above, as the limit on the length of the
+        overlay arrow's image, rather than using the window's width field,
+        less one.
+
+        * xdisp.c (redisplay): Call condemn_scrollbars_hook and
+        judge_scrollbars_hook whenever they are set, not just when the
+        frame has vertical scrollbars.
+
+        * termhooks.h (mouse_position_hook): Doc fix.
+        (set_vertical_scrollbar_hook): This doesn't return anything any
+        more, and doesn't take a struct scrollbar * argument any more.
+        (condemn_scrollbars_hook, redeem_scrollbar_hook,
+        judge_scrollbars_hook): Doc fixes.
+        * term.c (mouse_position_hook): Doc fix.
+        (set_vertical_scrollbar_hook): This doesn't return
+        anything any more.  Doc fixes.
+        * keyboard.c (kbd_buffer_get_event): Receive the scrollbar's
+        window from *mouse_position_hook and pass it to
+        make_lispy_movement, instead of working with a pointer to a struct
+        scrollbar.
+        (make_lispy_event): We don't need a window_from_scrollbar function
+        anymore; we are given the window directly in *EVENT.
+        Unify the code which generates
+        text-area mouse clicks and scrollbar clicks; use the same code to
+        distinguish clicks from drags on the scrollbar as in the text area.
+        Distinguish clicks from drags by storing a copy of the lispy
+        position list returned as part of the event.
+        (button_down_location): Make this a lisp vector, rather than an
+        array of random structures.
+        (struct mouse_position): Remove this; it's been replaced by a lisp
+        list.
+        (make_lispy_movement): Accept the scrollbar's window as a
+        parameter, rather than the scrollbar itself.
+        If FRAME is zero, assume that the other arguments are garbage.
+        (syms_of_keyboard): No need to staticpro each window of
+        button_down_location now; just initialize and staticpro it.
+        * window.c (window_from_scrollbar): Function deleted; no longer
+        needed.
+        * xdisp.c (redisplay_window): Just pass the window to
+        set_vertical_scrollbar hook; don't pass the scrollbar object too.
+        * xterm.c (XTmouse_position): Don't return a pointer to the
+        scrollbar for scrollbar motion; instead, return the scrollbar's
+        window.
+
+        * xterm.c (XTmouse_position): Entirely rewritten, using
+        XTranslateCoordinates.  Call x_scrollbar_report_motion to handle
+        scrollbar movement events.
+        (x_scrollbar_report_motion): New function, to help out
+        XTmouse_position.
+
+        * keyboard.c (apply_modifiers): Don't assume that the Qevent_kind
+        property of BASE is set when we first create the new modified
+        symbol.  Check that the Qevent_kind property is properly set each
+        time we return any symbol.
+
+        * termhooks.h (struct input_event): Replace the frame member with
+        a Lisp_Object member by the name of frame_or_window.  Doc fixes.
+        Remove the scrollbar member; instead, use frame_or_window to hold the
+        window whose scrollbar was clicked.
+        * keyboard.c (kbd_buffer_store_event, kbd_buffer_get_event,
+        make_lispy_event): Adjust references to frame member of struct
+        input_event to use frame_or_window now.
+        * xterm.c (construct_mouse_click, XTread_socket): Same.
+
+        * xterm.c (last_mouse_bar, last_mouse_bar_frame, last_mouse_part,
+        last_mouse_scroll_range_start, last_mouse_scroll_range_end):
+        Replaced with...
+        (last_mouse_scrollbar): New variable.
+        (note_mouse_movement): Clear last_mouse_scrollbar when we have
+        receieved a new motion.
+        (syms_of_xterm): Staticpro last_mouse_scrollbar.
+
+        * xterm.c (note_mouse_position): Renamed to note_mouse_movement,
+        because that's what it really does.
+        (x_scrollbar_handle_motion): Renamed to x_scrollbar_note_movement,
+        for consistency.
+        (XTread_socket): Adjusted.
+
+        * xterm.c (XTset_scrollbar): Renamed to XTset_vertical_scrollbar.
+        (x_term_init): Adjusted.
+
+        * keyboard.c (kbd_buffer_frames): Renamed to
+        kbd_buffer_frame_or_window, and made to exist even when
+        MULTI_FRAME isn't defined; single-frame systems might have
+        scrollbars.  Use it to GCPRO the frame_or_window field in the
+        event queue.
+        (kbd_buffer_store_event, kbd_buffer_get_event,
+        stuff_buffered_input): Set and clear the
+        appropriate element of kbd_buffer_frame_or_window, whether or not
+        MULTI_FRAME is #defined.
+        (read_avail_input): When reading characters directly from stdin,
+        set the frame_or_window field of the event appropriately,
+        depending on whether or not MULTI_FRAME is #defined.
+        (Fdiscard_input, init_keyboard): Zap kbd_buffer_frame_or_window,
+        not kbd_buffer_frames.
+        (syms_of_keyboard): Initialize and staticpro
+        kbd_buffer_frame_or_window, whether or not MULTI_FRAME is
+        #defined.
+
+        * keyboard.c (head_table): Make Qscrollbar_movement have a
+        Qevent_kind property of Qmouse_movement, not Qscrollbar_movement.
+
+        * keyboard.c (read_key_sequence): If we decide to throw away a
+        mouse event which has prefix symbols (`mode-line',
+        `vertical-scrollbar', etcetera), remember that we may have to
+        unwind two characters, not just one.
+
+        * keyboard.c (read_key_sequence): Doc fixes.
+
+        * keyboard.c (kbd_buffer_store_event): Fix reversed sense of test
+        for focus redirection.
+
+        * keyboard.c (read_char): Don't echo mouse movements.
+
+        * emacs.c (shut_down_emacs): New function.
+        (fatal_error_signal, Fkill_emacs): Call it, instead of writing it out.
+        * xterm.c (x_connection_closed): Call shut_down_emacs instead of
+        Fkill_emacs; the latter will try to perform operations on the X
+        server and die a horrible death.
+        * lisp.h (shut_down_emacs): Add extern declaration for it.
+
+        * xterm.c (x_error_quitter): Move the abort call to after we print
+        the error message.  No harm in that.
+
+        * xdisp.c (echo_area_display): Move the assignment of f and the
+        check for visibility out of the "#ifdef MULTI_FRAME" clause; they
+        should work under any circumstances.
+
+        * xdisp.c (redisplay_window): If we're not going to redisplay this
+        window because it's a minibuffer whose contents have already been
+        updated, go ahead and jump to the scrollbar refreshing code
+        anyway; they still need to be updated.  Initialize opoint, so it's
+        known to be valid when we jump.  Calculate the scrollbar settings
+        properly for minibuffers, no matter what they are displaying at
+        the time.
+
+        * xdisp.c (redisplay_windows): Don't restore the current buffer
+        and its point before refreshing the scrollbars; we need the buffer
+        accurate.
+
+1993-01-12  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+        * print.c (float_to_string): Add final 0 if text ends with decimal pt.
+
+        * dispnew.c (Fredraw_display): Redraw all visible frames.
+        Make the non-multi-frame version interactive.
+
+1993-01-11  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+        * fileio.c (Fset_default_file_modes, Fdefault_file_modes):
+        Renamed from Fset_umask and Fumask; sense of arg is reversed.
+        (Fwrite_region): Doc fix.
+
+1993-01-10  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+        * print.c (float_to_string): Add `.0' at end if needed.
+
+        * lread.c (Fload): If warn that .elc file is older, inhibit
+        the ordinary message that would follow.
+
+1993-01-09  Jim Blandy  (jimb@totoro.cs.oberlin.edu)
+
+        * fileio.c (Fdo_auto_save): Add CURRENT_ONLY argument, as
+        described in doc string.
+
+1993-01-08  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+        * fns.c (Frandom): Change arg name.
+
+        * editfns.c: Doc fixes.
+
+1993-01-07  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+        * unexhp9k800.c (unexec): Don't call exit, just return.
+
+1993-01-07  Jim Blandy  (jimb@totoro.cs.oberlin.edu)

+
+        * xfns.c (Fx_get_resource): Add CLASS argument, to give class of
+        ATTRIBUTE.
+        [not HAVE_X11]: Change definition of Fx_get_resource macro
+        accordingly.
+        (x_get_arg): Add CLASS argument, to give the class of ATTRIBUTE.
+        Pass it along to Fx_get_resource.
+        (x_figure_window_size, x_icon): Pass new argument to x_get_arg.
+        (x_default_parameter): Add XCLASS argument, to give the class of
+        XPROP.  Pass it along to x_get_arg.
+        (Fx_create_frame): Pass new args to x_get_arg and
+        x_default_parameter.
+
+        * xfns.c (Fx_create_frame): Use the same resource names and
+        classes as xterm and Emacs 18.
+
+1993-01-03  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+        * xfns.c (Fx_get_resource): Use EMACS_CLASS to make class_key
+        even if SUBCLASS is specified.  I don't know whether that is
+        right, but that's what the doc says.
+        Cosmetic changes in arg names and doc string.
+
+1992-12-29  Roland McGrath  (roland@geech.gnu.ai.mit.edu)
+
+        * ralloc.c: [! emacs] [HAVE_CONFIG_H]: #include "config.h"

+        #ifdef MULTI_FRAME.
+
+        * frame.h (struct frame): New fields `can_have_scrollbars' and

+        CHAR_TO_PIXEL_WIDTH, CHAR_TO_PIXEL_HEIGHT, PIXEL_TO_CHAR_WIDTH,
+        PIXEL_TO_CHAR_HEIGHT): New accessors and macros.
+        * frame.c (make_frame): Initialize the `can_have_scrollbars' and
+        `has_vertical_scrollbars' fields of the frame.
+        * term.c (term_init): Note that TERMCAP terminals don't support
+        scrollbars.
+        (mouse_position_hook): Document new args.
+        (set_vertical_scrollbar_hook, condemn_scrollbars_hook,
+        redeem_scrollbar_hook, judge_scrollbars_hook): New hooks.
+        * termhooks.h: Declare and document them.
+        (enum scrollbar_part): New type.
+        (struct input_event): Describe the new form of the scrollbar_click
+        event type.  Change `part' from a Lisp_Object to an enum
+        scrollbar_part.  Add a new field `scrollbar'.
+        * keyboard.c (kbd_buffer_get_event): Pass appropriate new
+        parameters to *mouse_position_hook, and make_lispy_movement.

+
+        * xterm.c (x_set_mouse_position): Clip mouse position to be within
+        frame.
+
+        * xterm.c: Adjust the first line of each page to have a reasonable

+
+        * xterm.c (x_do_pending_expose): Declare this routine only if

+        hollow at the appropriate times, even in titleless windows.
+        * xterm.c (x_focus_event_frame): New variable.
+        (XTread_socket): When we receive a FocusIn event that's not
+        NotifyPointer, record the frame in x_focus_event_frame.  When we
+        receive a FocusOut event that's not NotifyPointer, clear it.  When

+        have focus.
+
+        * xterm.c (XTread_socket): Remove special code in EnterNotify case

+
+        Change the meaning of focus redirection to make switching windows
+        work properly.  Fredirect_frame_focus has the details.
+        * frame.h (focus_frame): Doc fix.
+        [not MULTI_FRAME] (FRAME_FOCUS_FRAME): Make this Qnil, which
+        indicates no focus redirection, instead of zero, which is
+        selected_frame.
+        * frame.c (make_frame): Initialize f->focus_frame to Qnil, rather
+        than making it point to frame itself.
+        (Fselect_frame): If changing the selected frame from FOO to BAR,
+        make all redirections to FOO shift to BAR as well.  Doc fix.
+        (Fredirect_frame_focus): Doc fix.  Accept nil as a valid

+        * window.c (Fset_window_configuration): Don't restore the frame's
+        focus redirection if the target frame is now dead.
+
+        * ymakefile (ralloc.o): This no longer depends on xterm.h.
+
+        * ymakefile (all, xemacs): We build an executable called `emacs' now,
+        not `xemacs'.
+        * Makefile.in (distclean, xemacs, doxemacs): Same.
+
+        * xterm.h (PIXEL_WIDTH, PIXEL_HEIGHT): Change name of parameter

+
+1992-12-18  Jim Blandy  (jimb@totoro.cs.oberlin.edu)
+
+        * keyboard.c (kbd_buffer_frames): New vector, to GCPRO frames in

+        (kbd_buffer_get_event): When we remove an event from kbd_buffer,
+        make sure to set the corresponding element of kbd_buffer_frames to
+        Qnil, to allow the frame to get GC'd.
+        (Fdiscard_input, init_keyboard): Clear all elements of
+        kbd_buffer_frames to nil.
+        (syms_of_keyboard): Create and staticpro kbd_buffer_frames.
+
+        * xterm.c (x_error_quitter): Just abort, so we can look at the

+
+1992-12-17  Jim Blandy  (jimb@totoro.cs.oberlin.edu)
+
+        * buffer.c (Frename_buffer): Set update_mode_lines.
+
+1992-12-14  Jim Blandy  (jimb@totoro.cs.oberlin.edu)
+
+        * scroll.c (do_scrolling): When bcopying the max_ascent field from
+        current_frame to temp_frame, remember that max_ascent is an array
+        of shorts, not ints.
+
+        It's a pain to remember that you can't assign to FRAME->visible.
+        Let's change all references to the `visible' member of struct
+        frame to use the accessor macros, and then write a setter for the
+        `visible' field that does the right thing.
+        * frame.h (FRAME_VISIBLE_P): Make this not an l-value.
+        (FRAME_SET_VISIBLE): New macro.
+        * frame.c (make_terminal_frame, Fdelete_frame): Use FRAME_SET_VISIBLE.
+        (Fframe_visible_p, Fvisible_frame_list): Use FRAME_VISIBLE_P and

+
+        * ymakefile (CFLAGS): #define HAVE_CONFIG_H too.

+        * Makefile.in (distclean): Don't delete machine.h or system.h;
+        they don't exist anymore.
+
+        * Makefile.in (distclean): Don't delete autosave or backup files.

+        and backup files too.
+
+1992-12-11  Jim Blandy  (jimb@totoro.cs.oberlin.edu)
+
+        * search.c (Fskip_chars_forward, Fskip_chars_backward): Return the
+        distance traveled.
+        (skip_chars): Return the distance traveled, as a Lisp_Object.
+
+        * macros.c (Fend_kbd_macro): Don't use XFASTINT to check if arg is
+        negative; XFASTINT only works on values known to be positive.
+        (Fexecute_kbd_macro): Check QUIT in the repetition loop.  If the
+        macro is null, no characters are actually being read, so this
+        matters.
+
+        * Makefile.in (srcdir): New variable, not fully implemented.
+        (xmakefile): Turn -g and -O in CFLAGS into C_DEBUG_SWITCH and
+        C_OPTIMIZE_SWITCH in C_SWITCH_SITE's definition.  Delete junk.cpp
+        when done.
+        * ymakefile (archlib): Variable definition deleted.  Run programs
+        from ../lib-src directly, or use ${archlibdir}.
+        (${etc}DOC): Run make-docfile from ${libsrc}, not ${archlib}.
+        (${archlib}make-docfile, ${archlib}emacstool): Use ${libsrc}, not

+
+        * ymakefile (lisp): Don't include version.el in this list.
+
+        Give subprocess creation a way to find a valid current directory
+        for subprocesses when the buffer's default-directory is a handled
+        name.
+        * fileio.c (Funhandled_file_name_directory): New function.
+        (Qunhandled_file_name_directory): New file-name-handler operation.
+        (syms_of_fileio): Defsubr Sunhandled_file_name_directory, and
+        initialize and staticpro Qunhandled_file_name_directory.
+        * callproc.c (Fcall_process): Call Funhandled_file_name_directory
+        on the buffer's default directory.  Do it earlier in the function
+        so there's less to GCPRO.
+        * process.c (create_process): Don't check the validity of the 
+        buffer's default directory here...
+        (Fstart_process): Instead, do it here; if we call
+        Funhandled_file_name_directory here, there's less GCPROing to do.
+
+        * callproc.c (Fcall_process_region): Return the value returned by
+        Fcall_process.
+
+        * fileio.c (find_file_handler): Rename this to
+        Ffind_file_name_handler, and make it visible to lisp.  Add a QUIT
+        to the loop which scans file-name-handler-alist.  All uses
+        changed.
+        (syms_of_fileio): Mention this new function in the docstring for
+        Vfile_name_handler_alist.  defsubr Sfind_file_name_handler.
+        * lisp.h (Ffind_file_name_handler): Added extern declaration.
+        * dired.c: All uses of find_file_handler changed here too.
+
+        * fileio.c (syms_of_fileio): Add staticpros for Qexpand_file_name,
+        Qdirectory_file_name, Qfile_name_directory,
+        Qfile_name_nondirectory, Qfile_name_as_directory.
+
+1992-12-07  Jim Blandy  (jimb@totoro.cs.oberlin.edu)
+
+        * window.c (Fset_window_configuration): If we're restoring the
+        configuration of a dead frame, don't bother rebuilding its window
+        tree, restoring its focus redirection, or temporarily resizing it
+        to fit the saved window configuration.  If the frame which was
+        selected when the configuration was captured is now dead, don't
+        try to select it.
+
+        * frame.c (Fdelete_frame): Delete all the windows in the frame's
+        window tree, using delete_all_subwindows.
+        * window.c (delete_all_subwindows): Don't make this static
+        anymore.
+
+1992-12-03  Jim Blandy  (jimb@totoro.cs.oberlin.edu)
+
+        Make sure that frames' visible flag only changes at acceptable
+        times.  See FRAME_SAMPLE_VISIBILITY's comments for details.
+        * frame.h (struct frame): New fields called async_visible and
+        async_iconified.
+        (FRAME_SAMPLE_VISIBILITY): New macro, with MULTI_FRAME and
+        non-MULTI_FRAME definitions.
+        * xdisp.c (redisplay): Call FRAME_SAMPLE_VISIBILITY to set the
+        visible and iconified flags appropriately for each frame.
+        (message1): Call FRAME_SAMPLE_VISIBILITY to set the visible and
+        iconified flags for the minibuffer frame.
+        * frame.c (make_frame): Initialize async_visible and
+        async_iconified properly.
+        * xfns.c (Fx_create_frame): Initialize f->async_visible too.
+        * xterm.c (XTread_socket): When we get MapNotify, UnmapNotify,
+        Expose, ExposeWindow, or UnmapWindow, set f->async_visible, not
+        f->visible.
+        (x_do_pending_expose, x_raise_frame, x_lower_frame,
+        x_make_frame_invisible, x_make_frame_visible, x_iconify_frame):

+        (Fdiscard_input): Use cast to keep GCC from complaining about the
+        assignment of kbd_store_ptr to kbd_fetch_ptr.
+
+        * xdisp.c (redisplay): Use FOR_EACH_FRAME to apply
+        redisplay_windows to the root window of each frame.  This makes a
+        #ifdef MULTI_FRAME unneeded, but it also means we recompute
+        buffer_shared from scratch even on non-MULTI_FRAME configurations.
+        Don't skip elements of Vframe_list that aren't frames; go ahead
+        and crash here.
+
+        * xdisp.c (redisplay): Remove #ifdef MULTI_FRAME around the code
+        which updates separate minibuffer frames specially; there's
+        nothing there that won't work on a single-frame configuration.
+
+        * dispextern.h (struct frame_glyphs): Doc fix.
+
+1992-12-02  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)
+
+        * dispnew.c: Remove dyked-out copy of safe_bcopy.

+1992-12-01  Jim Blandy  (jimb@totoro.cs.oberlin.edu)
+
+        * process.c (wait_reading_process_input): Doc fix.

+1992-11-26  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+        * next.h: Copy changes from 18.59:

+        (BIG_ENDIAN): Define only if __BIG_ENDIAN__.
+        (m68000, COMPILER_REGISTER_BUG): Defs deleted.
+        (SIGN_EXTEND_CHAR, LIB_X11_LIB, NO_T_CHARS_DEFINES, UNEXEC): Defined.
+        (LIBS_DEBUG, LIB_GCC, C_SWITCH_MACHINE, ORDINARY_LINK): Defined.
+        (TEXT_START, TEXT_END, DATA_END, LD_SWITCH_MACHINE): Defined.

+        (environ): Define as _environ.
+
+1992-11-25  Jim Blandy  (jimb@totoro.cs.oberlin.edu)
+
+        * doc.c (store_function_docstring): New function, made from part
+        of Fsnarf_documentation, which handles docstrings for macros
+        properly.
+        (Fsnarf_documentation): Call store_function_docstring.
+
+        * data.c (indirect_function): Delete unused argument ERROR.

+1992-11-21  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+        * s/sol2.h (LD_SWITCH_SYSTEM): Make alternate version for GCC.
+
+1992-11-19  Jim Blandy  (jimb@totoro.cs.oberlin.edu)
+
+        * m/sparc.h: Don't include <sys/param.h> here; that screws up the
+        xmakefile.  Instead, include it in getloadavg.c, which is the only
+        place that uses LOAD_AVE_CVT, which is the only reason
+        <sys/param.h> was here in the first place.
+
+1992-11-15  Jim Blandy  (jimb@totoro.cs.oberlin.edu)
+
+        * dispnew.c [not MULTI_FRAME] (Fredraw_display): Pass the correct

+
+        * undo.c (Fprimitive_undo): Remove whitespace in front of #ifdef
+        and #endif.

+        * systty.h: Doc fix.
+        
+        * systty.h, process.c, buffer.h, callproc.c, sysdep.c, dired.c:
+        Added VMS changes from Roland Roberts.
+        * vmspaths.h: New version from Roland Roberts.
+
+        * xdisp.c (display_string): Use w's buffer's value of
+        tab-width to display the string, instead of the current buffer's,
+        which could be anything.
+
+        * s/sol2.h (LD_SWITCH_SYSTEM): Add -R option.
+
+        * process.c (read_process_output): Save, widen, insert the process
+        output, and then restore the restriction if inserting text outside
+        the visible region.
+
+1992-11-14  Jim Blandy  (jimb@totoro.cs.oberlin.edu)
+
+        * buffer.c (Ferase_buffer): Doc fix.
+
+        * dispnew.c (safe_bcopy): Use the right terminating condition in
+        the loop which uses multiple bcopy calls to transfer a block to an
+        overlapping higher block.
+
+1992-11-13  Jim Blandy  (jimb@totoro.cs.oberlin.edu)
+
+        * process.c (Fstart_process): Establish an unwind-protect to
+        remove PROC from the process list if an error occurs while
+        starting it.
+        (start_process_unwind): New function to help with that.
+        (create_process): There's no need to explicitly call
+        remove_process if the fork fails; the record_unwind_protect in
+        Fstart_process will take care of it.
+
+        * commands.h (unread_command_event): Doc fix.
+
+        Don't ever throw away switch-frame events.
+        * lread.c: #include "keyboard.h".
+        (Fread_char, Fread_char_exclusive): Don't signal an
+        error for or throw away switch-frame events; instead, put them off
+        until after we've found a character we can respond to.
+        * commands.h (unread_switch_frame): Declare this extern.
+        * keyboard.c (unread_switch_frame): Don't declare this static.
+        * ymakefile (lread.o): Note that this depends on keyboard.h.
+
+        * keyboard.c (Vlast_event_frame): Doc fix.
+
+        * process.c (wait_reading_process_input): Test the C preprocessor
+        symbol "ultrix", not "__ultrix__" to see if we should ignore
+        ENOMEM errors from select.
+
+        * fileio.c (Fexpand_file_name): Don't fiddle with "/." if it's the
+        entire string.
+
+        * buffer.c (Fbury_buffer): Make this behave as in 18.59, although
+        that behavior is very odd - only remove the buffer from the
+        selected window if BUFFER was nil or omitted.
+
+        * keyboard.c (read_char): Write composite events to the dribble
+        file properly.
+
+        * keyboard.c (init_keyboard): Initialize Vlast_event_frame to
+        Qnil, rather than the selected frame.
+
+        * mem-limits.h [DATA_SEG_BITS] (EXCEEDS_LISP_PTR): Remember to
+        remove DATA_SEG_BITS from the pointer before testing if the
+        pointer fits in VALBITS.
+
+        * Makefile.in (doxemacs, dotemacs): Explicitly pass along the CC
+        variable in these rules, just as in the `doall' rule.
+
+        * ralloc.c (relocate_some_blocs): Handle BLOC == NIL_BLOC.
+        (free_bloc): This can now be simplified.
+
+        * ralloc.c (r_alloc_sbrk): When we allocate new space for the
+        malloc heap, zero it out even if we don't have any blocs in the
+        free list.
+
+1992-11-12  Jim Blandy  (jimb@totoro.cs.oberlin.edu)
+
+        * process.c (process_send_signal): On systems which have both
+        the TIOCGETC and TCGETA ioctls, just use the former.
+
+        * xselect.c (Fx_get_cut_buffer): Correct check for buf_num in
+        range.
+
+        * xselect.c (Fx_get_cut_buffer, Fx_set_cut_buffer): Fix error
+        message format; use NUM_CUT_BUFFERS instead of literal 7.
+
+        * keyboard.c (lispy_modifier_list): Added sanity check before
+        indexing into modifier_symbols.
+
+        * keyboard.c (add_command_key): When copying the contents of the
+        old this_command_keys to new_keys, remember to multiply size by
+        sizeof (Lisp_Object) to get the amount we really need to copy.
+
+        Rename unread_command_char to unread_command_event; it has
+        subtly different semantics now, and we should use
+        `make-obsolete-variable' to warn people.
+        * command.h (unread_command_char): Change name in extern declaration.
+        * keyboard.c (unread_command_char): Rename.
+        (command_loop_1, read_char, Finput_pending, Fdiscard_input,
+        quit_throw_to_read_char, init_keyboard, syms_of_keyboard): Change
+        references.
+        * lread.c (Fread_char): Change reference.
+        * minibuf.c (temp_echo_area_glyphs): Change reference to
+        unread_command_char to unread_command_event.
+        * xfns.c (unread_command_char): Change name in extern declaration
+        to unread_command_event.
+
+1992-11-11  Jim Blandy  (jimb@totoro.cs.oberlin.edu)
+
+        * m/pmax.h: Don't define SYSTEM_MALLOC; this was only necessary
+        for Ultrix version 4.1, and the current version is 4.3.
+
+        * s/bsd4-2.h, s/bsd4-3.h: #define SIGNALS_VIA_CHARACTERS.
+        * process.c (process_send_signal): Put all the code for sending
+        signals via characters in a #ifdef SIGNALS_VIA_CHARACTERS.  Decide
+        whether to use the Berkeley-style or SYSV-style ioctls by seeing
+        which ioctl commands are #defined.
+
+        * minibuf.c (read_minibuf): If get_minibuffer gives the
+        new minibuffer a nil default directory, find another buffer with a
+        better default directory and use that one's instead.
+
+1992-11-10  Jim Blandy  (jimb@totoro.cs.oberlin.edu)
+
+        * process.c (process_send_signal): Doc fix.
+
+        * keyboard.c (read_key_sequence): Don't use
+        save_excursion_{save,restore} to protect the caller against buffer
+        switches; use Fset_buffer and Fcurrent_buffer; redisplay might
+        change point, and we don't want to undo that.
+
+        * keyboard.c (kbd_buffer_get_event): When checking a mouse
+        movement for a frame switch, don't assume Vlast_event_frame
+        contains a Lisp_Frame object.
+
+1992-11-06  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+        * s/dgux.h (SYSTEM_TYPE): Use berkeley-unix.
+
+1992-11-04  Jim Blandy  (jimb@totoro.cs.oberlin.edu)
+
+        * alloc.c: #include "frame.h" unconditionally.  frame.h does the
+        right thing when MULTI_FRAME isn't defined.
+
+        * Makefile.in: Rearrange dependencies to make sure that xmakefile
+        is built before we try to use it, even using a parallel make.
+
+        Changes for SYSV from Eric Raymond:
+        * process.c [SYSV]: Don't include <termios.h>, <termio.h>, or
+        <fcntl.h>.
+        (process_send_signal): Don't try to send SIGTSTP
+        unless SIGTSTP is defined.
+        * sysdep.c (init_baud_rate) [HAVE_TERMIO, not HAVE_TCATTR]: Use
+        TCGETA, not TIOCGETP.
+        * systime.h [USG] (EMACS_GET_TZ_OFFSET): Assign to *(offset), not
+        (offset).  Don't forget the while corresponding to the do.
+        Include USG in the list of systems that have a tzname array.
+
+        * keyboard.c (read_key_sequence): Removed the
+        replay_sequence_new_buffer label; replay_sequence should be here
+        instead.
+
+        Arrange to get compile-time errors for uses of Lisp_Frame in a
+        non-MULTI_FRAME configuration.
+        * lisp.h [not MULTI_FRAME]: Don't declare the Lisp_Frame tag.
+        * minibuf.c (read_minibuf): Protect call to Fredirect_frame_focus
+        with a #ifdef MULTI_FRAME.
+        * window.c (Fset_window_configuration): Protect call to
+        Fselect_frame with a #ifdef MULTI_FRAME.
+        [not MULTI_FRAME] (Fcurrent_window_configuration): Don't bother
+        setting the window configuration's selected_frame member.
+        * keyboard.c (Vlast_event_frame): Arrange for this to exist iff
+        MULTI_FRAME is defined.
+        [not MULTI_FRAME] (syms_of_keyboard): Don't DEFVAR Vlast_event_frame.
+        [not MULTI_FRAME] (read_char): Don't try to set Vlast_event_frame.
+        [not MULTI_FRAME] (kbd_buffer_store_event): Don't try to set
+        Vlast_event_frame for quit characters.
+        [not MULTI_FRAME] (kbd_buffer_get_event): Don't try to generate
+        switch-frame events.
+
+        * buffer.c (init_buffer): If PWD is accurate, use it instead of
+        calling getwd.
+        #include <sys/types.h> and <sys/stat.h>, for the call to stat.
+
+        Indicate whether an autoload form stands for a keymap or not.
+        * eval.c (Fautoload): Renamed fifth argument TYPE.  Document the
+        fact that (eq TYPE 'keymap) means FUNCTION will become a keymap
+        when loaded.
+        (Fmacroexpand): Instead of assuming that every autoload
+        form with a fifth element is a macro, actually check the fifth
+        element against t and `macro', which are the only values which
+        denote macroness.
+        * keymap.c (get_keymap_1): Don't try to autoload OBJECT's function
+        unless the autoload form indicates that it's a keymap.
+
+1992-11-03  Jim Blandy  (jimb@totoro.cs.oberlin.edu)
+
+        * .gdbinit (mips): New command.
+
+1992-10-31  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+        * fileio.c (Fmake_directory_internal): Renamed from Fmake_directory.
+        Pass nil as third arg to handler.
+        Lisp function `make-directory' is now in files.el.
+
+1992-10-30  Jim Blandy  (jimb@totoro.cs.oberlin.edu)
+
+        Clean up errors due to treating Lisp_Objects like integers.
+        * abbrev.c (Funexpand_abbrev): Just assign the last abbrev's value
+        to val; don't use XSET.  Make sure that the value of the
+        abbrev-symbol is a string.
+        * alloc.c (Frope_elt): Declare arguments to be Lisp_Objects.
+        * buffer.c (reset_buffer): Don't assign to b->save_length as if it
+        were an int; use XFASTINT.
+        * buffer.h (Fbuffer_name, Fget_file_buffer): Added external
+        declarations.
+        * bytecode.c (Fbyte_code): Use EQ to compare string_saved with
+        bytestr.
+        * casefiddle.c (operate_on_word): Declare end to be an int, not a
+        Lisp_Object.
+        * casetab.c (set_case_table): Declare this to be static, and
+        return a Lisp_Object. Add static declaration for this
+        before Fset_case_table and Fset_standard_case_table.
+        (Fset_case_table, Fset_standard_case_table): Return the return
+        value of set_case_table, instead of returning garbage.
+        * commands.h (unread_command_char): Declare this to be a
+        Lisp_Object, not an int.
+        * data.c (Fset): See if current_alist_element points to itself
+        using EQ, not ==.
+        (float_arith_driver): Declare this extern above arith_driver.
+        * dired.c (find_file_handler): Declare this extern.
+        (Ffile_attributes): Use NILP, not == Qnil.
+        * dispextern.h (sit_for): Declare this extern.
+        * doc.c: #include keyboard.h.
+        * floatfns.c (Flog): Don't forget to declare the BASE argument a
+        Lisp_Object.
+        * fns.c: #include keyboard.h.
+        (Fdelete): Check if Fequal returns Qnil, not zero.
+        * frame.c: #include buffer.h.
+        * keyboard.c: #include dispextern.h.
+        (recursive_edit_unwind, command_loop, Fthis_command_keys): Declare
+        these to return Lisp_Objects at the very top of the file, to avoid
+        having them implicitly declared as ints.
+        (echo_char): Use EQ to compare C to help_char.
+        (read_char): Remember to apply XFASTINT to the return value of
+        Flength before using it.  Apply XINT to c when clearing its high
+        bits and meta bits, and when writing it to the dribble file.
+        (read_char_menu_prompt): Use EQ to compare obj with
+        menu_prompt_more_char and its control-character analog.
+        (read_key_sequence): Declare PROMPT to be char *, not a
+        Lisp_Object.  Use the appropriate accessors on keybuf when looking
+        for ASCII function key sequences.
+        * keyboard.h (get_keymap_1, Fkeymapp, reorder_modifiers,
+        Fmouse_click_p, read_char): Add external declarations for these.
+        * keymap.c (Fdefine_key, Flookup_key, describe_map): Don't assume
+        that Flength returns an integer.
+        * lisp.h (Fdefault_boundp, make_float, Ffloat, Fnth, Fcopy_alist,
+        Fmake_byte_code, Fverify_visited_file_modtime, Ffile_exists_p,
+        Fdirectory_file_name, Ffile_name_directory,
+        expand_and_dir_to_file, Ffile_accessible_directory_p, Fbyte_code,
+        Fundo_boundary, truncate_undo_list): Add extern declarations for
+        these.
+        * lread.c (read_char): Add an extern declaration for this,
+        indicating that it returns a Lisp_Object.
+        * minibuf.c (read_minibuf): Use EQ to compare, not ==.
+        (temp_echo_area_glyphs): Use XFASTINT to assign to
+        unread_command_char.
+        * print.c (print): Cast the frame's address to an integer before
+        passing it to sprintf to form the frame's printed form.
+        * process.c: (status_convert): Declare this to return a
+        Lisp_Object at the top of the file.
+        (decode_status): Don't untag XCONS (tem)->cdr before storing it in
+        tem; tem is a Lisp_Object, too.
+        (process_send_signal): Declare this to be static void.  Don't
+        return Qnil; nobody cares.
+        (sigchld_handler): Use XFASTINT to manipulate p->infd.
+        * search.c (Fstore_match_data): Don't assume Flength returns a
+        C integer.
+        * undo.c (record_insert): Use accessors on BEG and LENGTH.
+        (truncate_undo_list): Use NILP, not == Qnil.
+        * window.c (Fwindow_width, Fset_window_hscroll): Use accessors on
+        w->width, w->left, w->hscroll, and arguments.
+        (replace_window): Use EQ, not ==.
+        (Fdelete_window): p->top and p->left are not C integers.
+        (Fnext_window, Fprevious_window): Use EQ, not ==.
+        * window.h (make_window, window_from_coordinates,
+        Fwindow_dedicated_p): Add extern declarations for these.
+        * xdisp.c (redisplay): Use ! EQ to compare the old and new arrow
+        positions, not !=.
+        (mark_window_display_accurate): Barf if WINDOW isn't a window.
+        (display_string): Test buffer_defaults.ctl_arrow using NILP,
+        instead of comparing it with zero.
+        * xfns.c (x_decode_color, Fx_color_display_p): x_screen_planes is
+        an int, not a Lisp_Object.
+        (x_set_mouse_color): Give separate error messages for the
+        different cursors we try to set.
+        (Fx_geometry): Declare STRING to be a Lisp_Object.
+        (Fx_create_frame): No need to use XSET to assign NAME to f->name;
+        they're both Lisp_Objects.
+        (adjust_scrollbars): Use XINT to access w->hscroll.
+        (Fx_open_connection): x_screen_count, x_release, x_screen_height,
+        x_screen_height_mm, x_screen_width, x_screen_width_mm,
+        x_save_under, and x_screen_planes are integers, not Lisp_Objects.
+        (syms_of_xfns): x_mouse_x, x_mouse_y, and mouse_buffer_offset are
+        integers, not Lisp_Objects.
+        * xselect.c (own_selection): selection_type is an X Atom value,
+        not a Lisp_Object.
+        (x_selection_arrival): Declare this static, and add a forward
+        declaration at the top of the page.
+        * xterm.c (x_convert_modifiers): Declare this to return an
+        unsigned int, not a Lisp_Object.  Remember that the quiescent
+        value for part is Qnil, not zero, that x_mouse_x and x_mouse_y
+        are ints, not Lisp_Objects, and that RESULT->x and RESULT->y are

+        (XTread_socket): Declare this to return int, not Lisp_Object.
+        When calling construct_mouse_click on a non-scrollbar click, pass

+        x_screen_height_mm, x_screen_width, x_screen_width_mm,
+        x_save_under, x_screen_planes): Declare this as ints, to match
+        their definitions in xterm.c.
+        * ymakefile: Note the new dependencies caused by the new
+        #inclusions above.
+
+        * xdisp.c (last_arrow_position, last_arrow_string): Make these
+        static.
+
+        * process.c (pty_process): Variable deleted; it's no longer used.
+        (syms_of_process): Don't initialize it.
+
+        * buffer.h (struct buffer_local_types): This declaration needed an
+        extern qualifier.
+
+        * floatfns.c (Fexpt): Don't return the value of the XSET function
+        call; that's not guaranteed to be the value assigned.
+
+        * dired.c (Ffile_attributes): Doc fix.
+
+        * lisp.h (DEFVARLISP, DEFVARBOOL, DEFVARINT, DEFVARPERBUFFER):
+        Removed these definitions; we should be using the versions whose
+        names use underscores.
+
+        * keyboard.c (echobuf): Make this 300 characters, not 100.  This
+        isn't a real fix, but it's quick.
+
+1992-10-30  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+        * callint.c (preserved_fns): New var.

+1992-10-29  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+        * dispnew.c (count_blanks): Leave argument r constant, and increment p.
+
+1992-10-28  Jim Blandy  (jimb@totoro.cs.oberlin.edu)
+
+        * xdisp.c (message): Re-write this in terms of message1.
+        (message1): Move code to clear out echo_area_glyphs and
+        previous_echo_glyphs from message to here.
+
+        * keyboard.c (read_char): When returning an unread switch-frame
+        event, jump to reread_first to return it, rather than reread; this
+        makes sure the event gets echoed (if appropriate) and goes into
+        this_command_keys.
+
+        * keyboard.c (read_key_sequence): If the key sequence starts with
+        a mouse click, read the key sequence using the keymaps of the
+        buffer clicked on, not the current buffer.
+
+        * keyboard.c (unread_switch_frame): Make this static, to indicate
+        that nobody outside of this file uses it.
+
+        * keymap.c: Deal with autoloaded keymaps properly.
+        (get_keymap_1): Renamed to inner_get_keymap; made
+        static.  New argument AUTOLOAD says to pursue autoloads if
+        non-zero.
+        (Fkeymapp, get_keymap, get_keyelt, Flookup_key): Ask get_keymap_1
+        not to perform autoloads.
+        (Fdefine_key): Ask get_keymap_1 to perform autoloads.  Since
+        autoloading may GC, remember that we have to GCPRO our local
+        variables now.
+        (Fminor_mode_key_binding): Call get_keymap instead of calling

+        * emacs.c (main) [NeXT]: Call malloc_jumpstart.
+
+1992-10-05  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+        * window.c (window_loop): Pass 2nd arg to Fother_buffer.
+        * frame.c (make_frame): Likewise.
+        * callint.c (Fcall_interactively): Likewise.
+        * buffer.c (Fkill_buffer): Likewise.
+        (Fswitch_to_buffer, Fpop_to_buffer, Fbury_buffer): Likewise.
+
+1992-10-03  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)
+
+        * keyboard.c (read_key_sequence): Treat mouse clicks on non-text
+        areas as if they were prefixed with the symbol denoting the
+        area clicked on - `mode-line', etcetera.
+        When we throw away an unbound `down-' event, reset mock_input as
+        well.
+
+        * keyboard.c (Qevent_symbol_element_mask, Qmodifier_cache): Two
+        new symbols, used to implement caches on event heads.  These take
+        the place of some of the caching that modify_event_symbol used to do.
+        (parse_modifiers_uncached, apply_modifiers_uncached,
+        lispy_modifier_list, parse_modifiers, apply_modifiers): New
+        functions, which replace format_modifiers and reorder_modifiers;
+        they can be useful elsewhere too.
+        (reorder_modifiers, modify_event_symbol): Re-implement these in
+        terms of parse_modifiers and apply_modifiers.  modify_event_symbol
+        now uses a much simpler cache, and takes advantage of the caches
+        maintained by parse_ and apply_modifiers.
+        (follow_key): Don't modify NEXT if KEY has no bindings.
+        (read_key_sequence): Drop unbound `down-' events, and turn unbound
+        `drag-' events into clicks if that would make them bound.  This
+        benefits from the rewriting of the modifier key handling code.
+        (syms_of_keyboard): Initialize and intern
+        Qevent_symbol_element_mask and Qmodifier_cache.
+
+        * keyboard.c (echo_prompt): Terminate the echo buffer properly
+        even when the string is too long to display in the minibuffer.
+        (echo_truncate): Just return echoptr - echobuf, rather than
+        calling strlen on echobuf.
+
+        * alloc.c (Fmemory_limit): New function.
+        (syms_of_alloc): Defsubr it.
+
+        * window.c (SAVE_WINDOW_DATA_SIZE): Define this using sizeof,
+        instead of just saying it's 7; that way, we won't get screwed if 
+        we add members to struct save_window_data.
+
+        * window.c (struct save_window_data): Save the currently selected
+        frame, too.
+        (Fset_window_configuration): Restore the frame's selected window
+        using Fselect_window, and then restore the selected frame using
+        Fselect_frame.
+        (Fcurrent_window_configuration): Record the currently selected
+        frame.  Update docstring to describe the information now recorded.
+
+1992-10-02  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)
+
+        * process.c (wait_reading_process_input): Ultrix select seems to
+        return ENOMEM when interrupted.  So, under Ultrix, treat ENOMEM
+        like EINTR.
+
+        * keyboard.c (modifier_names): The modifier is named "control",
+        not "ctrl".
+
+        * keyboard.c (modify_event_symbol): Make sure that the unmodified
+        event header gets the proper properties set on it, by recursing
+        and letting the same code build the properties for all event symbols.
+
+        * keyboard.c (Qmouse_click): Fix typo which assigned `mouse-click'
+        symbol to Qmouse_movement.
+
+1992-10-02  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+        * undo.c (Fprimitive_undo):
+        When undoing an insert, move point and then delete.
+
+1992-10-02  Joseph Arceneaux  (jla@churchy.gnu.ai.mit.edu)
+
+        * intervals.c: `copy_intervals' no longer static.
+
+        * intervals.h: Declare `copy_intervals'.
+
+        * buffer.c: #include intervals.h.
+
+        * ymakefile: New macro "INTERVALS", controlled by "USE_INTERVALS",
+        which defines the interval include file "intervals.h".
+        New entries for "intervals.c" and "textprop.c".
+
+        * lisp.h: Declare Qbuffer_or_string_p.
+
+1992-10-02  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)
+
+        * xterm.c (x_find_modifier_meanings): If there are no
+        modifiers containing a Meta_ keysym, use the Alt keysyms to
+        denote meta.
+        (construct_mouse_click): Set the down_modifier bit on mouse
+        button press events.
+        (XTread_socket): When processing keypress events, use
+        x_meta_mod_mask when processing ordinary ASCII characters, not
+        just when processing function keys and other non-ASCII events.
+        (XTread_socket): If we receive a MappingNotify event with the
+        `request' member set to `MappingModifier', then call
+        x_find_modifier_meanings to refresh x_meta_mod_mask.
+
+        * window.c (Fset_window_configuration): Clean up the way we save
+        and restore the frame's size.
+
+        * termhooks.h (struct input_event): Doc fix.
+        (NUM_MOUSE_BUTTONS): New constant.
+        (click_modifier): New modifier.
+        (NUM_MODIFIER_COMBOS): Removed.
+
+        * keyboard.h (EVENT_HAS_PARAMETERS): Definition changed - all events
+        are not 5 elements long.
+        (EVENT_HEAD): Work correctly on all sorts of events, not just
+        events with parameters.
+        (EVENT_WINDOW, EVENT_BUFFER_POSN, EVENT_SCROLLBAR_BUTTON,
+        EVENT_WINDOW_POSN, EVENT_TIMESTAMP): These aren't useful
+        anymore; this information may appear twice in an event.  These
+        are replaced by the POSN_ accessors, which are meant to be
+        composed with the EVENT_START and EVENT_END accessors.
+        (EVENT_START, EVENT_END): Two new accessors, to get at the
+        starting and ending position of an event.
+        (POSN_WINDOW, POSN_BUFFER_POSN, PONS_SCROLLBAR_BUTTON,
+        POSN_WINDOW_POSN, POSN_TIMESTAMP): New macros, to futher
+        diasassemble the values returned by EVENT_START and EVENT_END.
+        * keyboard.c (echo_char, read_char): Apply EVENT_HEAD without first 
+        testing for EVENT_HAS_PARAMETERS; EVENT_HEAD works properly on
+        all sorts of events now.
+        (read_key_sequence): Use the new accessors to decide in which window
+        an event occurred.
+        * keymap.c (access_keymap, store_in_keymap,
+        Fsingle_key_description): No need to check for
+        EVENT_HAS_PARAMETERS before using EVENT_HEAD; the latter now
+        works properly on all sorts of events.
+
+        * keyboard.c (Qevent_unmodified): Replaced by...
+        (Qevent_symbol_elements): New property.
+        (syms_of_keyboard): initialize and staticpro the latter, not the
+        former.
+        * keyboard.h (Qevent_unmodified): Extern declaration replaced by...
+        (Qevent_symbol_elements): This.
+        (EVENT_HEAD_UNMODIFIED): Use the Qevent_symbol_elements
+        property, rather than the Qevent_unmodified property.
+
+        * keyboard.c (readable_events): This doesn't need to scan and
+        discard mouse release events anymore; it just uses
+        EVENT_QUEUES_EMPTY.
+        (kbd_buffer_get_event): No need to skip past mouse release events.
+
+        * keyboard.c (button_down_location): New variable, which
+        stores the location at which each button was pressed, so we
+        can build a complete drag event when the button is released.
+        (make_lispy_event): When a button is pressed, record its
+        location in button_down_location, and turn it into a `down'
+        event.  When a button is released, compare its release
+        location with its press location, and decide whether to call
+        it a `click' or `drag' event.
+        Change mouse movement events to be arranged like click events.
+        (format_modifiers): Note that the click modifier has no
+        written representation.
+        (modifier_names, modifer_symbols): New variables, used to
+        create the Qevent_symbol_elements property.
+        (modify_event_symbol): Change the format of the modified
+        symbol cache; there are too many modifier bits now to use a
+        vector indexed by a modifier mask.  Use an assoc-list instead.
+        Document the format of the cache.
+        Put the Qevent_symbol_elements property on each new symbol,
+        instead of a Qevent_unmodified property.
+        (symbols_of_keyboard): Put Qevent_symbol_elements properties on
+        the symbols specified in head_table, not Qevent_unmodifed properties.
+        Initialize and staticpro modifier_symbols, and staticpro the
+        window elements of button_down_location.
+
+        * xmenu.c: #include "keyboard.h".
+        (Fx_popup_menu): Use the event accessors defined in keyboard.h,
+        instead of writing out cars and cdrs.
+        * ymakefile: Note that xmenu.o depends on keyboard.h.
+
+1992-10-02  Joseph Arceneaux  (jla@wookumz.gnu.ai.mit.edu)
+
+        * textprop.c: Conditionalize all functions on
+        "USE_TEXT_PROPERTIES".
+        * intervals.c: Conditionalize all functions on
+        "USE_TEXT_PROPERTIES".
+        Removed #include of "screen.h".
+
+        * alloc.c: #include "intervals.h".
+        (init_intervals, make_interval,
+        mark_interval, mark_interval_tree): New functions conditionally
+        defined.
+        (make_uninit_string): Call INITIALIZE_INTERVAL.
+        (INIT_INTERVALS, UNMARK_BALANCE_INTERVALS, MARK_INTERVAL_TREE):
+        New macros, conditionally defined.
+        (mark_object): Call MARK_INTERVAL_TREE in case Lisp_String.
+        (gc_sweep): If text properties are in use, place all unmarked
+        intervals on the free list.  Call UNMARK_BALANCE_INTERVALS on
+        `buffer->intervals' when unmarking `buffer'.
+        (compact_strings): Include INTERVAL_PTR_SIZE in calculation for
+        target of bcopy when relocating strings.
+        (init_alloc_once): Call INIT_INTERVALS.
+        (make_pure_string): Include INTERVAL_PTR_SIZE in calculation of
+        `size'.
+        Moved static declaration of `mark_object' and other functions up
+        in the file.
+
+        * fileio.c (Finsert_file_contents): Call offset_intervals if
+        text was actually inserted.
+        #include "intervals.h".
+
+1992-09-30  Joseph Arceneaux  (jla@churchy.gnu.ai.mit.edu)
+
+        * data.c: Qbuffer_or_string_p added.
+
+        * syntax.c (describe_syntax): Use insert_char to insert `match'.
+
+        * buffer.c (reset_buffer): Do INITIALIZE_INTERVAL on the buffer's
+        interval component.
+        (Fkill_buffer): Likewise.
+
+        * editfns.c (make_buffer_string): Call copy_intervals_to_string.
+        (Finsert_buffer_substring): Call graft_intervals_into_buffer.
+        #include "intervals.h".
+
+        * insdel.c: #include "intervals.h"
+        (prepare_to_modify_buffer): Call verify_interval_modification.
+        (insert_from_string): Call offset_intervals and
+        graft_intervals_into_buffer.
+        (del_range): Call offset_intervals.
+        (insert): Call offset_intervals.
+
+        * emacs.c: #include "intervals.h".
+        (main): Call syms_of_textprop.  This is only really present if
+        Emacs is compiled with USE_TEXT_PROPERTIES defined.
+
+        * buffer.h: New macro TEMP_SET_PT.  If intervals are used, SET_PT
+        and TEMP_SET_PT are function calls.
+        Similarly for BUF_SET_PT and BUF_TEMP_SET_PT.
+        Added DECLARE_INTERVALS to buffer structure to conditionally
+        compile an interval tree into it.
+
+        * intervals.h: Declare temp_set_point.
+
+1992-09-30  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)
+
+        * ymakefile (config.h): Doc fix.
+
+1992-09-30  Joseph Arceneaux  (jla@churchy.gnu.ai.mit.edu)
+
+        * config.h.in: Added a slot for definition of USE_TEXT_PROPERTIES,
+        controlling compilation of interval code.
+        If using GNUC, support inline functions.
+
+        * lisp.h: Conditionally define interval structure and macros.
+        Add DECLARE_INTERVALS to struct Lisp_String.
+
+1992-09-30  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)
+
+        * buffer.c (Fother_buffer): Add back the VISIBLE_OK argument.  It
+        got removed with no comment or ChangeLog entry, and
+        append-to-buffer uses it.
+
+        * window.c (struct save_window_data): Add a member called
+        focus_frame, to save and restore the screen's focus frame.
+        (Fset_window_configuration): Redirect the frame's focus as
+        indicated in the window configuration.
+        (Fcurrent_window_configuration): Record the frame's current focus.
+        * minibuf.c (read_minibuf): Don't bother to save the current
+        frame's focus, and have read_minibuf_unwind restore it; saving and
+        restoring the window configurations will take care of that.
+        (read_minibuf_unwind): Don't worry about restoring the frame's focus.
+
+        * window.c (Fset_window_configuration): Don't select the frame
+        just because we restored its configuration.
+
+        * window.c (Fset_window_configuration): Don't forget to set the
+        frame's selected window when we can't call Fselect_window.
+
+        * xterm.c (x_meta_mod_mask): New variable, indicating which X
+        modifier bits denote meta keys.
+        (x_find_modifier_meanings): New function, to set x_meta_mod_mask.
+        (x_convert_modifiers): Use that.
+        (x_term_init): Call x_find_modifier_meanings.
+
+        * data.c (Fmake_local_variable): If SYM forwards to a C variable,
+        swap in the value for the current buffer immediately.
+
+        * lisp.h: Doc elaboration for Lisp_Buffer_Local_Value.
+
+1992-09-29  Joseph Arceneaux  (jla@churchy.gnu.ai.mit.edu)

+
+1992-09-29  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)
+
+        * xselect.c (Qcut_buffer0): Symbol removed; we're using a new
+        interface to the cut buffer now.
+        (NUM_CUT_BUFFERS, cut_buffer_atom, cut_buffer_value,
+        cut_buffer_cached, cut_buffer_just_set): New variables.
+        (Fx_own_selection, Fx_selection_value): Dike out the code to
+        handle CUT_BUFFER0 requests.
+        (Fx_get_cut_buffer, Fx_set_cut_buffer, x_watch_cut_buffer_cache,
+        x_invalidate_cut_buffer_cache): New functions.
+        (syms_of_xselect): Don't bother to initialize Qcut_buffer0.
+        Initialize and staticpro cut_buffer_value, and defsubr
+        Sx_get_cut_buffer and Sx_set_cut_buffer.
+        * xterm.c (XTread_socket): Pass PropertyNotify events from the
+        root window to x_invalidate_cut_buffer_cache.
+        (x_term_init): Call x_watch_cut_buffer_cache here.
+
+        * keymap.c (access_keymap): Don't forget to QUIT while scanning
+        the keymap.
+
+        * keyboard.c (recent_keys): This needs to be staticpro'ed.  Change
+        it from a C array, which is a pain in the neck to staticpro, into
+        a lisp vector, which is easier.
+        (read_char, Frecent_keys): Access recent_keys as a lisp vector,
+        not a C array.
+        (syms_of_keyboard): Set recent_keys to be a vector, and staticpro it.
+
+        * ymakefile (xfns.o): This doesn't depend on xselect.c.
+
+        * xterm.h (ROOT_WINDOW): Use the DefaultScreen macro, not the
+        XDefaultScreen function.
+
+        * frame.c (Fdelete_frame): Call Fselect_frame with the appropriate
+        number of arguments.
+
+        * data.c (Frem): Use the `fmod' function under SunOS, Ultrix, and
+        HP/UX, not just under USG systems.
+
+        * buffer.c (Fbury_buffer): This used to undisplay the buffer being
+        buried only if the BUFFER argument was nil.  Instead, undisplay the
+        buffer whenever it's displayed in the selected window, no matter
+        how it was specified by BUFFER.  This is how it behaves in 18.58,
+        and I can't find any ChangeLog entry in 18.58 or 19.0 saying why
+        they differ.  Fix the doc string accordingly.
+
+1992-09-28  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)
+
+        * frame.c (Fselect_frame, Fframe_root_window,
+        Fframe_selected_window, Fnext_frame, Fmake_frame_visible,
+        Fmake_frame_invisible, Ficonify_frame): Doc fixes.
+
+        * ralloc.c: Since the users of the relocating allocation code
+        handle memory exhaustion, it's better to return an error code to
+        them than to call abort. 
+        (obtain): If we cannot allocate more memory, don't call
+        abort.  Instead, return non-zero iff the allocation is successful.
+        (get_more_space): If obtain fails, return zero.
+        (get_bloc): Return zero if we can't allocate the new bloc.
+        (r_alloc_sbrk): Return zero if we can't allocate more memory.
+        (r_alloc): If we can't allocate more memory, set *PTR to zero and
+        return zero.
+        (r_re_alloc): If we can't allocate more memory, leave *PTR
+        unchanged, and return zero.
+
+        * ralloc.c (warnfunction): Renamed to warn_function; users changed.
+
+1992-09-28  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+        * insdel.c (del_range): Call record_delete before updating point.
+
+        * fileio.c (Finsert_file_contents): Do record_insert, then inc MODIFF.
+
+        * undo.c (record_delete): Record pos before the deletion.
+        (Fprimitive_undo): Go back to recorded position.
+
+1992-09-28  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)
+
+        * window.c (delete_all_subwindows): Save the window's buffer in
+        its `height' field; we may need to know the window's old buffer
+        once we have restored it from a window configuration.
+        (Fset_window_configuration): When we restore a window, if its
+        `height' field is a buffer, restore its `buffer' field from that.
+        This allows us to leave the window's buffer unchanged if the
+        buffer recorded in the configuration is dead.
+
+        * window.c (delete_all_subwindows): Removed unused variable named
+        "count".
+
+1992-09-27  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)
+
+        * keyboard.c (read_char): If we're returning an event from a
+        macro, set Vlast_event_frame to Qmacro, instead of leaving it set
+        to the frame of the previous real event.
+        (read_key_sequence): If Vlast_event_frame isn't a frame, don't
+        bother switching buffers.
+        (syms_of_keyboard): Doc fix for Vlast_event_frame.
+        (Vlast_event_frame): Doc fix.
+
+        * termhooks.h (alt_modifier, hyper_modifier, super_modifier,
+        down_modifier, drag_modifier): New modifiers, to support the new
+        input system.  Re-arranged modifiers so that their bits are in
+        canonical order; this makes reorder_modifiers slightly simpler.
+        * keyboard.c (format_modifiers, reorder_modifiers): Handle the new
+        modifier bits.
+
+        * keymap.c (access_keymap): Remove code to notice bindings for
+        Qt.
+
+1992-09-25  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

+
+1992-09-25  Jim Blandy  (jimb@geech.gnu.ai.mit.edu)
+
+        * keymap.c (Fwhere_is_internal): Don't forget to advance map to
+        the next element when we find something that is neither a vector
+        nor a cons.  Don't forget to QUIT in the appropriate places,
+        either.
+
+1992-09-23  Joseph Arceneaux  (jla@geech.gnu.ai.mit.edu)
+
+        * textprop.c (Fset_text_properties): Merge adjacent intervals with
+        the same properties.
+        (Fnext_single_property_change, Fprevious_single_property_change):
+        New subrs.
+
+        * intervals.c (merge_interval_left, merge_interval_right): Abort
+        if caller tries to merge first (or last, respectively) interval.
+        Delete the interval node after merging.
+        (copy_intervals): Use `split_interval_right' rather than creating
+        new intervals with make_new_interval and attaching them
+        explicitly.
+        (verify_interval_modification): Changed error message.  GCPRO
+        hooks before calling Fnreverse, and correctly Fcdr down the list.
+        Also, don't cons multiple copies of the same consecutive
+        modification hook.
+        (temp_set_point): New function.
+        (set_point): Call point-left and point-entered hooks if moving
+        between text with different properties.  Use the old and new
+        positions as arguments to these calls.
+
+        * intervals.c, intervals.h: (map_intervals, make_buffer_interval,
+         make_string_interval,run_hooks): Deleted.
+
+1992-09-23  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)
+
+        * keymap.c (DENSE_TABLE_SIZE): Doc fix.
+        (keymap_table): Function removed; this function exists only to
+        support an incorrect understanding of the format of keymaps.
+        (access_keymap, store_in_keymap, Fcopy_keymap,
+        Faccessible_keymaps): Correctly handle vectors at any point in the
+        keymap; don't assume it must be at the front.
+        (describe_map): Instead of calling describe_vector on the vector
+        in the cadr of the keymap (if present) and then calling
+        describe_alist to do the rest, just call describe_map_2.
+        (describe_alist): Renamed to describe_map_2; call describe_vector
+        when we encounter a vector in the list.
+        * xmenu.c (single_keymap_panes): Comment out the code which
+        tries to handle a dense keymap's table; it uses keymap_table, and
+        the rest of the code never uses the table contents anyway.
+
+        * keymap.c (access_keymap, store_in_keymap): Clarify error message
+        for non-ASCII characters.
+
+        * process.c [SIGCHLD && !BSD && !UNIPLUS && !HPUX]
+        (create_process): #if 0 out the code which sets the child's
+        handler for SIGCHLD to sigchld; the code which gives sigchld its
+        value has been diked out under these CPP symbols, so this should
+        be diked out too.
+
+        * indent.c (Fmove_to_column): Pass the right number of arguments
+        to Findent_to.
+
+1992-09-22  Jim Blandy  (jimb@kropotkin.gnu.ai.mit.edu)
+
+        * emacs.c (emacs_priority): Doc fix.
+        (main): Use nice, not setpriority; we just need a
+        simple, portable call to nice here.
+        * callproc.c (child_setup): Use nice, not setpriority.
+        * sysdep.c (sys_suspend): Don't try to use "nice (- nice (0))" to
+        set the subshell's priority to normal; nice doesn't return a
+        defined value on all systems.  Instead, since emacs_priority gives
+        the priority that Emacs was nastied to, we can use it to reset the
+        priority in a straightforward way.
+        [BSD4_1], [USG], [VMS] (setpriority): Remove dummy and
+        compatibility definitions of setpriority.
+
+        * keymap.c (access_keymap): Return the binding of Qt as the
+        binding for all unbound characters.
+
+        * fileio.c (syms_of_fileio): Don't try to defsubr Sunix_sync
+        unless it's actually been defined - that is, if unix is #defined.
+
+        * xrdb.c (x_get_resource): Cast the value being assigned to
+        ret_value->addr, rather than ret_value->addr itself; only GCC
+        allows you to cast lvalues.
+
+        * eval.c (unbind_catch): Do the long-jump here.  Take a VALUE
+        argument, which specifies the value to return to the catch, or the
+        data to give to the condition handler.  Renamed to
+        unwind_to_catch, to reflect new role.
+        (Fsignal, Fthrow): Removed code to set catch tag value and do the
+        long-jump; this is taken care of by unwind_to_catch.
+
+1992-09-21  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+        * alloc.c (mark_object): Avoid car recursion on cons with nil in cdr.
+        Avoid recursion on constants-vector of a compiled function.
+
+        * oldXMenu: Symlink deleted; anything that uses it needs fixing
+        in any case to work properly on systems without symlinks.
+
+1992-09-20  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+        * s/sol2.h: New file.
+
+        * fileio.c: Don't include sys/dir.h.
+
+        * s/usg5-4.h (LIBS_SYSTEM): Move non-default libraries here.
+        (LIB_STANDARD, START_FILES): Deleted.
+        (ORDINARY_LINK): Defined.
+
+        * ymakefile [ORDINARY_LINK]: Default LD to $(CC)
+        and make START_FILES and LIB_STANDARD empty.
+        (C_SWITCH_X_MACHINE, C_SWITCH_X_SYSTEM): New macros, default empty.
+        (CFLAGS): Use them.
+
+1992-09-19  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+        * ymakefile (${etc}DOC): Use OBJECTS_SYSTEM and OBJECTS_MACHINE.
+
+        * dired.c [VMS]: Include string.h, rms.h, rmsdef.h.
+        [VMS] (Ffile_version_limit): New function.
+
+        * sysdep.c (sys_suspend): Read EMACS_PARENT_PID envvar for parent. 
+
+        * syntax.c (scan_lists): When searching back for comment:
+        if comment-end is 2 chars, assume it does end a comment.
+        Otherwise, scan back to previous comment-end to see if there's
+        a comment starter between.  Also record whether the string quotes
+        between the start and the end are paired and uniform.
+        If so, skip to comment starter.  If not, scan from start of
+        defun to find comment starter if any.
+        (find_defun_start): New function.
+
+        * alloc.c (mark_object): Save last 500 values of objptr.
+        Check for clobberage of ptr, when marking a vector.
+
+1992-09-18  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+        * keymap.c (get_keyelt): Skip menu help string after menu item name.
+
+1992-09-18  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+        * buffer.c (Fget_buffer_create): Doc fix.
+
+        * lisp.h (struct handler): Remove the poll_suppress_count member
+        of this structure; it is always equal to the poll_suppress_count
+        of its catchtag structure.  The non-local exit code in eval.c is
+        difficult enough to understand as it is; needless duplication
+        doesn't help.
+        * eval.c (Fcondition_case): Rearranged for clarity.  Don't worry
+        about setting h.poll_suppress_count; it's guaranteed to be the
+        same as c.poll_suppress_count.
+        (internal_condition_case): Don't worry about
+        h.poll_suppress_count.
+        (Fsignal): Use h->tag->poll_suppress_count instead of
+        h->poll_suppress_count.
+
+        * eval.c (Fsignal): It's okay for the debugger to return to the
+        caller if the caller was signalling a quit.
+
+        * eval.c (unbind_catch): Restore the polling suppression count
+        here, instead of in Fsignal and Fthrow.
+        (Fthrow, Fsignal): Don't restore the polling suppression count here.
+        
+        * lisp.h (struct specbinding, struct handler): More documentation.
+        * eval.c (struct catchtag): More documentation.
+
+1992-09-17  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+        * ymakefile (LIBX): Don't use -loldX.
+
+1992-09-17  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+        * minibuf.c (get_minibuffer): Enable undo in minibuffers.
+
+1992-09-14  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+        * ymakefile (LIBXMENU): Check NO_X_MENU, not HAVE_X_MENU
+        * emacs.c (main): Use X menu code if HAVE_X_WINDOWS and not NO_X_MENU.
+        * keyboard.c (read_char_menu_prompt): Likewise.
+
+        * config.h.in: Delete everything about config.h.
+
+        * emacs.c: Eliminate HIGHPRI as compilation option.
+        (emacs_priority): New C variable, also Lisp variable.
+        (main): Set the priority iff emacs_priority is nonzero.
+
+1992-09-14  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+        * eval.c (entering_debugger): Variable renamed
+        when_entered_debugger, and is now a timestamp based on
+        num_nonmacro_input_chars.
+        (init_eval): Initialize when_entered_debugger, not
+        entering_debugger.
+        (call_debugger): Set when_entered_debugger to the current value of
+        num_nonmacro_input_chars.
+        (find_handler_clause): Don't call debugger unless
+        num_nonmacro_input_chars is greater than when_entered_debugger;
+        that way, we won't call the debugger unless the user has had a
+        chance to take control.
+        (Fbacktrace): Don't clear entering_debugger here.
+        * keyboard.h (num_nonmacro_input_chars): Added extern declaration
+        for this.
+
+        * fns.c (Fy_or_n_p): After testing for a QUIT, clear Vquit_flag.
+        Otherwise, if Fy_or_n_p is called while Vinhibit_quit is true and
+        the user presses C-g, this function goes into an infinite loop.
+
+        * dispnew.c (get_display_line): Don't abort if the frame is
+        invisible; since unmap events are handled at the interrupt level,
+        a screen may become invisible at any time.
+
+1992-09-13  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+        * fileio.c (Fverify_visited_file_modtime):
+        Pass buffer itself to handler, if have handler.
+        (Fwrite_region): GCPRO around Fexpand_file_name, Ffile_name_directory.
+        (Fread_file_name_internal): GCPRO around file name manip.
+        (Ffile_writable_p, Ffile_readable_p): Use abspath, not filename,
+        (Ffile_executable_p, Ffile_exists_p): to run the handler.
+        (Fset_file_modes, Ffile_directory_p, Ffile_modes): Likewise.
+        (Ffile_newer_than_file_p): GCPRO around expand_and_dir_to_file.
+
+1992-09-13  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+        * s/bsd4-3.h: Give the BSD4_3 and BSD symbols the same numeric
+        definitions they'll get in <sys/param.h>, to avoid warnings.
+
+        * m/hp9000s300.h: Don't include <sys/wait.h>.  This really
+        shouldn't be necessary.
+        (BIG_ENDIAN): Define this as "4321", to agree with
+        <machines/endian.h>, and avoid warnings.
+
+        * systime.h: Re-arrange inclusion of <sys/time.h> and <time.h> so
+        that they don't both get included under BSD, and do both get
+        included under AIX.
+
+        * xdisp.c (display_mode_line): If the only other frames are
+        minibuffer frames, don't name the frame after the in the selected
+        window.  We can use Fnext_frame to do this test easily.
+
+1992-09-12  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+        * process.c (Faccept_process_output): Initialize useconds.
+
+        * keyboard.c (num_nonmacro_input_chars): New variable.
+        (read_char): Use num_nonmacro_input_chars to decide on auto-save & gc.
+        Increment it when appropriate.
+        (record_auto_save): Use num_nonmacro_input_chars.
+
+        * fileio.c (Ffile_name_directory, Ffile_name_nondirectory): 
+        (Ffile_name_as_directory, Fdirectory_file_name, Fexpand_file_name): 
+        Call find_file_handler.
+        (syms_of_fileio): Set up Qfile_name_directory, etc.
+        (Fcopy_file): Call find_file_handler for newname as well as for filename.
+        (syms_of_fileio): Initialize Vfile_name_handler_alist.
+
+1992-09-11  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+        * callint.c (Fcall_interactively): Remove the 'K' interactive
+        code, in favor of 'e'; that's a better name.
+
+1992-09-11  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+        * s/esix5r4.h: New file.
+
+        * sysdep.c (init_sys_modes): Handle VDSUSP like V_DSUSP.
+        Use CDISABLE, not CDEL.
+        Turn off IEXTEN if it exists.
+        * systty.h (CDISABLE): New macro; may be defined from CDEL.
+
+        * keyboard.c (command_loop_1): Bind inhibit-quit to t when in Fsit_for.
+
+1992-09-10  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+        * Makefile.in: Add comments starting with "# DIST: " explaining
+        that this gets munged by the configure script.
+
+1992-09-10  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+        * s-aix3-1.h (HAVE_GETHOSTNAME): Defined.
+
+1992-09-09  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+        * frame.c (choose_minibuf_frame): abort if the selected frame has
+        nil in its minibuffer_window slot; this shouldn't happen any more.
+        * window.c (minibuffer_window): Accept an optional FRAME argument;
+        if specified, return the minibuffer used by that frame.
+
+        * keymap.c (describe_buffer_bindings): Adjust key_heading to match
+        the format used by describe_map_tree.  Also, don't reprint the
+        "key    binding" header above the global bindings if we've already
+        printed it for the local bindings; it's clear enough that the
+        columns mean the same thing as above.
+
+1992-09-08  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+        * ralloc.c (r_re_alloc): Instead of allocating a new bloc at the
+        end of the heap, copying the data to it, and then freeing the
+        original bloc, just expand the original block.  This saves a copy
+        and a call to sbrk, and also removes the large spike in memory
+        allocation that would occur when resizing large buffers.  And it's
+        less code.
+
+        * keyboard.h (Vkeyboard_translate_table): Declare this extern
+        here, so describe_buffer_bindings can use it.
+        * keymap.c (describe_buffer_bindings): Declare buf and bufend...
+
+1992-09-05  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+        * systime.h: Always #include <time.h>, not just when NEED_TIME_H
+        is defined.  It gets us struct tm.  #include <sys/time.h> whenever
+        HAVE_TIMEVAL is defined and NEED_TIME_H isn't.
+
+        * systime.h: Note that the tz_dsttime field of the struct timezone
+        returned by gettimeofday doesn't say whether daylight savings is
+        _currently- active; rather it specifies whether it is *ever*
+        active.
+        (EMACS_GET_TZ_OFFSET_AND_SAVINGS): Removed `savings_flag'
+        argument, and renamed to EMACS_GET_TZ_OFFSET.  Don't try to
+        extract savings information.  EMACS_CURRENT_TIME_ZONE should call
+        localtime to figure out whether DST is active.
+
+        * m/hp9000s300.h: #include <sys/wait.h> before doing anything
+        else, to avoid conflicts between the system's and Emacs's
+        definitions of BIG_ENDIAN.
+
+        * keymap.c (describe_buffer_bindings): Set the current buffer to
+        descbuf before calling current_minor_maps; that function's value
+        depends on the values of buffer-local variables.  Don't set the
+        current buffer to Vstandard_output until afterwards.
+
+        * keymap.c (describe_buffer_bindings): If
+        Vkeyboard_translate_table is in effect, describe its effects.
+
+        * frame.c (Fnext_frame): Doc fix.
+
+        * frame.c (prev_frame): #if 0'd out; nobody uses this.
+
+        * frame.c (next_frame): The logic which determines whether a frame
+        is acceptable to return was misarranged; rewrote it.
+        (prev_frame): Same thing.
+
+1992-09-05  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+        * syntax.c (scan_lists): Improve smarts for backwards scan of comments.
+        Don't modify comstyle inside that loop.
+        If string quotes don't match up, don't take value from OFROM;
+        instead, parse forward using scan_sexps_forward.
+        (scan_sexps_forward): Return value via a pointer passed in.
+        New element in state contains char addr of last comment-starter seen.
+        (Fparse_partial_sexp): Change call to scan_sexps_forward.
+
+1992-09-04  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+        * xmenu.c (xmenu_show): If no panes, just return.
+
+        * keyboard.c (last_nonmenu_event): New var.
+        (syms_of_keyboard): New Lisp var.
+        (read_key_sequence): Use that instead of prev_event.
+        * commands.h (last_nonmenu_event): Declared.
+        * callint.c (Fcall_interactively): For `K', use last_nonmenu_event.
+        Make `e' alias for `K'.
+
+1992-09-03  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+        * editfns.c (Fcurrent_time_string): Change docstring to
+        indicate that we will probably add the timezone to the end,
+        now that we have it available on many systems.
+
+        * xrdb.c: Don't include <X11/Xos.h>.  Under R4, it stupidly
+        insists on defining SIGCHLD, even if it already has a definition.
+        (file_p): Use the constant 4 instead of R_OK; empirically, the
+        number is more portable than the symbol if you count the #include
+        hair you have to go through to get R_OK defined.  Ffile_readable_p
+        does this too.
+
+        * xterm.c (x_wm_set_size_hint): Set the base_width and base_height
+        members of size_hints, if they're available (X11R4 and after);
+        otherwise, approximate the right thing, by using min_width and
+        min_height as the base size.
+
+1992-09-02  Barry A. Warsaw   (warsaw@anthem.nlm.nih.gov)
+
+        * Extended syntax.c in the following ways to support up to 2
+        orthogonal comment styles per mode.  This is needed for C++.
+        Bit 6 of syntax table entry for a character indicates
+        it is part of the `b' comment style.  Otherwise it is
+        part of the `a' style.
+        * syntax.h (SYNTAX_COMMENT_STYLE): New macro.
+        * syntax.c (Fmodify_syntax_entry): Set that flag for `b'.
+        (describe_syntax): Print the `b' flag.
+        (scan_lists, scan_sexps_forward): Handle the new flag.
+        (Fparse_partial_sexp): Return new element in value.
+
+1992-09-02  Roland McGrath  (roland@geech.gnu.ai.mit.edu)
+
+        * fileio.c (syms_of_fileio): Doc fix for Vfile_name_handler_alist.
+
+1992-09-02  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+        * keyboard.c (kbd_buffer_get_event): When performing the
+        FRAME_FOCUS_FRAME redirection, don't modify the frame field of
+        the event; that fatally corrupts mouse click events.  Instead,
+        just perform the redirection on the value assigned to
+        Vlast_event_frame.
+
+        * callint.c (Fcall_interactively): Don't try to get the
+        `enable-recursive-minibuffers' property from FUNCTION unless
+        FUNCTION is actually a symbol; there are some cases where a key
+        sequence is bound directly to a lambda form, and there's no reason
+        to break these.
+
+        * window.c (Fset_window_configuration): Don't signal an error
+        if the frame size saved in the window configuration doesn't
+        match the frame's current size; instead, temporarily resize
+        the frame while installing the window configuration.  This is
+        important because using the minibuffer saves and restores the
+        current window configuration, and you don't want to signal an
+        error just because the user resized the frame while using the
+        minibuffer.
+
+        * doc.c (Fsnarf_documentation): Signal an error if this is
+        called in a dumped Emacs.
+
+        * alloc.c (mark_object): mark a symbol's name after marking its
+        value, function, and property list rather than before; this way,
+        symbols' names are readable, giving us a chance to detect some
+        kinds of heap corruption.
+
+1992-09-02  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+        * emacs.c (__main, __do_global_dtors): New dummy functions.
+        (__do_global_ctors_aux, __do_global_ctors): Fix typo in fn names.
+
+1992-09-01  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+        * prefix-args.c: New file.  See comment at top of file.
+        * ymakefile (YMF_PASS_LDFLAGS): Use the prefix-args program to
+        affix the -Xlinker prefix to the linker arguments.
+        (prefix-args): New target.
+        (temacs): Depend on prefix-args.
+
+        * xterm.c (x_catch_errors): Don't forget to initialize
+        x_caught_error_message to the null string, so x_check_errors can
+        tell when an error has occurred.
+
+        * unexmips.c (mark_x): Declare this as static void at the top of
+        the file and at the function definition.
+
+        * keyboard.c (input_available_signal): Declare this to return
+        SIGTYPE.
+
+        * xrdb.c (getuid): Declare this to return short.
+
+        * s/bsd4-3.h: Remove definition of SIGTYPE macro; Mt. Xinu says
+        it's int, but Ultrix says it's void.  Since the SIGTYPE guessing
+        code in the `configure' script gives the correct answer for both
+        of these cases, there's no point in listing it here.
+
+        * systime.h (EMACS_CURRENT_TIMEZONE): Change documentation to
+        indicate that *OFFSET should be set to the number of minutes EAST
+        of Greenwich, which is what Ed Reingold says real time gurus want.
+        Changed the definition of the EMACS_GET_TZ_OFFSET_AND_SAVINGS
+        macro to reflect this.  Buggily, the Fcurrent_time_zone function
+        was already expecting minutes east of GMT.
+
+        * Makefile.in (distclean): Remove backups from the `m' and `s'
+        directories, too.
+
+        * m/mips.h: Merge changes from Emacs 18.58:
+        [NEWSOS5]: Changes so this file can be used with s/newsos5.h.
+        (SIGN_EXTEND_CHAR): Define this using a cast to signed char.  I
+        guess the MIPS compiler and its derivatives all have this type.
+        (HAVE_ALLOCA, C_ALLOCA): Define the former if we're compiling with
+        GCC, and the latter otherwise.
+        (C_SWITCH_MACHINE): Defined, instead of C_SWITCH_SYSTEM.
+        (LINKER): Defined, if BSD.
+        (XUINT, XSET, XUNMARK): Add parentheses to eliminate warnings from
+        GCC.  Reindent to fit in 80 columns.
+        INHIBIT_BSD_TIME prevents including bsd/sys/time.h.
+        * s/newsos5.h: New file for Sony NEWS-OS release 5, courtesy of
+        Chris Hanson <cph@klia.ai.mit.edu>.
+
+        * m/mips.h: Don't undefine LOAD_AVE_TYPE; the comment says that
+        Emacs 19 has the crocks to handle it properly.
+
+        * m/pmax.h: Merge changes from Emacs 18.58:
+        (LIB_STANDARD, COFF, TERMINFO): Cancel out definitions from
+        m/mips.h which are only appropriate for USG.
+        (MAIL_USE_FLOCK, HAVE_UNION_WAIT): Do define these.
+        (BROKEN_O_NONBLOCK): Defined.
+        (LINKER): Don't define this.
+        [OSF1]: Undef C_ALLOCA, define HAVE_ALLOCA.
+        
+        * s/osf1.h: New file.
+
+        * s/bsd4-3.h: Merge changes from Emacs 18.58:
+        (BSD, BSD4_3): Just define these, don't fret about numerical
+        values or version numbers.
+
+        * m/hp9000s300.h: Merge changes from Emacs 18.58, and hp300bsd.h:
+        Change configuration note to say it's okay to use this file for BSD.
+        Add comment saying that NOMULTIPLEJOBS must be defined for
+        versions of HP/UX before 6.5.
+        Don't define BIG_ENDIAN if it seems that <endian.h> has already
+        done so.
+        [BSD4_3] Define m68000, instead of hp9000s300; crt0.c uses these
+        to decide what sort of startup code to use.
+        [not BSD4_3] Under HP/UX, always define the BSD memory functions
+        (bcopy, bzero, and bcmp) in terms of the SYSV string functions
+        (memcpy, memset, and memcmp), not just under HP/UX 5; version 6's
+        BSD compatibility library has reported bugs in `signal'.
+        (NEED_BSDTTY): Move this symbol's definition inside the "not
+        BSD4_3" conditional, since it's only relevant to HP/UX.
+        * m/hp300bsd.h: File deleted, since m/hp9000s300.h now
+        works with both HP/UX and BSD; it includes m/hp300bsd.h's
+        specifications.
+
+        * m/hp9000s300.h: Remove definition for SIGN_EXTEND_CHAR; this is
+        only used by the regexp code, which has its own portable
+        definition these days.
+
+1992-08-31  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+        * keymap.c (Fmake_sparse_keymap): New optional arg.  Callers changed.
+        (Fmake_keymap): Likewise.
+
+        * emacs.c (__do_global_ctors, __do_global_ctors_aux): New dummy fns.
+        (__CTOR_LIST__, __DTOR_LIST__): New dummy variables.
+
+        * fileio.c (Fdo_auto_save): Always call record_auto_save.
+
+        * keyboard.c (read_char): Call read_char_menu_prompt here.
+        Accept 4 new args to pass to it.  Include them in recursive call.
+        Don't delay before starting echo if prev_event was a mouse event.
+        Test for eof in batch mode now understands C is a Lisp_Object.
+        (read_key_sequence): Don't call it here; always call read_char.
+        Don't change last_event_buffer after a mouse menu input.
+        (read_char_menu_prompt): Arg PROMPT deleted.
+        Return nil if nothing to do.
+
+        * xmenu.c (Fx_popup_menu): Treat coords relative to spec'd window.
+        (single_keymap_panes): New function; contains guts of keymap_panes.
+        If a command binding for submenu has a prompt string starting with @,
+        make a separate pane for it at this level.
+
+        * xfns.c (Fx_track_pointer): Pass new args to read_char.
+        (Fx_select_region, Fx_horizontal_line): Likewise.
+        * lread.c (Fread_char): Pass new args to read_char.
+        (Fread_event, Fread_char_exclusive): Likewise.
+        * fns.c (Fy_or_n_p): Pass new args to read_char.
+
+1992-08-30  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+        * keyboard.c (read_key_sequence): Keep track of prev_event.
+        Pass new proper args to read_char_menu_prompt.
+        (read_char_menu_prompt): New arg prev_event.  Use Fx_popup_menu.
+        Handle any number of keymaps, not just LOCAL and GLOBAL.
+        Invert meaning of arg PROMPT.  Test of menu_prompting was backwards.
+
+        * keymap.c (keymap_table): No longer static.
+
+        * xmenu.c (keymap_panes): New function.
+        (Fx_popup_menu): Accept keymap or list of keymaps as MENU argument.
+        Accept mouse button event as POSITION argument.
+
+1992-08-29  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+        * cmds.c (internal_self_insert): Assume Fexpand_abbrev expanded
+        something if it incremented MODIFF.
+
+1992-08-28  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+        * unexmips.c (unexec): Allow sections in any order.
+        Adjust addresses of rdata section as well as data section.
+
+        * buffer.c (syms_of_buffer): Made buffer-display-table,
+        buffer-field-list and buffer-undo-list allow any type of value.
+
+1992-08-27  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+        * fns.c (Fappend): Doc fix.
+
+1992-08-24  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+        * s/usg5-4.h: Incorporate changes from 18.58:
+        (LIBX10_SYSTEM): Undefine this.
+        (GNULIB): Definition deleted -- done in ymakefile.
+        (LIB_STANDARD): Don't use GNULIB.
+        (HAVE_TCATTR): Defined.
+
+        * xfns.c (x_icon): Don't call x_wm_set_icon_positions if the user
+        hasn't specified the icon position.  Let the window manager put
+        the icon where it likes.
+
+        * xterm.c (x_make_frame_invisible): Don't forget to check the
+        return value of XWithdrawWindow; it could indicate that the window
+        wasn't successfully redrawn.
+
+        * sysdep.c (init_baud_rate): Re-arranged order of conditionals -
+        test TERMIOS before TERMIO; when two options might both be
+        defined, test the most recent first, so that the most recent
+        functions get used.
+
+        * sysdep.c [HAVE_TERMIO] (init_baud_rate): Don't use tcgetattr
+        unless HAVE_TCATTR is defined.  Only very rarely do termio systems
+        have the tc{get,set}attr macros.
+
+        * window.c (coordinates_in_window): Do not assume that all
+        one-line windows are the minibuffer, or that all minibuffers are
+        one line high.  Use MINI_WINDOW_P.
+
+        * systerm.h: Renamed to systty.h, to be more consistent with
+        everything else in Unix.
+        * dispnew.c, emacs.c, keyboard.c, process.c, sysdep.c: #include
+        directive changed.
+        * ymakefile: References to systerm.h changed.
+
+        * s/usg5-3.h: Merged changes from 18.58:
+        (HAVE_SYSV_SIGPAUSE): Defined.
+        (BROKEN_TIOCGETC): Defined.
+
+1992-08-21  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+        * process.c (WCOREDUMP): Define only if not defined.
+        (create_process) [HAVE_SETSID]: Use TIOCSCTTY if exists.
+        
+1992-08-20  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+        * fileio.c (Fdo_auto_save): Call Fsleep_for with the appropriate
+        number of arguments.
+        * fns.c (Fyes_or_no_p): Same.
+
+        * dispnew.c (update_frame): Change the way we handle
+        cursor_in_echo_area.  Firstly, ignore this if the frame we're
+        updating doesn't have a minibuffer.  Secondly, don't handle the
+        selected frame specially.  Thirdly, don't assume that the
+        minibuffer is only one line high.  If cursor_in_echo_area < 0, put
+        the cursor in the upper-left corner; if cursor_in_echo_area > 0,
+        put it on the lowest non-empty line in the minibuffer window, or
+        on the top line.
+
+        * dispnew.c (direct_output_for_insert): Fail if
+        cursor_in_echo_area is set; we don't want to do the typing there.
+        (direct_output_for_insert): Same.
+
+1992-08-19  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+        * xterm.c (x_make_frame_invisible): Use XWithdrawWindow when
+        available [HAVE_X11R4]; send the UnmapNotify event when
+        appropriate [HAVE_X11]; just unmap the window if that's all that's
+        needed [not HAVE_X11].
+
+        * xterm.c (x_set_text_property): Removed; it's only called from
+        one place.  Who wants *another* layer of indirection?
+        * xfns.c (x_set_name): Use XSetWM{Name,IconName} when available
+        [HAVE_X11R4], or XSetIconName and XStoreName otherwise.
+
+        * xterm.h (FRAME_X_WINDOW): New macro, for readability.
+        * xterm.c, xfns.c, xselect.c: Use it.
+
+        * emacs.c (Fkill_emacs): Doc fix.
+        (syms_of_emacs): Doc fix for Vkill_emacs_hook.
+
+        * xterm.c (x_death_handler): Renamed to x_connection_closed.
+        (x_term_init): Use x_connection_closed as the SIGPIPE handler.
+
+        * xterm.c (acceptable_x_error_p, x_handler_error_gracefully,
+        x_error_handler): Removed; you can't catch X errors this way,
+        since you can't perform X operations from within an X error
+        handler, and even though we call error, we're still within an X
+        error handler.
+        (x_error_quitter, x_error_catcher): New functions, for panicking
+        on and catching X protocol errors.
+        (x_caught_error_message): Buffer for caught X errors.
+        (x_catch_errors, x_check_errors, x_uncatch_errors): New functions
+        for catching errors.
+        (x_term_init): Set the error handler to x_error_quitter, rather
+        than x_error_handler.
+        * xfns.c (x_set_mouse_color): Use x_catch_errors, x_check_errors,
+        and x_uncatch errors to avoid crashing if the user selects an
+        odd cursor.
+
+        * xterm.c (x_proto_requests): Removed; it's not important.
+        
+        * xterm.c (events): Array removed; it's not used.
+
+        * xfns.c (select_visual): Use XVisualIDFromVisual when available
+        [HAVE_X11R4].
+        
+        * xrdb.c (get_user_db): Use XResourceManagerString when available
+        [HAVE_X11R4].
+
+        * window.c (change_window_height): If the size of the window will
+        shrink below the minimum, this code would only try to delete it if
+        it had a parent.  Well, even if the window doesn't have a parent,
+        you want Fdelete_window to signal an error, since you're trying to
+        resize one of the undeleteable windows into nothingness.  So call
+        Fdelete_window even if the window doesn't have a parent.
+
+        * window.c (MINSIZE): Add kludge so that the minibuffer is always
+        allowed to shrink to one line in height.
+        (MINSIZE, CURBEG, CURSIZE): Change these so that their argument
+        are always Lisp_Objects, not struct window *'s.
+        (change_window_height): Changed accordingly.
+
+1992-08-18  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+        * frame.h (struct frame): New member - explicit_name.
+        * frame.c (make_frame): Clear it.
+        * xfns.c (x_set_name): Take new argument EXPLICIT, instead of
+        OLDVAL.
+        (x_explicitly_set_name, x_implicitly_set_name): New functions.
+        (x_frame_parms): Use x_explicitly_set_name here.
+        (x_window): Use x_implicitly_set_name here.
+        * xdisp.c (display_mode_line): Use x_implicitly_set_name here.
+
+        * xterm.c (x_wm_hints): Variable deleted.  This has to be
+        per-screen.  Duh.
+        * xterm.h (struct x_display): New member: wm_hints.
+        * xterm.c (x_wm_set_window_state, x_wm_set_icon_pixmap,
+        x_wm_set_icon_position): Use F->wm_hints, rather than x_wm_hints.
+        (x_term_init): Don't initialize x_wm_hints here.
+        * xfns.c (Fx_create_frame): Instead, initialize f->x_wm_hints
+        here.
+
+        * xterm.c (x_set_text_property): Properly balance the BLOCK_INPUTs
+        and UNBLOCK_INPUTs.  And remember that VALUE is the string we want
+        to set the name to, not PROPERTY.
+
+1992-08-17  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+        * frame.c (make_minibuffer_frame): Don't set this to auto-raise by
+        default.  It's annoying.
+
+        * frame.c (make_minibuffer_frame): Set the prev field of the
+        minibuffer window on a minibuffer-only frame to Qnil, rather than
+        having it point to itself.  This confuses code (Fprevious_window
+        and change_window_height, for example), and is only an attempt to
+        support a convention that can't really be used in Emacs 19 anymore.
+        * window.h: Document the fact that we can no longer assume that
+        the minibuffer's previous window is the root window, since a
+        minibuffer window in a minibuffer-only frame has a prev field of
+        nil.
+        * frame.h [not MULTI_FRAME] (FRAME_ROOT_WINDOW): Define this by
+        reference to the_only_frame.root_window, rather than by assuming
+        that minibuf_window->prev is the root window.  While this is true
+        in the non-multi-frame case, we want to discourage this assumption
+        in code.
+        * dispnew.c [not MULTI_FRAME] (Fredraw_display): Use
+        FRAME_ROOT_WINDOW instead of minibuf_window->prev.
+        * xdisp.c (redisplay, init_xdisp): Same.
+        * window.c (Fset_window_configuration): Removed #if 0'd code which
+        assumes that minibuf_window is on the same frame as the window
+        configuration.  Removed special case for windows whose prevs
+        point to themselves.
+
+        * window.c (Fset_window_configuration): Rename the argument from
+        ARG to CONFIGURATION, so it matches the docstring.  The
+        make-docfile program cares.
+
+        * window.c [MULTI_FRAME] (syms_of_window): Don't staticpro
+        minibuf_window; the frame list will take care of it.
+
+        * xterm.h (HAVE_X11R4): Since we can autodetect this, and can
+        write code more likely to be future-compatible, define this when
+        appropriate.
+        * xterm.c (x_set_text_property): Define this appropriately for
+        X11R3 and X11R4.
+
+        * xterm.c (x_set_text_property): Make this take a Lisp_Object
+        string as an argument, rather than a pointer and a length.
+        * xfns.c (x_set_name): Caller changed.
+
+        * xfns.c (x_get_arg): Accept a new type - symbol.  If we've
+        retrieved a string from the xrdb database and the user wants a
+        symbol, intern it.
+        (Fx_create_frame): Use the symbol type here.
+
+        * xfns.c (x_figure_window_size, x_icon, Fx_create_frame): Use
+        values from enum resource_types for the last arg to x_get_arg,
+        instead of passing numbers.
+
+        * xfns.c (Fx_create_frame): When setting up the scroll bars, use
+        the type parameter to x_default_parameter, rather than prefixing
+        the resource name with a question mark.
+
+        * xfns.c [not HAVE_X11] (Fx_create_frame): The resource which
+        determines whether or not to use a bitmapped icon is called
+        "IconType", not "BitmapIcon".  Update this.
+
+1992-08-15  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+        * xterm.c: Doc fixes.
+
+        More SYSV portability changes from Eric Raymond:
+
+        * xterm.c [USG5]: Don't include <sys/types.h>.
+
+        * xterm.c (x_make_frame_invisible): Instead of calling XWithdraw
+        window, which isn't widely available, write out what it does,
+        since that's not much.
+        (x_iconify_frame): Explicitly perform both the X11R3 and X11R4
+        methods for iconification; don't use XIconifyWindow, since that's
+        not present in R3.
+        
+        * xterm.c (x_wm_set_size_hint): Don't bother setting the
+        base_width and base_height members; their function is performed
+        just as well by the min_width and min_height members, and if we
+        use XSetNormalHints instead of XSetWMNormalHints, we can be
+        compatible with R3.
+
+        * xterm.c (x_error_handler): There is no way to invoke the default
+        error handler which works on all versions of X11, so don't bother;
+        call XGetErrorText and print the message ourselves.
+
+        * xterm.c (x_term_init): Don't use MAXHOSTNAMELEN; this isn't
+        defined on all systems.  Since we only use that as an initial
+        guess anyway, it's not very important.
+
+1992-08-14  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+        * abbrev.c (Fexpand_abbrev): If pre-expand hook changes the buffer,
+        assume that means we "did an expansion".
+
+        * cmds.c (internal_self_insert): Ignore value of Fexpand_abbrev;
+        instead, check whether buf is modified when it returns.
+
+1992-08-14  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+        Applied SYSV portability changes from Eric Raymond:
+
+        * xrdb.c [USG5]: Define SYSV, and then include <unistd.h>.
+        Apparently, Xlib.h include string.h if SYSV is defined, and
+        strings.h if not.
+        Don't include <sys/types.h>; just declare getuid to return an
+        int.  Big deal.
+        (MAXPATHLEN): If this is not defined by the system's include
+        files, give it a value of 256.
+        (get_user_db): Fetch the defaults directly from the display
+        structure, rather than using XResourceManagerString; that
+        function doesn't exist in the older versions of X.
+
+        * xterm.c (x_set_text_property): New function.
+        * xfns.c (x_set_name): Use it instead of XSetWMName and
+        XSetWMIconName.
+
+        * xfns.c (select_visual): Fetch the visual id directly from v;
+        don't call XVisualIDFromVisual, since that function is not
+        available in earlier versions of X.
+
+        * term.c (term_get_fkeys): Some systems define `static' to be the
+        empty string, which means that you can't have constant
+        initialized arrays inside a function.  So move the `keys' array
+        outside of the function.
+        * xdisp.c (decode_mode_spec): Same deal, with lots_of_dashes.
+        * xfns.c (x_make_gc): Same deal, regarding cursor_bits.
+
+        * term.c (keys): Include definitions for "K2" (the center key on
+        an IBM keypad), "F1" (F11), and "F2" (F12).  Handle "k0" and "k;"
+        specially; see the code for details.
+
+        * term.c (clear_end_of_line): Remember that on some systems,
+        "static" gets defined to be the null string, so we can't declare
+        an array to be static and then initialize it.  Since the array in
+        question (buf) is only one element long, just make it a scalar
+        rather than an array; it can then be initialized, even if it's
+        not static.
+
+        * systime.h [not HAVE_TIMEVAL] (EMACS_USECS, EMACS_SET_USECS):
+        Don't forget to define dummy versions of these.
+
+        * systime.h [USE_UTIME]: time_t is a typedef, not a struct.
+        Don't prefix it with `struct'.
+
+        * systerm.h (EMACS_SET_TTY_PGRP): When there doesn't seem to be
+        any way to do this, don't forget to give it a dummy definition.
+
+        * sysdep.c (select): There's no need to cast the return value of
+        signal anymore, since we have the SIGTYPE macro defined.
+
+        * sysdep.c (read_input_waiting): When scanning for quit
+        characters, use the value of quit_char, rather than assuming that
+        C-g is the quit character.  And don't forget to declare i.
+
+        * sysdep.c [USG5]: Don't include fcntl.h.
+
+        * s/usg5-3.h: Eric Raymond writes:
+        Define HAVE_SELECT and BSTRINGS only if HAVE_X_WINDOWS is on,
+        because that means we'll be linking in the shared libraries
+        containing the BSD emulations.  Teach the file about the shared
+        libraries necessary to link X programs, because AT&T doesn't
+        supply static libraries for X.  Also, fix the incorrect assertion
+        that -lg cannot be used with SVr3.  Finally, force USE_UTIMES and
+        BROKEN_TIOCGWINSZ.  (Note for the future; there may be a
+        utimes(2)) emulation lurking in the X shared libraries.)
+
+        * s/usg5-4.h (USE_UTIME): Remove this definition; the C library
+        still doesn't have utimes.
+
+        * ralloc.c (get_bloc): When initializing new_bloc->variable, cast
+        NIL to (POINTER *).
+        (malloc_init): Give warning if sbrk returns zero.  Wonder what
+        that's supposed to mean.
+
+        * process.c (process_send_signal): Don't send SIGTSTP if the
+        system doesn't have that facility.
+
+        * process.c: [USG5] Don't include <fcntl.h>.
+        [USG] Don't bother including <termios.h>, <termio.h>, or
+        <fcntl.h>; systerm.h takes care of all that.
+        Remove the "mis;tak-+;;" line from the code; apparently this
+        section of code does get used.
+
+        * minibuf.c (Fread_from_minibuffer): Put this function's doc
+        string into a comment; it's too long for the PCC preprocessor.
+        Rah.
+        (Fcompleting_read): Same deal.
+
+        * keyboard.c (init_keyboard): Changed "#endif SIGIO" to
+        "#endif /* SIGIO */"
+        * mocklisp.c (Fml_substr): Same sort of thing.
+        * process.c (wait_reading_process_input): Same.
+
+        * floatfns.c (Fexpm1, Flog1p): Function removed; it's not widely
+        available, and hardly vital.
+        (syms_of_floatfns): Adjusted appropriately.
+
+        * floatfns.c (Flog): Accept optional second arg, being the base
+        for the logarithm.
+        [USG] (Flogb): Define this in terms of Flog.
+
+        * data.c [USG] (Frem): Call fmod, rather than drem.  Rah.
+
+        * emacs.c [USG5]: Don't #include <fcntl.h> for these systems.
+
+        * alloc.c (Fmake_marker): Removed the test for being called from a
+        signal handler.  The original bug is probably gone, the test
+        wasn't written portably, and it should probably go somewhere else
+        anyway - say, funcall or eval.
+
+        End of changes from Eric Raymond.
+
+        * xfns.c (Fx_create_frame): Make the default for the icon-type
+        parameter nil, not t.  It seems to cause problems with some X
+        servers.
+
+        * lisp.h (DEFVAR_PER_BUFFER): Add new argument, TYPE, to help
+        check the types of buffer-local variable slots.
+        * buffer.c (syms_of_buffer): Call DEFVAR_PER_BUFFER with the new
+        TYPE argument.
+        * abbrev.c (syms_of_abbrev): Same.
+        * buffer.c (buffer_local_types): New variable.
+        (buffer_slot_type_mismatch): New function.
+        * buffer.h (buffer_local_types): New extern declaration.
+        * data.c (store_symval_forwarding): When storing through a
+        Lisp_Buffer_Objfwd, check if the slot requires a particular type,
+        and report an error if the types clash.
+        * lread.c (defvar_per_buffer): Support new TYPE argument, by
+        setting the appropriate slot in buffer_local_types.
+
+1992-08-13  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+        * window.c (window_loop): This used to keep track of the first
+        window processed and wait until we came back around to it.  Sadly,
+        this doesn't work if that window gets deleted.  So instead, use
+        Fprevious_window to find the last window to process, and loop
+        until we've done that one.
+
+        * window.c [not MULTI_FRAME] (init_window_once): Don't forget to
+        set the `mini_p' flag on the new minibuffer window to t.
+
+        * window.c (Fwindow_at): Don't check the type of the frame
+        argument.
+
+        * window.c [not MULTI_FRAME] (window_loop): Set frame to zero,
+        instead of trying to decode it.
+
+        * frame.h [not MULTI_FRAME] (the_only_frame): Put a comment above
+        this indicating that it's not GCPRO'd.  Put parens around some of
+        the FRAME_* macros' definitions.
+        [not MULTI_SCREEN] (Fselected_frame): New function.
+
+        * frame.h [not MULTI_FRAME] (FRAME_ROOT_WINDOW): Define this in
+        terms of minibuf_window, rather than by reference to
+        the_only_frame.
+        * window.c (init_window_once): Initialize minibuf_window before
+        FRAME_ROOT_WINDOW, so the latter actually points to something.
+
+        * keyboard.c (Fexecute_mouse_event): dyked-out function deleted.
+        We're not going to use this mouse interface.
+        (Vmouse_window, Vmouse_event, Vmouse_event_function,
+        Vmouse_left_hook, Vmap_frame_hook, Vunmap_frame_hook,
+        Vmouse_motion_handler): Variables deleted; they were to be used by
+        Fexecute_mouse_event.
+        (syms_of_keyboard): Same.
+        (command_loop_1): Remove dyked-out code to support
+        Fexecute_mouse_event.
+        (read_char): Same.
+
+        * keyboard.c (Vlast_event_frame): Don't define this window if
+        MULTI_FRAME is not #defined.
+        (syms_of_keyboard): Same.
+        (kbd_buffer_store_event): Don't try to work with Vlast_event_frame
+        if MULTI_FRAME is not #defined.
+        (kbd_buffer_get_event): Same.
+
+        * keyboard.c (Fdiscard_input): Removed dyked-out code from when
+        unread_command_char's quiescent value was -1, not nil.
+
+        * frame.c (make_frame): Stop passing zero to make_window; it's not
+        expecting any arguments.
+
+1992-08-12  Jim Blandy  (jimb@albert.gnu.ai.mit.edu)
+
+        * unexsunos4.c: Deleted "$Log" header in comments at top of file;
+        this was beginning to grow RCS hair, which we don't want.
+        * xmenu.c: Same deal.
+
+1992-08-11  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+        * fileio.c (Fread_filename): Don't add one here.
+        * minibuf.c (Fcompleting_read): Instead, stop subtracting one
+        here, so this function lives up to its doc string, which I think
+        specifies an okay way to work.
+
+        * doc.c (Vdata_directory): Removed; this is declared in callproc.c.
+        (syms_of_doc): Initialization removed.
+
+        * xfns.c (x_get_arg): Return Qunbound for an unspecified
+        resource, not nil.  That way, we can tell the difference between a
+        false resource and an unspecified resource.
+        (x_default_error): Use DEFLT if x_get_arg returns Qunbound, not Qnil.
+        (x_figure_window_size, x_icon, Fx_create_frame): Deal with
+        Qunbound and Qnil properly.
+
+        * xfns.c (Fx_create_frame): Pass the correct number of arguments
+        to x_set_font.
+
+        * xfns.c [not HAVE_X11] (Fx_create_frame): Delete section that's
+        only included if we *do* have X11.  Blind patching.
+
+        * xfns.c (x_icon): Rewritten to call x_wm_set_icon_position and
+        x_wm_set_window_state instead of calling XSetWMHints directly.
+        * xterm.c (x_wm_hints): New variable.
+        (x_wm_set_window_state, x_wm_set_icon_pixmap,
+        x_wm_set_icon_position): Use x_wm_hints.
+        (x_term_init): Set the `input' field of x_wm_hints, and its flag.
+
+        * xterm.c (x_text_icon): Call x_wm_set_icon_pixmap with a pixmap
+        of zero, to clear the pixmap.
+        (x_wm_set_icon_pixmap): Accept this protocol; if pixmap is zero,
+        specify no pixmap for the icon.
+
+        * xfns.c (x_default_parameter): Don't call store_frame_param here;
+        it's already taken care of by x_set_frame_parameters.
+
+        * xfns.c (Fx_create_frame): Check for the `icon-type',
+        `auto-raise', and `auto-lower' parameters. Have `icon-type'
+        default to t, indicating that we want the nifty gnu in our icons.
+        (Qauto_lower): New symbol.
+
+        * xfns.c (x_set_icon_type): UNBLOCK_INPUT before reporting the
+        error, not after.  error doesn't return, sklitch-brain.
+
+        * xterm.c (x_set_window_size): Call check_frame_size to make sure
+        that the requested dimensions are within acceptable limits.
+        Store the new size information in the frame structure.
+
+        * xfns.c (x_set_frame_parameters): Properly recognize changes to
+        the height of the frame.  Recognize changes of the frame's
+        position.
+
+        * xfns.c (x_set_frame_parameters): Iterate over ALIST while the
+        current element is cons, not while it's non-nil.
+        (syms_of_xfns): Call init_x_parm_symbols after interning all the
+        other atoms; init_x_parm_symbols expects Qx_frame_parameter to be
+        initialized.
+
+1992-08-10  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+        * xfns.c (Qbackground_color, Qborder_color,  Qborder_width,
+        Qcursor_color,  Qfont,  Qforeground_color,  Qgeometry,
+        Qhorizontal_scroll_bar,  Qicon_left,  Qicon_top,  Qiconic_startup,
+        Qinternal_border_width,  Qleft,  Qmouse_color,  Qparent_id,
+        Qsuppress_icon,  Qsuppress_initial_map,  Qtop,  Qundefined_color,
+        Qvertical_scroll_bar,  Qwindow_id,  Qx_frame_parameter): New
+        symbols, with lisp code to rebuild syms_of_xfns.
+        (syms_of_xfns): Initialize and staticpro them.
+        (Qheight, Qminibuffer, Qname, Qnone, Qonly, Qwidth,
+        Qunsplittable): Add extern declaration for these.
+        (x_init_parm_symbols): Don't initialize Qx_frame_parameter here;
+        it's done in syms_of_xfns.
+        (x_default_parameter): Change the argument char *PROPNAME into a
+        Lisp_Object PROP; let the caller take care of interning the atom.
+        (Fx_geometry, x_figure_window_size, x_icon, Fx_create_frame): Use
+        the new Q... variables, instead of interning things.
+
+        * frame.c (Qheight, Qicon, Qmodeline, Qname, Qnone, Qonly,
+        Qunsplittable, Qwidth, Qx): New symbol, with lisp code to rebuild
+        syms_of_frame.
+        (syms_of_xfns): Initialize and staticpro them.
+        (Fframep, Fframe_visible_p, Fframe_parameters):  Use
+        the new Q... variables, instead of interning things.
+        (store_in_alist): Change the argument char *PROPNAME into a
+        Lisp_Object PROP; let the caller take care of interning the atom.
+
+        * frame.c (Fframe_visible_p): Doc fix.
+
+        * frame.c (Fframe_parameters): When figuring the `minibuffer'
+        parameter, if FRAME doesn't have a minibuffer, return `none', not
+        nil.  If it does have a minibuffer with other windows, return the
+        window.
+
+        * frame.c (Fmodify_frame_parameters): Don't write out the loop for
+        processing X frame parameters here; do it in the x specific code.
+        Call the function which deals with this stuff
+        x_set_frame_parameters, not x_set_frame_parameter.
+        * xfns.c (x_set_frame_param): Replaced by x_set_frame_parameters.
+        (x_set_frame_parameters): Process the alist of parameters here.
+        Notice `width', `height', `top', and `left' parameters.
+        Hold off changing the frame size and position until the end, so we
+        can do both parameters at once when they are both specified.
+        (x_default_parameter): Call x_set_frame_parameters, not
+        x_set_frame_param.
+
+        * frame.c (Fmake_frame_visible, Fmake_frame_invisible,
+        Ficonify_frame, Fframe_parameters, Fmodify_frame_parameters,
+        Fset_frame_height, Fset_frame_width, Fset_frame_size,
+        Fset_frame_position): Place clauses controlled by FRAME_X_P inside
+        `#ifdef HAVE_X_WINDOWS ... #endif' clauses.
+
+        * frame.c (Fset_frame_position): Doc fix.
+
+        * dispnew.c (Fredraw_frame): Call clear_frame_records before
+        calling update_end, so that x_display_box_cursor can rely on the
+        contents of f->current_glyphs.
+
+        * xfns.c (x_figure_window_size): Indicate that this function
+        returns an int, rather than just leaving it unstated.
+
+        * xterm.c (x_wm_set_size_hint): Don't try to set the base_height
+        and base_width elements of size_hints if PBaseSize is not
+        #defined.  Set the minimum frame size according to the information
+        returned by check_frame_size.
+
+        * window.h (MIN_SAFE_WINDOW_HEIGHT, MIN_SAFE_WINDOW_WIDTH): Macros
+        removed.
+        (check_frame_size): New extern declaration.
+        * window.c (MIN_SAFE_WINDOW_HEIGHT, MIN_SAFE_WINDOW_WIDTH): Macros
+        defined here now.
+        (check_frame_size): New function.
+        * dispnew.c (change_frame_size): Call check_frame_size here,
+        rather than writing out its code.  Don't declare newheight and
+        newwidth to be register variables, since we take their address.
+
+        * bytecode.c (Fbyte_code): When metering the Bcall opcodes, make
+        sure the count on the symbol's `byte-code-meter' property does not
+        overflow.
+
+        * bytecode.c (syms_of_bytecode): Add a docstring for
+        byte-metering-on.
+
+1992-08-08  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+        * dispnew.c (in_display): Variable deleted; it's only ever used as
+        an unofficial parameter to change_frame_size.
+        (change_frame_size): New argument, DELAY, which when non-zero
+        indicates to delay the size change until later.  This should be
+        passed as one from signal handlers.
+        (window_change_signal): Call change_frame_size with a DELAY of 1.
+        (do_pending_window_change): Call change_frame_size with DELAY of 0.
+        * frame.c [MULTI_SCREEN] (Fset_frame_height, Fset_frame_width,
+        Fset_frame_size): Same.
+        [not MULTI_SCREEN] (Fset_frame_height, Fset_frame_width,
+        Fset_frame_size, Fset_screen_height, Fset_screen_width): Same.
+        * keyboard.c (Fsuspend_emacs): Call change_frame_size with the
+        proper arguments - the height and width are the second and third
+        arguments, not the first and second.  Pass 0 for DELAY.
+        * xfns.c (Fx_create_frame): Call change_frame_size with a DELAY of 0.
+        * xterm.c (XTread_socket, x_do_pending_expose): Call
+        change_frame_size with a DELAY of 1.
+        
+        * xterm.c (in_display): Deleted this; it's never used in xterm.c,
+        and there is another variable by the same name in dispnew.c.
+
+        * frame.c [not MULTI_SCREEN] (Fset_frame_height, Fset_frame_width,
+        Fset_frame_size, Fframe_height, Fframe_width): New functions, for
+        use when Emacs is not compiled with multiple screens.
+        [not MULTI_SCREEN] (Fset_screen_height, Fset_screen_width):
+        Functions added for backward compatibility with Emacs 18.  These
+        would be just aliases, except that the version 18 functions don't
+        take a FRAME argument.
+        [not MULTI_SCREEN] (syms_of_frame): New function, to defsubr the
+        above and add screen-height and screen-width as aliases for
+        Fframe_height and Fframe_width.
+        * emacs.c (main): Call syms_of_frame unconditionally.  When
+        MULTI_FRAME is not defined, it still provides the Fframe_width,
+        Fframe_height, Fset_frame_width, and Fset_frame_height functions.
+
+        * frame.c (Fset_frame_width): Change the size of FRAME, not of
+        selected_frame.
+
+        * frame.c (Fset_frame_width, Fset_frame_height): Declare the
+        `frame' argument to be a Lisp_Object.  It used to be undeclared.
+
+1992-08-07  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+        * dispnew.c, frame.c, frame.h, keyboard.c, scroll.c, term.c,
+        window.c, xdisp.c, xfns.c xterm.c (FRAME_IS_TERMCAP, FRAME_IS_X,
+        FRAME_HAS_MINIBUF): Renamed these to FRAME_TERMCAP_P, FRAME_X_P,
+        and FRAME_HAS_MINIBUF_P, for consistency with the rest of the
+        frame macros.
+
+        * window.h (MIN_SAFE_WINDOW_WIDTH, MIN_SAFE_WINDOW_HEIGHT): New
+        macros.
+        * window.c (check_min_window_sizes): New function.
+        (set_window_height): Call it.
+        (Fsplit_window, change_window_height): Call it, instead of writing
+        out its code.
+        * dispnew.c (change_frame_size): If newlength or newwidth are too
+        small (according to the value of MIN_SAFE_WINDOW_{WIDTH,HEIGHT}),
+        force them larger.  This isn't really right, but it's better than
+        crashing.
+
+        * editfns.c (Fcurrent_time_zone): Doc fix.
+
+1992-08-06  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+        * editfns.c (Fcurrent_time_zone): Don't forget to include code to
+        signal an error when EMACS_CURRENT_TIME_ZONE is not defined.
+
+1992-08-06  Joseph Arceneaux (jla@gnu.ai.mit.edu)
+
+        * doc.c (Vdata_directory): Declared.
+        (syms_of_doc): Initialized.
+
+        * fileio.c (Fread_filename): Add 1 to the offset position for the
+        cursor when reading file names.
+
+1992-08-05  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)
+
+        * systime.h (EMACS_CURRENT_TIME_ZONE): New macro.
+        * editfns.c (Fcurrent_time_zone): New function.
+        (syms_of_editfns): defsubr it.
+
+        * keyboard.c (read_key_sequence): Clear the eighth bit of the
+        character from the key sequence, NOT the index of the character IN
+        the key sequence.  How many tries will it take to get it right?
+
+1992-08-04  Roland McGrath (roland@churchy.gnu.ai.mit.edu)
+
+        * eval.c (syms_of_eval): Doc fix for debug-on-quit.
+
+1992-08-03  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+        * callproc.c (Fcall_process): Doc fix.  Used to claim that
+        Fcall_process doesn't wait when BUFFER was nil.  It does.
+
+1992-07-30  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+        * keyboard.c (read_key_sequence): Scan for function keys when t >=
+        mock_input, not when t > mock_input.  We do want to scan for
+        function keys when t == mock_input.
+
+        * keyboard.c (read_key_sequence): Don't increment fkey_end when
+        testing to see if keybuf[fkey_end] is a meta-character.
+
+1992-07-27  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)
+
+        * Makefile.in (TAGS): Generate tags for files in ../external-lisp
+        too.
+
+1992-07-26  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+        * eval.c (find_handler_clause): For quit, don't check Vdebug_on_error.
+        (wants_debugger): Rewrite so it cannot get an error.
+
+        * callint.c (Fcall_interactively): Handle enable-recursive-minibuffers
+        property on the command, by enabling recursive minibuffers.
+        (syms_of_callint): Set Qenable_recursive_minibuffers.
+
+1992-07-24  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)
+
+        * frame.c (Fmake_frame_visible, Fmake_frame_invisible,
+        Ficonify_frame): Make the first argument optional, defaulting to
+        selected_frame.
+        (Ficonify_frame, Fmake_frame_invisible): Add interactive specs, so
+        we can bind these directly to C-z.
+
+1992-07-24  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+        * fileio.c (Fread_file_name): Use new calling convention for
+        Fcompleting_read, with history as Qfile_name_history.
+        (syms_of_fileio): Set Qfile_name_history; set the var to nil.
+        Do staticpro for the recently created Q* vars.  
+
+        * minibuf.c (read_minibuf): Two additional args histvar and histpos.
+        All calls changed.
+        (Fcompleting_read): Last arg is now HIST--(HISTVAR . HISTPOS).
+        Arg INIT can now be (INITIAL-STRING . INITIAL-POSITION).
+        Pass BACKUP_N arg to read_minibuf properly as Lisp object.      
+        (Fread_from_minibuffer): Likewise.
+        (syms_of_minibuf): Set Qminibuffer_history and staticpro it.
+
+        * eval.c (Ffuncall, Feval): Support subrs with 7 args.
+
+        * fns.c (Fyes_or_no_p): Use Fread_string, not read_minibuf.
+        * callint.c (Fcall_interactively): For 'S', use Fread_no_blanks_input
+        rather than read_minibuf.       
+
+1992-07-23  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+        
+        * minibuf.c (Vminibuffer_history_variable): New variable.
+        (syms_of_minibuf): Define variable minibuffer-history-variable. 
+        (read_minibuf): Push the string on specified history list.
+        
+1992-07-23  Roland McGrath  (roland@churchy.gnu.ai.mit.edu)
+
+        * Makefile.in (doall, doxemacs, dotemacs): Put quotes around CC=${CC}.
+        Don't include $(MAKEOVERRIDES); that is always implicit.
+
+1992-07-22  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)
+
+        * keyboard.c (read_key_sequence): If we have read a
+        meta-character, prefix it with meta_prefix_char before looking it
+        up in the function key keymap.
+
+        * lread.c (Fread_char_exclusive): Code this with a do-while loop,
+        not a while loop with its body repeated.
+
+        * lread.c (Fread_event): Don't make this function's definition
+        conditional on X-windows.  It ought to be there no matter how
+        Emacs was built.
+        (syms_of_lread): Don't make its defsubr conditional either.
+
+        * lread.c (Fread_char): Doc fix.
+
+        * fileio.c (find_file_handler): It's called
+        Vfile_name_handler_alist, not Vfile_handler_alist.
+        (Fwrite_region): Declare the variable named `handler'.
+        (Fverify_visited_file_modtime): Use `b->filename', not `filename'.
+        (Fset_visited_file_modtime): Declare the variable named `handler'.
+        * dired.c (Fdirectory_files, Ffile_name_completion): Use
+        `dirname', not `filename'.
+        (Qfile_attributes): New variable.
+        (syms_of_dired): Initialize it.
+
+        * xselect.c (Fx_own_selection): If we're trying to set
+        cut-buffer0, and the value is too large for the X server (as
+        indicated by the max_request_size member of the X Display), just
+        set the buffer to the empty string, and return nil.
+
+1992-07-21  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+        * search.c (fast_string_match): New function.
+        * fileio.c (find_file_handler): New function.
+        (Fcopy_file, Fmake_directory, Fdelete_directory, Fdelete_file):
+        (Frename_file, Fadd_name_to_file, Fmake_symbolic_link):
+        (Ffile_exists_p, Ffile_executable_p, Ffile_readable_p, Ffile_symlink_p)
+        (Ffile_writable_p, Ffile_directory_p, Ffile_accessible_directory_p):
+        (Ffile_modes, Fset_file_modes, Ffile_newer_than_file_p):
+        (Fwrite_region, Fverify_visited_file_modtime):
+        Use find_file_handler; call the handler and return.
+        (Finsert_file_contents): Use find_file_handler;
+        cannot just return after the handler, but must handle VISIT.
+        (syms_of_fileio): Set up Qcopy_file, etc.       
+        * dired.c (Fdirectory_files, Ffile_name_completion):
+        (Ffile_name_all_completions, Ffile_attributes):
+        Use find_file_handler; call the handler.
+        (syms_of_dired): Set Qfile_attributes, etc.
+
+1992-07-21  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)
+
+        * xselect.c (Fx_own_selection): Initialize val to nil, so that if
+        we don't get the selection, we don't return garbage.  When setting
+        cut-buffer0, set val to the string pasted.
+
+        * xfns.c (x_set_name): If ARG is nil, set the frame's name to the
+        current x_id_name.
+        * xdisp.c (display_mode_line): If we should set the frame's name,
+        but there is only one frame currently active, call x_set_name with
+        nil as the name; this will display samething generically
+        appropriate.
+
+1992-07-20  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)
+        
+        * lread.c (isfloat_string): Recognize floats without a leading
+        integer part, noting that "e5" is a symbol, not a floating point
+        number.
+        
+        * xdisp.c (message, message1): When displaying a message, don't
+        make the minibuf frame visible unless the selected frame is also
+        visible.  This means that frames won't pop up unless the user is
+        actually interacting with Emacs.
+
+        * xdisp.c (display_mode_line): If Emacs is currently supporting
+        only one screen, don't change the title of the screen to the name
+        of the current buffer; this is only annoying in this case.  We
+        should probably think more carefully about how screens should be
+        named.
+
+1992-07-19  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+        
+        * process.c (allocate_pty): Handle PTY_OPEN.    
+        Delete system-specific alternatives to PTY_NAME_SPRINTF
+        and PTY_TTY_NAME_SPRINTF.       
+        
+1992-07-18  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+        
+        * callint.c (Fprefix_numeric_value): Fix typo: test raw, not val.
+        
+1992-07-17  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)
+
+        * xfns.c (x_window): x_set_name normally ignores requests to set
+        the name if the requested name is the same as the current name.
+        This is the one place where that assumption isn't correct; f->name
+        is set, but the X server hasn't been told.  So fake it out.
+
+        * emacs.c [sun] (main): On suns, localtime caches the value of the
+        time zone rather than looking it up every time.  This means that
+        the dumped Emacs doesn't check the value of the TZ environment
+        variable.  Call tzset before entering the editing loop to check
+        the new TZ value.
+
+1992-07-16  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)
+
+        * dired.c (Fdirectory_files): Don't forget to pass the REGP
+        argument to compile_pattern.
+        * search.c (compile_pattern): If REGP is zero, don't call
+        re_set_registers; nobody cares.
+
+        * fileio.c (auto_save_error): Pass the correct number of arguments
+        to Fsleep_for.
+
+        * lread.c: Include <ctype.h> at the top of the file, instead of
+        just before isfloat_string; read0 wants to use it too.
+
+        * process.c (Fdelete_process, Fprocess_status, Fprocess_send_region,
+        Fprocess_send_string, Fprocess_send_eof, Finterrupt_process): Doc
+        fixes.
+        
+        * process.c (Fprocess_status): Use get_process to find the process
+        denoted by the PROC argument, not Fget_process.
+
+1992-07-15  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+        * xdisp.c: Doc fix.
+
+1992-07-14  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)
+
+        * window.c (syms_of_window): Doc fix for pop-up-frames.
+
+        * frame.c (Fframe_parameters): Note that if FRAME is omitted, it
+        defaults to the selected frame.
+
+        * frame.c (Fframe_height, Fframe_width): Blocked out these
+        functions; they have no C callers, and can be written nicely in
+        lisp.
+        
+        * frame.c (Fframe_pixel_size): Function removed; there aren't
+        enough other functions available to make this useful.  We need
+        functions describing the size of the characters of a font.
+
+        * xterm.h, xterm.c, xselect.c, xmenu.c, xfns.c, xdisp.c, window.h,
+        window.c, termopts.h, termhooks.h, termchar.h, term.c sysdep.c,
+        scroll.c, screen.c, screen.h, process.c, print.c, minibuf.c,
+        lisp.h keyboard.c, indent.c, fns.c, emacs.c, dispnew.c,
+        dispextern.h, cm.h, alloc.c, config.h.in: Screens are now called
+        frames, to avoid even more confusion with X terminology than
+        Emacs's "windows" already cause.  All macros, functions, and
+        variables renamed; all uses changed.
+        * screen.c, screen.h: Renamed to frame.c and frame.h.  All
+        #includers changed.
+        * ymakefile: Adjusted appropriately.
+        * buffer.c: Doc fixes.
+
+        * xfns.c (Fx_store_cut_buffer): Reversed sense of test for non-X
+        screen.
+
+        * window.c (Frecenter): Doc fix; this function places point in the
+        middle of the current window, not the current screen.
+
+        * window.c (temp_output_buffer_show): Use WINDOW_SCREEN macro
+        instead of accessing the member directly.
+
+1992-07-13  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)
+
+        * print.c (print): Changed code which prints screen objects to use
+        the SCREEN_LIVE_P macro instead of testing the screen structure
+        directly.
+
+        * alloc.c (undo_threshold, undo_high_threshold): Variables renamed
+        to undo_limit and undo_strong_limit.
+        (Fgarbage_collect): Uses changed.
+        (syms_of_alloc): DEFVARs and docstrings changed.
+        * undo.c (truncate_undo_list): Comment adjusted.
+
+        * lread.c (read0): Allow floating-point numbers to begin with a
+        period.  `(0 .5)' denotes a list of two numbers, not a dotted pair.
+
+1992-07-11  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+        * fns.c, callproc.c: Doc fix.
+
+1992-07-10  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)
+
+        * bytecode.c (Bsymbol_function, Bfset): Removed comments saying
+        that these are no longer generated.  Jamie Zawinski's byte
+        compiler does generate them, and he's actually collected
+        statistics on how often these functions are called.
+
+1992-07-09  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)
+
+        * screen.c (store_screen_param): Clarify error message.
+
+        * xterm.c (x_make_screen_visible): Undo the change made on June
+        30; that is not the right solution.  Apparently there are three
+        states a window may be in: normal, iconified, and invisible.
+
+1992-07-08  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)
+
+        * eval.c (Fmacroexpand): Code cleaned up; there's no need to
+        handle forms like ((macro lambda ...) ...) specially.
+
+        * fileio.c (Finsert_file_contents): Signal an error if we're asked
+        to read from a named pipe.
+
+1992-07-07  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)
+
+        * m/*.h (SIGN_EXTEND_CHAR): Removed these definitions.  The only
+        place they were used is in regex.c, and nowadays that has its own
+        definition, which works for any machine.  The definitions in the
+        machine description files usually didn't work if given an unsigned
+        character as an argument, anyway.
+
+1992-07-04  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+        * buffer.c: Doc fix.
+
+1992-07-02  Joseph Arceneaux  (jla@churchy.gnu.ai.mit.edu)
+
+        * minibuf.c (Fdisplay_completion_list): Declared new variables
+        used in rms' previous change.
+
+1992-07-02  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+        * minibuf.c (Fdisplay_completion_list): Handle non-buffer stream.
+
+1992-07-01  Roland McGrath  (roland@churchy.gnu.ai.mit.edu)
+
+        * window.c (Fdisplay_buffer): Add interactive spec.
+
+1992-06-30  Joseph Arceneaux  (jla@churchy.gnu.ai.mit.edu)
+
+        * mem_limits.h: EXCEEDS_ELISP_PTR declared here.
+        * ralloc.c: No longer declared here.
+        * vm-limit.c: Nor here.  Also, include "lisp.h" before
+        "mem_limits.h" and additionally include "config.h".
+
+1992-06-30  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+        * xterm.c (x_make_screen_visible): Don't de-iconify the window;
+        iconification is orthogonal to visibility.
+
+        * emacs.c (syms_of_emacs): Change docstring for `kill-emacs-hook'
+        to describe it as a hook, not as a single function.
+
+1992-06-29  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+        * minibuf.c (Fread_no_blanks_input): Corrected maximum number of
+        arguments from one to two.
+
+        * emacs.c (Vkill_emacs_hook): Declare this here; it should have a
+        docstring, so we might as well DEFVAR it.
+        (syms_of_emacs): initialize it, and DEFVAR_LISP it with an
+        appropriate docstring.
+
+1992-06-28  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+        * lread.c (Feval_buffer): Make the DEFUN match the C argument
+        list; this takes two optional arguments, not just one.
+
+        * lisp.h (Lisp_Buffer_Local_Value): Comments neatened.
+
+        * data.c (Fset): Fixed conditional which tests whether the cache
+        is invalid.  It used to be pretty munged, and would always declare
+        the cache invalid for Lisp_Buffer_Local_Value variables.  Now it
+        declares the cache invalid if the buffer is wrong (obviously), of 
+
+1992-06-27  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+        * data.c (Fset): Comments reformatted for readability.
+
+        * xterm.c (last_mouse_movement_time): New variable.
+        (note_mouse_position): Set it.
+        (XTmouse_position): Return its current value as the position's
+        timestamp.
+
+        * keyboard.c (Qvertical_split): Renamed to `vertical-line',
+        since the window arrangement is actually referred to as a
+        `horizontal split.'
+        (make_lispy_event, make_lispy_movement, syms_of_keyboard): Uses
+        renamed here.
+        keyboard.h (Qvertical_split): Extern declaration changed here.
+        window.c (Fcoordinates_in_window_p): Changed this to return
+        `vertical-line' at the appropriate times, rather than
+        `vertical-split'.
+
+        * window.c (Fcoordinates_in_window_p): Put symbol names in
+        opposing single quotes - `vertical-split', for example.
+
+        * fileio.c (Fexpand_file_name): Don't signal an error if USERNAME
+        in a "~USERNAME/..." filename isn't a real user; just leave the
+        "~USERNAME" unchanged.
+
+        * fileio.c (Fmake_symbolic_link): Rename argument `NEWNAME' to
+        `LINKNAME', to conform with the docstring.
+
+        * Makefile.in (CPP): Pass `-Is -Im' to CPP, to make sure that
+        machine- and system-dependend files can include each other
+        properly.
+        * ymakefile (CFLAGS): Add those directories to the #include path
+        here too.
+
+        * Makefile.in (xmakefile): Build this via a temporary file, so
+        that if preprocessing fails we don't nuke the xmakefile.
+
+        * fileio.c: There are two versions of Fexpand_file_name defined
+        here; the latter is inside a `#if 0' clause.  Change its DEFUN to
+        a DEAFUN, so that its docstring doesn't make it into the DOC file
+        and supercede the real docstring.
+
+        * callint.c (Fcall_interactively): For the 'K' interactive spec,
+        set varies[i] to -1, indicating that the mouse click should be
+        quoted if the function makes it into the command history, and that
+        this argument by itself does not qualify the command to be
+        recorded in the history.
+
+1992-06-26  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+        * data.c (Frem): The drem function will sometimes return a
+        negative number.  If it does, add the divisor to it, to make it
+        positive.
+
+        * screen.c: Put '#ifdef MULTI_SCREEN' after the inclusion of
+        config.h.
+
+        * window.c (Fpos_visible_in_window_p): Remember to apply XSCREEN
+        to w->screen before applying SCREEN_WIDTH.
+
+        * screen.h [not MULTI_SCREEN] (last_nonminibuf_screen): Removed
+        #definition of this; it's confusing when debugging.
+        * screen.c (last_nonminibuf_screen): Variable moved from here...
+        * dispnew.c (last_nonminibuf_screen): to here, beside
+        selected_screen.  They should both exist, even if the multi-screen
+        support is not present.
+
+        * dispnew.c [not MULTI_SCREEN] (the_only_screen): New variable.
+        Instead of having the non-multi-screen version of Emacs refer to
+        lots of different variables scattered hither and yon, we'll just
+        declare this new variable, of type `struct screen', and define the
+        single-screen versions of the `SCREEN_foo' macros to reference its
+        elements.  This avoids conflicts between names of local variables
+        and names of global variables describing the screen, and simplifies
+        some of the differences between the multi-screen and single-screen
+        cases.
+        * screen.h (enum output_method, struct screen): Removed these from
+        the `#ifdef MULTI_SCREEN' conditional.
+        * screen.h [not MULTI_SCREEN] (the_only_screen): extern
+        declaration for it here.
+        [not MULTI_SCREEN] (SCREEN_CURRENT_GLYPHS, SCREEN_DESIRED_GLYPHS,
+        SCREEN_TEMP_GLYPHS, SCREEN_HEIGHT, SCREEN_WIDTH,
+        SCREEN_NEW_HEIGHT, SCREEN_NEW_WIDTH, SCREEN_CURSOR_X,
+        SCREEN_CURSOR_Y, SCREEN_ROOT_WINDOW, SCREEN_INSERT_COST,
+        SCREEN_DELETE_COST, SCREEN_INSERTN_COST, SCREEN_DELETEN_COST,
+        SCREEN_MESSAGE_BUF, SCREEN_SCROLL_BOTTOM_VPOS): Macros changed to
+        refer to the_only_screen.
+        * dispnew.c [not MULTI_SCREEN] (one_screen_cursX,
+        one_screen_cursY, one_screen_current_glyphs,
+        one_screen_desired_glyphs, one_screen_temp_glyphs,
+        delayed_screen_width, delayed_screen_height): Variables
+        deleted; they're all now kept in the_only_screen.
+        * xdisp.c [not MULTI_SCREEN] (message_buf): Variable deleted; same
+        fate.
+        * term.c [not MULTI_SCREEN] (one_screen_width, one_screen_height):
+        Variables deleted; same fate.
+        * screen.h [not MULTI_SCREEN]: extern declarations for the above
+        variables removed.
+        * window.c [not MULTI_SCREEN] (root_window): Variable deleted.
+        [not MULTI_SCREEN] (init_window_once): Use SCREEN_ROOT_WINDOW to
+        refer to the root window, instead of referring to it directly.
+        * window.h [not MULTI_SCREEN] (root_window): extern declaration
+        removed.
+        * scroll.c [not MULTI_SCREEN] (insert_line_cost, delete_line_cost,
+        insert_n_lines_cost, delete_n_lines_cost): Variables deleted; same
+        fate.
+
+        * dispnew.c [not MULTI_SCREEN] (cursX, cursY): Renamed to
+        `one_screen_cursX' and `one_screen_cursY'.
+        * screen.h [not MULTI_SCREEN] (cursX, cursY, SCREEN_CURSOR_X,
+        SCREEN_CURSOR_Y): extern declarations and macros changed
+        accordingly.
+
+        * term.c [not MULTI_SCREEN] (screen_width, screen_height): Renamed
+        to `one_screen_width' and `one_screen_height', so as not to
+        conflict with local variables when referenced by the `SCREEN_foo'
+        macros.
+        * screen.h [not MULTI_SCREEN] (screen_width, screen_height):
+        extern declarations changed accordingly.
+        * termchar.h (screen_width, screen_height): extern declarations
+        deleted.  Everyone should go through the `SCREEN_foo' macros.
+        (SCREEN_WIDTH, SCREEN_HEIGHT): Changed accordingly.
+
+1992-06-25  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+        * callint.c (Fcall_interactively): When making a copy of the spec
+        string, cast the return value of `alloca' to `unsigned char *',
+        not `char *', to match the type of `string'.
+
+        * xselect.c (Fx_own_selection): Cast XSTRING (string)->data to a
+        char *, so it can be comfortably passed to XStoreBytes.
+
+        * filelock.c (strcpy): Declare this to return char *.
+
+1992-06-24  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+        * dispnew.c (current_glyphs, desired_glyphs, temp_glyphs): Renamed
+        to have the prefix `one_screen_', so that the screen macros can
+        refer to them without conflicting with local variables.
+        * screen.h [not MULTI_SCREEN] (SCREEN_CURRENT_GLYPHS,
+        SCREEN_DESIRED_GLYPHS, SCREEN_TEMP_GLYPHS): Changed accordingly.
+
+        * keyboard.c (read_key_sequence): Put the code which restarts the
+        key sequence in a `#ifdef MULTI_SCREEN' conditional.
+
+        * screen.h [not MULTI_SCREEN]: Added definitions for
+        CHECK_LIVE_SCREEN and SCREEN_FOCUS_SCREEN for the non-multi-screen
+        case.
+
+        * screen.h [not MULTI_SCREEN]: The name is
+        `SCREEN_MINIBUF_ONLY_P', not `SCREEN_IS_MINIBUF_ONLY'.
+
+        * xdisp [not MULTI_SCREEN] (Fredraw_display): Removed definition
+        here; the non-multi-screen version is already defined in
+        dispnew.c, alongside the multi-screen version.
+        (syms_of_xdisp): Don't try to defsubr Sredraw_display; it doesn't
+        exist.
+
+        * lread.c (Fread_char_exclusive): Remove this from the `#ifdef
+        HAVE_X_WINDOWS' conditional; it is appropriate in any context.
+
+        * eval.c (Fsignal): Put call to TOTALLY_UNBLOCK_INPUT under the
+        protection of a `#ifdef HAVE_X_WINDOWS' conditional.
+
+        * keyboard.c (kbd_buffer_get_event): Expect *mouse_position_hook
+        to return the timestamp as an unsigned long, not a lisp_Object.
+        This matches the change made to `struct input_event'.
+        (make_lispy_movement): Change argument TIME to an unsigned long.
+        * xterm.c (XTmouse_position): Change TIME argument to a pointer to
+        an unsigned long.
+        * termhooks.h (mouse_position_hook): Doc fix.
+        * term.c (mouse_position_hook): Doc fix.
+
+        * termhooks.h (struct input_event): If MULTI_SCREEN is defined,
+        declare the .screen element to be `struct screen *'; otherwise,
+        declare it to be `int'.  See the comment in the file for why I've
+        done this obviously wrong thing.
+
+        * print.c (printbufidx): Doc fix.
+        * xdisp.c (message_buf_print): Doc fix.
+
+        * dispextern.h (message_buf_size): Variable deleted; it's no
+        longer used, since the message buffer is always the width of the
+        screen.
+
+        * screen.h [not MULTI_SCREEN] (message_buf): Add extern
+        declaration for it here.
+        (message_buf_print): Added extern declarations here for both the
+        MULTI_SCREEN and non-MULTI_SCREEN cases.
+        * dispextern.h (message_buf, message_buf_print): Deleted extern
+        declaration for these here.  It should never be used directly; it
+        should always be used through the SCREEN_MESSAGE_BUF macro.
+
+        * dispnew.c (temp_glyphs): Added back this variable declaration;
+        screen.h and various other places referred to this; where did it
+        go?
+        * screen.h [not MULTI_SCREEN] (temp_glyphs, desired_glyphs,
+        current_glyphs): Add extern declarations for these.
+
+        * dispnew.c (cancel_my_columns): Use SCREEN_DESIRED_GLYPHS macro,
+        instead of assuming that a SCREEN_PTR is actually a pointer to
+        something; it isn't if we're not using any of the screen support.
+        Remove the variable `screen', and find the value for
+        `desired_glyphs' directly.
+        * xdisp.c (echo_area_display): Use the SCREEN_DESIRED_GLYPHS macro
+        to find screen's desired cursor position, instead of assuming that
+        a SCREEN_PTR is a pointer to something.
+        (display_mode_line): Same.
+        * window.c (Fpos_visible_in_window_p): Use the SCREEN_WIDTH macro.
+        (replace_window): Use the SCREEN_ROOT_WINDOW macro.
+        (window_loop): Use the SCREEN_WIDTH macro.
+
+        * dispnew.c (update_screen): Enclose the statement which
+        increments `downto' in a `#ifdef HAVE_X_WINDOWS' conditional.
+
+        * screen.h [MULTI_SCREEN and not MULTI_SCREEN] (FOR_EACH_SCREEN):
+        New macro.
+        * dispnew.c (window_change_signal, do_pending_window_change): Use
+        FOR_EACH_SCREEN instead of assuming that Vscreen_list exists.
+        * window.h (root_window): Added extern declaration for this.
+
+        * screen.c: Enclose the entire file in a #ifdef MULTI_SCREEN
+        conditional.
+
+
+1992-06-23  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+        * window.c (Fset_window_dedicated_p):
+        Replaces Fset_window_buffer_dedicated.  Second arg just t or nil.
+
+1992-06-22  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+        * syntax.h (SYNTAX, SYNTAX_MATCH, SYNTAX_COMSTART_FIRST, etc.)
+        Cast character to unsigned char before indexing.
+
+1992-06-19  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+        * xterm.c (x_wm_set_size_hint): Set size_hints.flags to indicate
+        that we are providing the base_width and base_height data.
+
+        * xfns.c (Fx_create_screen): Default the internal border width to
+        2; this matches XTerm.
+
+        * syntax.c (Fparse_partial_sexp): Doc fix.
+
+        * syntax.c (Fparse_partial_sexp): Added phony argument list to
+        comment containing the docstring for this function, so that
+        make-docfile.c will get the right arguments.
+
+        * xfns.c (x_set_name): Don't go through the X11 brouhaha to set
+        the name unless we're actually setting it to something different
+        from the current name.
+
+1992-06-18  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+        * eval.c (syms_of_eval): Don't forget to escape the ends of the
+        lines in the docstring for `debug-on-quit'.
+
+        * keyboard.c (Fread_key_sequence): Reversed sense of CONTINUE_ECHO
+        argument - set this_command_key_count to zero iff CONTINUE_ECHO is
+        Qnil, not iff it's non-Qnil.
+
+1992-06-17  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+        
+        * search.c: Changed to remember the object in which the last
+        search was done, so that markers from match data are placed in
+        that buffer, instead of the current buffer.
+        (search_regs_from_string): Replaced with...
+        (last_thing_searched): This is either Qnil, meaning no searching
+        has been done, Qt, meaning that the last search was done in a
+        string, or a buffer object, meaning that the last search was done
+        in that buffer.
+        (syms_of_search): Initialize and staticpro last_thing_searched.
+        (Flooking_at, search_buffer): Set last_thing_searched to the
+        current buffer.
+        (Fstring_match): Set last_thing_searched to Qt.
+        (Fmatch_data): Test last_thing_searched to see if any searching
+        has been done, and construct integers or markers in the right
+        buffer.  Abort if it's not Qt, Qnil, or a buffer.
+        (Fstore_match_data): Set last_thing_searched according to the
+        things we find in LIST.
+        
+1992-06-16  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+        * fns.c (Fload_average): Document the fact that this sometimes
+        returns a list of fewer than three elements, on systems which
+        don't provide 5- and 15-minute load averages.
+
+1992-06-15  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+        
+        * xterm.c (XTread_socket): If an event arrives to a screen S,
+        don't attribute them to SCREEN_FOCUS_SCREEN (S) here.  Do that
+        synchronously, when the events are dequeued.  This keeps events
+        from being accidentally routed to the wrong screen, if we
+        temporarily redirect a screen's focus.
+        * keyboard.c (kbd_buffer_store_event): If the character being
+        stuffed is a quit character, do the SCREEN_FOCUS_SCREEN
+        redirection to it here.
+        (kbd_buffer_get_event): And do it here, before returning the
+        event.
+        
+        * eval.c (Finteractive_p): This assumed that if the function in
+        the top frame of the lisp backtrace was not a Lisp_Compiled
+        object, then Finteractive_p must have an explicit frame on the top
+        of the stack, which we could skip.  It didn't bother to follow the
+        symbol function chaining, and it would break if any C code called
+        from a non-compiled function tried to call Finteractive_p anyway.
+        Changed this to actually check if the top frame's effective
+        function is the Lisp_Subr for Finteractive_p.  This also used to
+        skip any number of frames for special forms and/or Fbytecode
+        calls.  Changed this to skip an Fbytecode frame (if present),
+        followed by any number of special form frames.
+
+1992-06-14  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+        * eval.c (struct backtrace): Doc fix.
+
+1992-06-12  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+        * m/hp300bsd.h (LOAD_AVE_TYPE): This is long, not double.
+        (LOAD_AVE_CVT): Adjusted as appropriate.
+
+        * fns.c: Moved lots of system-dependent preprocessor cruft
+        dealing with getting the load average to `getloadavg.c'.
+        (Fload_average): Guts moved to `getloadavg.c'.
+        * getloadavg.c: New file, containing the necessary mess to get the
+        load average on many different systems.  This file is supposed to
+        be Emacs-independent.
+        * ymakefile (obj): Add getloadavg.o to the list.
+        (getloadavg.o): Note that this depends on its source, and config.h.
+
+        * screen.c (Fdelete_screen): Typo in loop looking for new
+        last_nonminibuf_screen - change `screen = XCONS (screens)->cdr`
+                                     to `screens = XCONS (screens)->cdr`
+
+        * xdisp.c (echo_area_display): Don't neglect to draw all the lines
+        of the minibuffer window (or echo area) when a message is being
+        displayed.  If the minibuffer is more than one line high, they
+        should all be blanked.
+
+1992-06-10  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)
+
+        * sysdep.c [POSIX_SIGNALS] (sys_signal): Fix typo - rather than
+        calling new_action as if it were a function, call sigaction.
+
+1992-06-09  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+        * lisp.h (Qnumberp, Qnumber_or_marker_p): Declared.
+
+        * eval.c (wants_debugger): Changed NULL to NILP.
+        Who installed these calls to NULL?
+
+1992-06-09  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+        * dispnew.c (Fsit_for): Don't forget to actually set sec from ARG.
+
+        * termhooks.h (struct input_event): Doc fix - for mouse clicks, .x
+        and .y give the position in characters, not in pixels.
+
+        * keyboard.c (format_modifiers): Order the modifier letters
+        alphabetically - control, meta, shift, and up.
+
+1992-06-08  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+        * xfns.c: Move some extern decls out of #if 0, to top of file.
+
+1992-06-08  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+        * window.c (Fcoordinates_in_window_p): Docstring fix.
+
+        * buffer.c (Fother_buffer): Put a comma between arguments BUFFER
+        and VISIBLE_OK in the argument list.  Duh.
+
+        * screen.c (Fdelete_screen): Remember that s is a SCREEN_PTR *,
+        not a Lisp_Object.
+
+        * search.c (search_regs): Doc fix.
+        (compile_pattern): Take a new argument - the search register
+        structure - so we can reassure the regex routines that the
+        registers have been allocated.
+        (Flooking_at, Fstring_match, search_buffer): Changed to pass
+        &search_regs to compile_pattern.
+        (search_buffer): When we've searched for a literal string and
+        found it, make sure that the search registers are allocated before
+        stuffing the location of the search into them.
+        (Fstore_match_data): If we need to allocate more registers,
+        allocate them using re_set_registers, instead of just storing the
+        new registers and hoping that regex doesn't free them.
+
+        * search.c (Freplace_match): Doc fix.
+
+1992-06-07  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+        * screen.c (Fdeiconify_screen): Function deleted.
+        It was the same as make-screen-visible.
+
+1992-06-06  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+        * keyboard.c: Doc fix.
+
+        * floatfns.c (Fcbrt): Renamed from Fcube_root, and #if 0'd.
+
+        * lisp.h (CHECK_NUMBER_OR_FLOAT*): Use Qnumberp or Qnumber_or_marker_p.
+        * data.c (syms_of_data): Staticpro those.
+        (Qinteger_or_float_p, Qinteger_or_float_or_marker_p): Deleted.
+        (Fnumberp, Fnumber_or_marker_p): Define these always,
+        but make them work even if not LISP_FLOAT_TYPE.
+
+1992-06-05  Joseph Arceneaux  (jla@churchy.gnu.ai.mit.edu)
+
+        * config.h.in: Undefine REL_ALLOC if a system specific file
+        defines SYSTEM_MALLOC.
+
+        * sysdep.c (save_signal_handlers): Cast result of signal  to
+        avoid compiler warning.
+        * process.c (send_process): Likewise.
+
+1992-06-05  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+        
+        * keyboard.c (Fread_key_sequence): New 2nd arg CONTINUE_ECHO
+        added for the sake of universal-argument.
+        
+1992-06-04  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+

+        (x_rectangle, outline_region): Likewise.
+        (syms_of_xfns): #if 0 the defsubrs.
+
+        * dispnew.c (Fsleep_for, Fsit_for): Clean up error messages.
+
+        * eval.c, print.c, keyboard.c: Doc fix.
+
+        * xfns.c (Fx_horizontal_line): Disabled, since not documented.
+
+        * fileio.c (Fdelete_directory): Renamed from Fremove_directory.
+
+        * unexencap.c: Deinstalled (renamed to =unexencap.c)
+        since awaited papers never arrived.
+
+        * xfns.c: Doc fix.
+
+1992-06-04  Roland McGrath  (roland@geech.gnu.ai.mit.edu)
+
+        * eval.c (stack_trace_on_error, debug_on_error): Made Lisp_Objects V*.
+        (syms_of_eval): Changed DEFVAR_BOOLs to DEFVAR_LISPs.
+        (wants_debugger): New fn.
+        (find_handler_clause): Use it to look in debug-on-error and
+        stack-trace-on-error lists.
+
+1992-06-04  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+        * floatfns.c (Fbessel_*, Ferf, Ferfc, Flog_gamma): Turned off;
+        not clearly worth including.
+        (Fasinh, Facosh, Fatanh, Fsinh, Fcosh, Ftanh): Likewise.
+
+1992-06-03  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+        * minibuf.c, keyboard.c: Doc fix.
+
+        * window.c (Fwindow_at): Fix number of args--minimum 2, max 3.
+
+        * screen.c: Doc fix.
+
+1992-06-02  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+        * lread.c (Feval_buffer): Don't read any arguments, if interactive.
+
+1992-06-02  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)
+
+        * screen.c (make_screen_without_minibuffer): Apply XSCREEN to
+        Vdefault_minibuffer_screen before calling SCREEN_LIVE_P.  The
+        argument to SCREEN_LIVE_P must be a SCREEN_PTR, not a Lisp_Object.
+
+        * dispnew.c (Fsit_for): This used to compare arg with 0 and return
+        Qt immediately.  It should actually call sit_for anyway, because
+        sit_for needs to test for input and do the redisplay.
+        (sit_for): Compare sec and usec with zero here, after we've
+        looked for input and done a redisplay.
+
+        * lread.c (Feval_buffer): Use NILP, not NIL_P.
+
+1992-06-01  Joseph Arceneaux  (jla@churchy.gnu.ai.mit.edu)
+
+        * buffer.h: New macro, BUF_SET_PT.
+
+        * lread.c: New subr `eval-buffer', replaces `eval-current-buffer',
+        which is now defined in simple.el.
+
+1992-05-30  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+        * screen.c (Fdelete_screen): If we're deleting the default
+        minibuffer screen, try to find another minibuffer screen.
+
+1992-05-29  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+        * buffer.c (Fother_buffer): New optional argument VISIBLE_OK,
+        indicating that buffers currently visible in windows should not be
+        discriminated against.
+
+1992-05-28  Ken Raeburn  (raeburn@cygnus.com)
+        
+        * screen.c (Fdelete_screen): Fix bugs in walking screen list.
+        (make_screen_without_minibuffer): Signal an error if the default
+        minibuffer screen is dead.
+        
+        * xfns.c (x_set_name): Use ICCCM-conforming scheme for changing
+        window name in X11.
+        (Fx_create_screen): Likewise.
+
+1992-05-27  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+        * xselect.c: Support getting and setting the obsolete X cut
+        buffers.
+        (Qcut_buffer0): New atom, denoting the X cut buffer 0.
+        (syms_of_xselect): Initialize and staticpro it.
+        (Fx_own_selection): If TYPE is Qcut_buffer0, interpret this to
+        mean that we should set cut buffer 0 to STRING.
+        (Fx_selection_value): If TYPE is Qcut_buffer0, interpret this to
+        mean that we should retrieve the value of cut buffer 0.
+
+1992-05-21  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+        * xterm.c (construct_mouse_click): Removed extra assignment of
+        result->timestamp.
+
+        * keyboard.c (last_event_timestamp): Doc fix.
+        * xselect.c (last_event_timestamp): Declare it extern here.
+        (mouse_timestamp): Variable deleted.  last_event_timestamp is a
+        more accurate thing to use here.
+        (own_selection, get_selection_value): Use last_event_timestamp
+        instead of mouse_timestamp.
+        * keyboard.c (make_lispy_event): Pass the event's timestamp
+        through the make_number function, to assure that it is properly
+        tagged before incorporating it into the lispy event.
+        * xterm.c (construct_mouse_click): The timestamp element of a
+        struct input_event is no longer a Lisp_Object; it is now an
+        unsigned long.  So don't use XSET to assign to it.
+        (XTread_socket): Same here, in processing KeyPress events.
+
+        * keyboard.c (Fexecute_extended_command): Properly initialize
+        this_command_keys to the concatenation of the sequence that
+        invoked Fexecute_extended_command, the characters making up the
+        name of the command we're running, and a return character.
+        Previously, this code would set it to the last key typed while
+        reading the function name from the minibuffer, followed by the
+        name of the function being run.
+
+1992-05-20  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+        * xterm.c (x_display_box_cursor): Draw the cursor at curs_{x,y},
+        rather than at s->cursor_{x,y}.  If cursor_in_echo_area is set,
+        then s->cursor_{x,y} does not accurately describe the position of
+        the cursor.  However, if we're not updating, then curs_{x,y} are
+        garbage; set them from s->cursor_{x,y}.
+
+        * dispnew.c (update_screen): Check current_screen->enable and
+        current_screen_used to see if there is any text on the last line,
+        not desired_screen->{enable,used}.  When the line isn't enabled,
+        move to line SCREEN_HEIGHT (s) - 1, not SCREEN_HEIGHT (s).
+        Rearranged conditionals.
+
+        * dispnew.c (cursor_in_echo_area): Document the interpretations of
+        positive and negative values of this variable.
+
+1992-05-18  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+        * dispnew.c (Fding): If have arg, don't end a keyboard macro.
+
+1992-05-18  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+        * dispnew.c (sit_for): New function, which is a slight
+        generalization of Fsit_for; you can tell it that it's waiting for
+        input, so C-g gets handled properly.
+        (Fsit_for): Call it, instead of replicating all its guts.
+        * keyboard.c (read_char): Call sit_for instead of Fsit_for, and
+        indicate that we're awaiting keyboard input.
+
+        * dispnew.c (Fsit_for): Rename arguments to match docstring.  Use
+        NILP instead of EQ (foo, Qnil).  If nodisp is non-nil, call
+        wait_reading_process_input with do_display 0, instead of 1; this
+        will inhibit spurious redisplays when process input arrives during
+        a sit-for.
+
+        * process.c (Faccept_process_output): Pass zero as read_kbd
+        argument to wait_reading_process_input when PROC is nil, not when
+        PROC is non-nil.
+
+        * process.c (wait_reading_process_input): Declare read_kbd to be a
+        Lisp_Object, and use the tagging to tell the difference between a
+        process object and an integer.
+        * dispnew.c (Fsleep_for, Fsit_for, Fsleep_for_millisecs): Pass
+        read_kbd argument to wait_reading_process_input as a Lisp_Object.
+        * keyboard.c (kbd_buffer_get_event): Same.
+        * process.c (Faccept_process_output, send_process): Same.
+
+        * keyboard.c (read_char): Use save_getcjmp and restore_getcjmp
+        instead of doing the bcopy explicitly.
+
+        * xterm.c (XTread_socket): When handling an EnterWindow event,
+        don't bother to check waiting_for_input.  It's not necessary.
+
+        * keyboard.c (read_char): Don't clear waiting_for_input and
+        input_available_clear_time here.
+        (quit_throw_to_read_char): It's already done here.
+
+        * keyboard.c (quit_throw_to_read_char): Use
+        clear_waiting_for_input instead of clearing waiting_for_input
+        explicitly.
+
+1992-05-18  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+        * keyboard.c (read_char): Call clear_waiting_for_input instead of
+        clearing waiting_for_input and input_available_clear_time
+        explicitly.
+
+1992-05-15  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+        * ymakefile [defined (__GNUC__) and __GNUC__ > 1]: define
+        YMF_PASS_LDFLAGS so that it can deal with an empty flags argument.
+
+        * callproc.c (Fcall_process): Under VMS, a nil INFILE argument
+        means to read from "NLA0:", not "/dev/null".
+
+        * callproc.c (Fcall_process): Use nil as the value for display
+        (the fourth argument) when nargs >= 4, not when nargs >= 3.
+
+1992-05-14  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+        
+        * termhooks.h: Change timestamp from a Lisp_Object to an unsigned
+        long.
+        * keyboard.c (kbd_buffer_store_event): We don't have to apply the
+        XINT macro to the timestamp member of the event anymore.
+
+        * process.c (wait_reading_process_output): Don't turn off polling.
+
+        * sysdep.c (setpgrp_of_tty): Pass the address of pid, not pid
+        itself.
+
+        * process.c: Deleted cpp tangle for dealing with system-dependent
+        tty handling; #included "systerm.h".
+        * systerm.h: Add some of the things that were done in process.c:
+        If titan is #defined, then we should include <sys/ttyhw.h> and
+        <sys/stream.h> along with the other SYSV pty stuff.
+        If HPUX is #defined, then EMACS_HAVE_TTY_PGRP isn't true.
+        If XENIX is #defined, then we shouldn't try to use TIOCGETC.
+        * ymakefile: Note that process.o depends on systerm.h now.
+
+1992-05-13  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+        * callint.c (Fprefix_numeric_value): Value 1 for symbol other than `-'.
+
+1992-05-13  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+        * cmds.c (Fforward_line): If the buffer is empty, don't try to see
+        if it contains a newline, and moving nowhere at eob after
+        non-newline should return 1, not 0.
+
+        * search.c (scan_buffer): Doc fix.
+
+        * buffer.c (Fbuffer_disable_undo): Accept a buffer name as an
+        argument.
+
+1992-05-12  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+        * fileio.c: Include config.h first thing.       
+        
+        * keyboard.c (clear_input_pending): New subroutine.
+        * process.c (wait_reading_process_input): Make C-g really quit in
+        sit-for case.
+
+        * ymakefile (LD_SWITCH_SYSTEM): Don't use -X with GCC.
+
+1992-05-12  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+        * eval.c (Fapply): Use indirect_function, instead of doing a dumb
+        loop.
+        * keymap.c (get_keymap_1): Same.
+        * macros.c (Fexecute_kbd_macro): Same.
+
+        * buffer.c (init_buffer_once): Don't disable undos for *scratch*
+        here.  Do it in loadup.el.
+
+        * buffer.c (init_buffer_once): Doc fix.
+
+        * doc.c (Fdocumentation): After extracting the doc string from a
+        lambda or autoload expression, don't fall through to the default
+        case and signal an invalid function error; instead, do a `break'.
+
+        * doc.c (Fdocumentation): Use EQ (x, y) instead of XSYMBOL (x) ==
+        XSYMBOL (y).
+
+        * doc.c (Fdocumentation): When decyphering a function made from
+        conses, use 'else if' for the chain of alternatives instead of
+        just 'if'.  It used to be that each alternative returned, but
+        that's not true anymore.
+
+        * alloc.c (Fgarbage_collect): Don't call truncate_undo_list on
+        buffers whose undo list is 't.
+
+        * doc.c (Fdocumentation): Renamed argument `fun1' to `function',
+        so make-docstring will list argument consistently with the
+        docstring.
+
+1992-05-11  Joseph Arceneaux  (jla@churchy.gnu.ai.mit.edu)
+
+        * xterm.h: Removed definition of `RES_CLASS'.
+
+        * xfns.c (x_get_arg): Eliminated `screen_name' parameter.  No
+        longer uses screen name as X resource search component.
+        All calls to x_get_arg changed accordingly.
+        Global variable `screen_class' and #define `SCREEN_CLASS' removed.
+
+        * xterm.c (XTread_socket): Added basic structure for handling
+        various ClientMessage events, using new global variables
+        `Xatom_wm_take_focus', `Xatom_wm_save_yourself',
+        `Xatom_wm_delete_window', `Xatom_wm_configure_denied',
+        `Xatom_wm_moved'.
+        * xfns.c: Declare these variables extern.
+        (syms_of_xfns): Initialize these variables.
+
+        * xselect.c (Fx_own_selection, Fx_selection_value): New optional
+        parameter `type', to specify the selection type.
+        (syms_of_xselect): New symbols Qprimary, Qsecondary, Qclipboard
+        initialized.
+
+1992-05-11  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+        * data.c (Qcyclic_function_indirection): New error condition.
+        (indirect_function, Findirect_function): New functions.
+        (syms_of_data): Initialize Qcyclic_function_indirection, put the
+        error properties on it, and staticpro it.  Defsubr
+        Findirect_function.
+        * lisp.h (indirect_function, Findirect_function): Declare them here.
+        * callint.c (Fcall_interactively): Get symbol's function by
+        calling indirect_function, instead of just looping.
+        * doc.c (Fdocumentation): Same.
+        * eval.c (Finteractive_p, Fcommandp, do_autoload, Feval,
+        Ffuncall): Same.
+        * keyboard.c (Fcommand_execute): Same.
+
+        * data.c (Fsymbol_function): Name the argument `symbol' instead of
+        `sym', so make-docstring will list argument consistently with the
+        docstring.
+
+        * process.c (wait_reading_process_input): Make sure the screen
+        isn't garbaged (and therefore not displayed) before we enter the
+        select and start waiting for input.
+
+        * keyboard.c: #include <systime.h>.
+        * ymakefile (keyboard.o): This depends on systime.h.
+        * keyboard.c (input_available_clear_word): Replaced with
+        input_available_clear_time, which is a pointer to an EMACSTIME;
+        sometimes the time information is larger than a single word.
+        (read_char): Changed ..._word to ..._time.
+        (input_available_signal): Use the EMACS_SET_SECS_USECS macro to
+        clear *input_available_clear_time, instead of zapping a zero into
+        *input_available_clear_word.
+        (set_waiting_for_input, clear_waiting_for_input): Adjusted
+        appropriately.
+
+1992-05-10  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+        * editfns.c (make_buffer_string): New function.
+        * lisp.h (make_buffer_string): Declare it here.
+        * editfns.c (Fbuffer_substring): Call make_buffer_string instead
+        of writing it out.
+        (Fbuffer_string): Call make_buffer_string instead of make_string,
+        so we can deal with buffer relocations.
+        * minibuf.c (read_minibuf): Same here.
+
+1992-05-09  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+        * syssignal.h (sigunblock): New macro, taken from 18.58's
+        emacssignal.h file.
+        * sysdep.c (request_sigio): Use the sigunblock macro to enable
+        reciept of SIGWINCH, instead of the dysfunctional sigblockx.
+
+1992-05-08  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+        * search.c: Doc fix.
+
+1992-05-06  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+        * emacs.c (decode_env_path): If EVARNAME is zero, don't try to
+        call getenv on it.
+        * lread.c (init_lread): When we don't have an environment variable
+        to check, pass 0 instead of the empty string.
+
+        * alloc.c (Fmake_marker): Use `SIGMASKTYPE' instead of `int'.
+        Instead of calling sigsetmask twice - once to get the mask, and
+        again to restore it - call sigblock, specifying no additional
+        signals.
+
+1992-05-05  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+        * alloc.c: #include <syssignal.h>, for the sake of the
+        bug-catching code in Fmake_marker.
+        ymakefile: Add dependency.
+
+        * syssignal.h [not POSIX_SIGNALS] (SIGFULLMASK): New definition,
+        for symmetry with the "defined (POSIX_SIGNALS)" case.
+
+        * callproc.c (child_setup): Since we always get the environment
+        from Vprocess_environment, don't bother to take the environment
+        the subprocess should inherit as an argument anymore.
+        * process.c (create_process): Don't pass environment as a
+        variable.  Just preserve it across call to fork.
+
+1992-05-04  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+        * floatfns.c: #include <syssignal.h>.
+        (float_error): Use SIGEMPTYMASK instead of zero.
+        
+        * syssignal.h [POSIX_SIGNALS] (sigmask): Defined to expand to a
+        statement expression under GCC, or a function call otherwise.
+        (sigpause, sigblock, sigunblock, sigsetmask): These are now
+        K&R-compatible macros.
+        * systerm.h [POSIX_SIGNALS] (sys_sigmask): Here is the function
+        the POSIX version of sigmask calls when we're not compiling with
+        GCC.
+        * alloc.c (Fmake_marker): Undo changes of Apr 29.
+        * callproc.c (Fcall_process): Same.
+        * data.c (arith_error): Same.
+        * floatfns.c (float_error): Same.

+
+1992-04-29  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+        * x11term.h (CLASS): Change this from "emacs" to "Emacs"; class
+        names should always start with an upper-case letter.
+
+        * syssignal.h: Arranged cpp conditionals so that the specific
+        cases come first, generic cases last.
+
+        * syssignal.h (sigpause, sigblock, sigunblock, sigsetmask): Macros
+        removed; they require GCC, and Emacs 19 should compile without GCC.
+        (EMACS_SIGPAUSE, EMACS_SIGBLOCK, EMACS_SIGUNBLOCK,
+        EMACS_SIGSETMASK, EMACS_SIGFREE, EMACS_SIGHOLDX, EMACS_SIGBLOCKX,
+        EMACS_SIGUNBLOCKX, EMACS_SIGPAUSEX): These are new macros that
+        don't require GCC, but expand to statements.
+        * callproc.c (Fcall_process): Use new EMACS_SIG* macros from
+        syssignal.h.
+        * keyboard.c (gobble_input): Same.
+        * sysdep.c (request_sigio, unrequest_sigio): Same.
+        * x11term.h (BLOCK_INPUT, UNBLOCK_INPUT): Same.
+        * alloc.c (Fmake_marker): Same.
+        * data.c (arith_error): Same.
+        * floatfns.c (float_error): Same.
+
+1992-04-28  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+        * ymakefile: If we're using GCC version 2.0 or later, use "$(CC)
+        -nostdlib" as the linker.  This will allow us to find libgcc.a
+        even when GCC puts it in a really weird place.
+        (YMF_PASS_LDFLAGS): New macro.
+        (temacs): Use it.
+
+        * s/hpux.h: Doc fix.
+
+        * filelock.c (egetenv): Declare this.
+        (lock_path, SUPERLOCK_NAME, superlock_path): New variables and
+        macros.
+        (MAKE_LOCK_PATH, lock_file, unlock_file, lock_superlock): Use the
+        variables lock_path and superlock_path instead of the PATH_LOCK
+        and PATH_SUPERLOCK macros.
+        (init_filelock): New function.
+        * emacs.c (main): Call the init_filelock function.
+        * paths.h.in (PATH_SUPERLOCK): Removed.  This is now calculated
+        from PATH_LOCK or from the EMACSLOCKDIR environment variable.
+
+        * filelock.c (MAKE_LOCK_PATH): New macro.
+        (lock_file, unlock_file, Ffile_locked_p): Use it.
+
+        * syntax.c (Fmodify_syntax_entry): Note that '-' is a synonym for
+        ' ' (both denote whitespace), that '\\' denotes the escape class,
+        and that '/' denotes the character-quote class.  The description
+        used to claim that '\\' denoted the character-quote class, and
+        neglected to mention '-' and '/'.
+
+        * filelock.c (lock_file): Doc fix.
+
+1992-04-27  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+        * callproc.c (init_callproc): Get the default Vexec_path from the
+        environment variable "EMACSPATH"; get Vdata_directory from
+        "EMACSDATA".
+
+        * ymakefile: Fix #endif and #else comments.
+
+1992-04-27  Richard Stallman  (rms at mole.gnu.ai.mit.edu)
+
+        * ymakefile (xemacs): Link xemacs to temacs if HAVE_SHM.
+
+        * ymakefile (paths.h, config.h): Never copy, always fail.
+
+        * process.c (wait_reading_process_input): Redisplay if screen_garbaged.
+        Call do_pending_window_change first.
+        Include dispextern.h.
+        * ymakefile (process.o): Added dependency.
+
+        * ymakefile (OLDXMENU_OPTIONS): New macro, used compiling oldxmenu.
+
+1992-04-25  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+        * ymakefile: Changed all references to LD_CMD to LINKER, for
+        compatibility with the 18.58 configuration files.
+        * s/aix3-1.h, s/sunos4shr.h: Same here.
+
+        * ymakefile: Doc fixes.
+
+        * ymakefile (CC, MAKE): Set these variables from optional macros.
+        Change all uses of `make' to ${MAKE}.
+
+        * ymakefile: use HAVE_X11 as alias for X11.
+
+        * ymakefile (LIB_GCC, GNULIB_VAR): Handle GCC 2.
+
+        * process.c (allocate_pty): Re-arranged conditionals to put the
+        system-specific-case first, and the generic case in the #else
+        section, for consistency with the rest of Emacs.
+
+        * process.c (allocate_pty): Wait until we fail to open three ptys
+        in a row before concluding that we've reached the end of the ptys.
+
+1992-04-22  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+        * ralloc.c: #include "getpagesize.h".
+
+        * search.c (Flooking_at): Use search_regs.num_regs instead of
+        RE_NREGS.  As of regex version 0.4, the compiler allocates the
+        registers, and may allocate more than RE_NREGS.
+        (search_buffer): Same.
+        (Freplace_match): Use search_regs.num_regs to tell how many
+        registers are valid.  Also note that if none are valid, no search
+        has been performed.
+        (match_limit): Same.
+        (Fmatch_data): Same.
+        (Fstore_match_data): If we're trying to store more registers than
+        search_regs has allocated, re-allocate them to make room.
+
+1992-04-21  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+
+        * callproc.c (egetenv): Declare the type of VAR.
+
+        * lisp.h: Don't undefine NULL.  There is no longer any conflict.
+
+        * lisp.h (NUMBERP): New macro.
+        * editfns.c (Fformat): Protect the sections that deal with
+        Lisp_Float objects with a "#ifdef LISP_FLOAT_TYPE".
+        * bytecode.c (Fbyte_code): Use the NUMBERP macro instead of
+        explicitly checking for the Lisp_Float tag.
+        * callint.c (Fcall_interactively): Same here.
+
+        * xrdb.c (magic_searchpath_decoder): Re-allocate string as needed,
+        rather than making it a fixed-size array.
+
+        * xfns.c (Fx_rebind_key): Don't declare modifier_list to be a
+        register variable.  It's too big, and we need the address of its
+        first element when we pass it to XRebindKeysym anyway.
+
+        * fileio.c (Fdo_auto_save): Doc fix.
+
+1992-04-20  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+        * search.c (search_buffer): Cast RE_EXACTN_VALUE to char, because
+        the regex-0.4 distribution says so.
+
+        * ymakefile (dired.o): This depends on regex.h.
+
+        * process.c (wait_reading_process_input): There is code here which
+        sends SIGIO to Emacs if we thought we had input available but
+        didn't get SIGIO.  If the system doesn't have SIGIO, then
+        #ifdef it out.
+
+        * print.c (Fexternal_debugging_output): Arguments were declared
+        ANSI-style - rewritten in K&R 1 fashion.
+
+        * floatfns.c (IN_FLOAT): Cast the zero in the `else' clause of the
+        conditional expression to SIGTYPE, to match the type of the
+        float_error call in the `then' clause.
+
+        * s/hpux8: #define HPUX8; this is supposed to be customary
+        procedure, and fileio.c was expecting it, but somehow it didn't
+        get defined.
+
+        * sysdep.h: Move inclusions of [AIX] <sys/hft.h>,
+        <sys/devinfo.h>, <sys/pty.h>, <unistd.h> [NEED_BSDTTY]
+        <sys/bsdtty.h>, [HPUX and HAVE_PTYS] <sys/ptyio.h>, [SYSV_PTYS]
+        <sys/tty.h>, <sys/pty.h>, and [pfa] <sys/file.h> to systerm.h;
+        also move undefinition of LLITOUT under BSD4_1 to systerm.h.
+        * systerm.h: They're here.
+
+        * xterm.c (XTcursor_to, XTclear_end_of_line): Declare to return
+        int in the function definitions as well as their declarations.
+
+1992-04-19  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+        * fileio.c (directory_file_name): When checking if the string ends
+        with '/', check that slen is a valid length *before* examining
+        dst[slen-1], not after.
+
+1992-04-18  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+        * xterm.c (x_death_handler): New function.
+        (x_error_handler): Call x_death_handler to shut down Emacs.
+        (x_term_init): Use x_death_handler to handle SIGPIPE, instead of
+        x_error_handler, which expects to be passed a display and an
+        event.
+        * process.c (send_process): This used to set a handler to
+        catch SIGPIPEs when writing to a subprocess, and then set the
+        handler to SIGDFL after writing, but this would stomp on the
+        SIGPIPE handler for for the X connection.  So restore the prevous
+        handler instead of changing to SIGDFL.
+
+1992-04-18  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+        * indent.c (compute_motion): Fix skipping invis lines and
+        truncation at right margin.
+
+1992-04-17  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+        * s/hpux.h (PTY_NAME_SPRINTF, PTY_TTY_NAME_SPRINTF): Use pty_name,
+        not ptyname. 
+        * s/rtu.h: Same.
+
+        * process.c (pty_process): Add 'int' to the declaration 'static
+        pty_processes;'.  This makes it a happy declaration even when
+        static has been #defined as the empty string.
+        * xterm.c (XTcursor_to, XTclear_end_of_line): Same.
+
+        * unexec.c (sbrk): Declare this to return void * if __STDC__ is
+        defined, or char * otherwise.
+
+        * lread.c init_lread): Re-cleaned logic.  To determine whether the
+        load path was changed before dumping, cons up a dump path and
+        compare it.  This method is more localized and accurate.
+        (initial_path): Variable removed.
+        (syms_of_lread): Don't staticpro.
+
+        * floatfns.c (float_error): Declare and define this to return
+        SIGTYPE.
+
+        * systime.h [HAVE_TIMEVAL] (EMACS_GET_TIME): Declare dummy to be a
+        real struct timezone, instead of an EMACS_TIME.  Since
+        HAVE_TIMEVAL is defined, struct timezone ought to be declared, so
+        there's no harm in passing the genuine article.
+
+        * sysdep.c [USG] (rename): Place under the protection of a new
+        preprocessor symbol, HAVE_RENAME.
+        * s/hpux.h (HAVE_RENAME): Defined.
+
+        * sysdep.c [USG] (setpriority): Declare to return int, not void.
+
+        * s/template.h: Add template section for HAVE_TERMIOS.
+
+        * term.c (cursor_to, raw_cursor_to, fatal): Do declare the types
+        of the arguments.
+
+1992-04-15  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+        * callint.c (Fcall_interactively): When the interactive spec is
+        a string, it may be relocated while reading the arguments.  To
+        avoid this, make a copy of the spec to refer to, instead of
+        using a pointer to the data of the spec string.
+
+        * callint.c (Fcall_interactively): When following the function
+        chain of a symbol, check for quits.
+
+1992-04-13  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+        * lread.c (init_lread): Make the load path default to
+        PATH_LOADSEARCH when we're not dumping (null purify-flag), and
+        PATH_DUMPLOADSEARCH when we are (not (null (purify-flag))).
+        Change from April 7th incorrectly always used PATH_DUMPLOADSEARCH.
+
+        * lread.c (init_lread): Cleaned up logic; to determine whether the
+        load path was changed before dumping, remember the initial value
+        and compare against it.
+        (initial_path): New variable to support this.
+        (syms_of_lread): staticpro initial_path.
+
+        * ymakefile: Renamed filenames like "*-dist" to "*.in".
+
+        * config.h.in: Doc fixes.
+
+1992-04-11  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+        * config.h-dist: Renamed to config.h.in, for consistency with
+        the installation conventions of other GNU programs.
+        * paths.h-dist: Renamed to paths.h.in.
+
+1992-04-11  David J. MacKenzie  (djm@wookumz.gnu.ai.mit.edu)
+
+        * termcap.c: Declare getenv.
+
+1992-04-08  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+        * Makefile: Renamed to Makefile.in; the configure script will edit
+        this to produce Makefile.
+
+1992-04-07  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+        * paths.h-dist (PATH_DUMPLOADSEARCH): New macro.
+        * lread.c (init_lread): If we're building an Emacs to be dumped,
+        use PATH_DUMPLOADSEARCH as the default load path, so we can
+        correctly find our lisp files.
+
+        * config.h-dist, paths.h-dist: Added "-*- C -*-" to top lines, so
+        Emacs will know that these are really C source.
+
+1992-04-03  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+        * search.c (syms_of_search): When allocating memory
+        searchbuf.buffer, cast the return value of malloc to unsigned char
+        *, not char *; this changed in the most recent version of the
+        regex code.
+
+1992-03-31  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+        * doc.c (Fdocumentation): Don't forget to end each line of the
+        docstring with "\n\".
+
+        * process.c (Fprocess_connection): Change "#ifdef 0" around this
+        function to "#if 0".
+
+        * eval.c (Flet, FletX): Signal an error if one of the let's binding
+        clauses has more than one value form, as in (let ((a 1 2)) a).
+
+        * eval.c (Ffuncall): Re-install change of March 10; I don't know
+        why it went away.
+
+        * search.c (compile_pattern): Declare the variable which holds the
+        return value of re_compile_pattern to be const, if this is ANSI C.
+
+        * alloc.c (xrealloc): Change "ese" to "else".
+
+        * crt0.c (start1) [sun_soft]: Change 'jst' to 'jsr'.  The Sun
+        assembly language manual doesn't list any 'jst' instruction, I
+        don't know of one personally, and all the analogous code
+        around it uses 'jsr'.
+
+        * crt0.c [m68k]: Merged with GNU C Library's version: added
+        conditionals for sun_68881, sun_fpa, sun_soft.
+
+        * config.h-dist: Adjusted for renaming of share-lib to etc.
+        * lread.c (read1): Same.
+        * doc.c (Fdocumentation_property, Fsnarf_documentation): Same.
+        * ymakefile: Same.
+
+1992-03-30  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+        * crt0.c: Merged changes from 18.58:
+        [hp9000s300]: Set flag_fpa.  Define float_loc.
+        [new hp assembler]: Double flag_fpa and flag_68881 if %d2!=0.
+        (start1): Declare to be static at the top of the file.
+        (_start): Removed static declaration in this function; since
+        everyone wants it, we'll just put it here.
+
+1992-03-20  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+        * fileio.c (Finsert_file_contents): Allow quitting from I/O.
+        (Fcopy_file): Likewise.
+
+1992-03-20  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+        * m-intel386.h (HAVE_ALLOCA): Inhibit if C_ALLOCA.
+        (LIB_STANDARD): Alternate USG value if __GNUC__ or C_ALLOCA
+
+        * alloc.c (xrealloc): If handed a NULL pointer for the block to
+        resize, malloc a new block and return that.  Not all reallocs do
+        this.
+
+        * m/elxsi.h: Doc fix.
+
+1992-03-18  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+        * dispnew.c (Fsleep_for): Call wait_reading_process_input, whether
+        or not we have process support; let the emulator do the work.
+        * emacs.c (fatal_error_signal, Fkill_emacs): Call
+        kill_buffer_processes even when subprocesses is not #defined; we
+        have a stub.
+
+        * process.c [not defined (subprocesses)] (Fget_buffer_process,
+        init_process, syms_of_process): New stub versions of these functions.
+        * emacs.c (main): Call init_process and syms_of_process whether or
+        not subprocesses is #defined.
+        * xdisp.c (decode_mode_spec): Call Fget_buffer_process whether or
+        not subprocesses is #defined.
+
+1992-03-17  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+        * keyboard.c (kbd_buffer_get_event): Call
+        wait_reading_process_input, even when subprocesses is not
+        #defined, instead of doing a whole lot of hairy SIGIO-pausing
+        stuff.
+        * dispnew.c (Fsit_for): Call wait_reading_process_input, whether
+        or not subprocesses is #defined.
+
+        * process.c (wait_reading_process_input): Since we're no longer
+        checking for exceptional conditions in the call to select, all of
+        the different ways to call select for different systems have
+        become the same; remove the #if conditionals around this.
+
+        * keyboard.c (read_char): When returning quit_char because we got
+        an interrupt signal, claim that the character came from the
+        currently selected screen.
+
+1992-03-16  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+        * callproc.c (Fcall_process): Doc fix.
+
+        * process.c [not defined (subprocesses)] (kill_buffer_processes):
+        New dummy version of this function.
+        * buffer.c (Fkill_buffer): Removed '#ifdef subprocesses'
+        protection from the call to kill_buffer_processes; this is safe
+        whether or not we actually have subprocesses.
+
+1992-03-14  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+        * m/pfa50.h: New file.
+        * process.c (create_process, process_send_signal): Added changes
+        for m/pfa50.h.
+        * sysdep.c: same.

+
+1992-03-14  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+        * callproc.c (child_setup): Always put the child in its own
+        process group.
+
+1992-03-13  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+        * mem_limits.h (POINTER): Doc fix.
+
+        * ralloc.c: Don't #include lisp.h and xterm.h; we no longer need
+        to block input in critical sections.
+        (r_alloc, r_alloc_free, r_re_alloc): Don't use BLOCK_INPUT and
+        UNBLOCK_INPUT; these are no longer needed.
+        (struct bp): Doc fix.
+
+1992-03-11  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+        * ralloc.c (obtain): When deciding how many pages to request, take
+        into account the amount of spare bytes at the end of the current
+        page; let get be ROUNDUP (size - already_available), instead of
+        ROUNDUP (size).
+        (relinquish): Re-organized for clarity.
+
+        * editfns.c (Fcurrent_time): Updated to return the current time's
+        seconds split into two 16-bit integers (similar to the system used
+        by file-attributes), and the milliseconds.
+
+1992-03-10  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+        * process.c (Faccept_process_output): Add new optional argument
+        TIMEOUT-MSECS, and return non-nil iff we actually got some input
+        from the process(es).
+        (wait_reading_process_input): Make return value indicate whether
+        we got some input from the specified process, when read_kbd is a
+        process, or from any process when read_kbd isn't particular.
+
+        * indent.c (Fmove_to_column): Pass the correct number of arguments
+        to Findent_to.
+
+        * eval.c (Ffuncall): If a subr is asking for too many arguments,
+        abort instead of printing an error message; this is an internal
+        flaw in Emacs, and the subr cannot be called.
+
+1992-03-06  Roland McGrath  (roland@geech.gnu.ai.mit.edu)
+
+        * doc.c (Fdocumentation, Fdocumentation_property): Take optional
+        new arg to not pass results thru substitute-command-keys.
+
+1992-03-05  Jim Blandy  (jimb at pogo.cs.oberlin.edu)
+
+        * unexmips.c (unexec): When setting up the data_section header,
+        calculate the size of the section as "brk - data_start," not "brk
+        - DATA_START".
+
+1992-02-23  Jim Blandy  (jimb at pogo.cs.oberlin.edu)
+
+        * fileio.c: #include "systime.h".
+        (Fcopy_file): Use the systime.h macros to copy the time to the new
+        file.
+        * ymakefile: Note that fileio.o depends on systime.h.
+
+        * ymakefile (dispnew.o): Note that this depends on systerm.h and
+        systime.h.
+        (editfns.o, xterm.o, sysdep.o): Note that this depends on
+        systime.h.
+        (emacs.o, keyboard.o, process.o, sysdep.o): Note that these depend
+        on systerm.h.
+
+        * systerm.h: Expanded to handle getting and setting terminal
+        parameters:
+        (struct emacs_tty): New structure, which consolidates all of the
+        old tty parameter structures.
+        (EMACS_GET_TTY, EMACS_SET_TTY, EMACS_TTY_TABS_OK): New macros.
+        * sysdep.c (TABS_OK): Definitions of this macro removed;
+        EMACS_TTY_TABS_OK replaces it.
+        (TERMINAL): Definitions removed; now we use struct emacs_tty.
+        [VMS] (input_chan): Renamed to...
+        (input_fd): and defined even when VMS isn't; in that case, we
+        leave it initialized to zero, which is the input tty.  This allows
+        us to use the EMACS_GET_TTY and EMACS_SET_TTY for both VMS and
+        Unix.
+        (discard_tty_input): Use struct emacs_tty and its macros instead
+        of TERMINAL.  Replace some of conditional with a call to
+        EMACS_GET_TTY.
+        (child_setup_tty): Use struct emacs_tty and its macros instead of
+        TERMINAL and conditionals.
+        (old_gtty, old_ltchars, old_tchars, old_lmode): Replaced by...
+        (old_tty): New variable.
+        (lmode): Made conditional on BSD4_1, since it's only used by the
+        BSD4_1 support code now.
+        (init_sys_modes): Define tty to be a struct emacs_tty, not a
+        TERMINAL.  Use macros to get and set parameters for VMS and
+        Unices. Set lmode, tchars, and ltchars along with the rest of the
+        tty state.
+        (tabs_safe_p): Use EMACS_GET_TTY and EMACS_TTY_TABS_OK instead of
+        conditionals.
+        (reset_sys_modes): Use EMACS_SET_TTY to restore the settings from
+        old_tty, instead of using hairy conditionals.
+
+        * sysdep.c (get_screen_size): Neatened; now each system of
+        reporting the screen size is separated from the rest.
+        
+        * systerm.h (EMACS_HAVE_TTY_PGRP, EMACS_GET_TTY_PGRP,
+        EMACS_GET_TTY_PGRP): New macros to handle setting a tty's current
+        process group.
+        * sysdep.c (setpgrp_of_tty): Use the above, instead of
+        conditionals.
+
+        * sysdep.c: #include "systerm.h".
+        #ifs that choose #include files moved from here...
+        * systerm.h: to here.
+
+        * sysdep.c [APOLLO]: We now undefine TIOCSTART not here but...
+        * systerm.h: here.
+
+        * sysdep.c [BROKEN_TIOCGETC]: We now undefine TIOCGETC not here but...
+        * systerm.h: here.
+
+        * sysdep.c [BROKEN_FIONREAD]: We now undefine FIONREAD and FASYNC
+        not here but...
+        * systerm.h: here.
+
+        * process.c (process_send_signal): Steal 18.58's version of this,
+        but incorporate the support for VMS signals.
+            
+        * syssignal.h (EMACS_KILLPG): New macro.
+        * process.c (process_send_signal): Use it.
+        * sysdep.c (sys_suspend): Use it.
+
+        * syssignal.h (SIGCHLD): If we have SIGCLD and not SIGCHLD, define
+        SIGCHLD as an alias for SIGCLD.
+        * sysdep.c: Remove code for above.
+
+        * sysdep.c (init_baud_rate): Rather than trying to maintain the
+        illusion of an abstraction with the OSPEED and SETOSPEED macros,
+        just use conditionalized code for each terminal kind.  This is the
+        only place we ever need this functionality.
+        (OSPEED, SETOSPEED): Definitions removed.
+
+1992-02-22  Jim Blandy  (jimb at pogo.cs.oberlin.edu)
+
+        * sysdep.c: Moved definition of sigunblock macro to ...
+        * syssignal.h: Here.
+
+        * hftctl.c: #include <sys/uio.h> before #including <sys/tty.h>.
+        (hfqry, hfskbd): Declare these functions as static before all uses.
+        * unexaix.c (make_hdr, mark_x, copy_text_and_data, copy_sym):
+        Declare as static before all uses.
+        Remove extraneous semicolons from #ifdefs of COFF and XCOFF
+        (unrelocate_symbols): cast the initializers of t_start and d_start
+        to ulong.
+
+        * s/template.h: Include a clause for the HAVE_TERMIO flag.
+
+1992-02-21  Jim Blandy  (jimb at pogo.cs.oberlin.edu)
+
+        * keyboard.c (read_char): Don't clear Vquit_flag when we catch an
+        interrupt and return a quit_char; this change (Mar 21 1991) is too
+        large a change in functionality for the cleanliness it gains.
+
+        * pwd.h: Renamed to vms-pwd.h, so that we don't get it by accident
+        when we #include <pwd.h> with the `-I.' flag given to the
+        compiler.
+        * editfns.c [VMS]: Changed to include vms-pwd.h instead of pwd.h.
+        * fileio.c [VMS]: Same.
+        * filelock.c [VMS]: Same.
+        * sysdep.c [VMS]: Same.
+
+        * xrdb.c: Changed to #include "vms-pwd.h" if VMS is defined,
+        instead of including <pwd.h> unconditionally.
+
+        * window.c (Fset_window_display_table): Rearranged to make etags
+        happy.
+
+        * xterm.c (XTread_socket): Clear the meta flag from the keypress
+        event before handing it to XLookupString.
+
+1992-02-20  Jim Blandy  (jimb at pogo.cs.oberlin.edu)
+
+        * sysdep.c: No need to test #ifdef TIOCGETP before #undefing it.
+
+1992-02-19  Jim Blandy  (jimb at pogo.cs.oberlin.edu)
+
+        * systime.h: New file.
+        * dispnew.c: #include "systime.h" to get <time.h> or <sys/time.h>,
+        whichever is appropriate, instead of using a conditional.
+        (Fsleep_for, Fsit_for, Fsleep_for_millisecs): Use the systime.h
+        macros instead of HAVE_TIMEVAL conditionals.
+        * editfns.c: #include "systime.h" to get <time.h> or <sys/time.h>,
+        whichever is appropriate, instead of using a conditional.
+        * fileio.c: Same.
+        * process.c: Same.
+        * xterm.c: Same.
+        (wait_reading_process_input): Use the systime.h macros.
+        * sysdep.c: #include "systime.h" to get <time.h> or <sys/time.h>,
+        whichever is appropriate, instead of using a conditional.
+
+        * m/template.h: Add description of NO_SOCK_SIGIO.
+
+        * sysdep.c (reset_sys_modes): Doc fix.
+
+        * keyboard.c (sigfree, sigholdx, sigblockx, sigunblockx,
+        sigpausex): Definitions moved to syssignal.h.
+
+        * dispnew.c: Doc fix.
+
+        * systerm.h: New file, to consolidate the system-dependent
+        terminal-handling trash.
+        * emacs.c: #include systerm.h.
+        (main): Use systerm.h macros instead of conditionals.
+        * dispnew.c: #include systerm.h.
+        (update_screen): Use EMACS_OUTQSIZE instead of the direct ioctl.
+        * keyboard.c: #include systerm.h to get the proper FIONREAD header
+        files, instead of using conditional.
+
+        * syssignal.h: Added copyright notice.
+
+        * emacssignal.h: Renamed to syssignal.h, to be like sysdep.c.
+        * data.c, keyboard.c, process.c, sysdep.c, ymakefile: Changed
+        #include directives.
+
+1992-02-15  Jim Blandy  (jimb at pogo.cs.oberlin.edu)
+
+        * m/intel386.h: Don't bother casting the argument to the signal
+        function; the SIGTYPE code in config.emacs ought to take care of
+        this.
+
+        * buffer.c (record_buffer): Doc fix.
+
+1992-02-13  Jim Blandy  (jimb at pogo.cs.oberlin.edu)
+
+        * s/iris3-6.h: #define HAVE_GETWD.
+
+1992-02-11  Jim Blandy  (jimb at pogo.cs.oberlin.edu)
+
+        * window.c (Fwindow_at): Accept position as two arguments, not a
+        cons of numbers.
+
+        * window.c (scroll_command): Undo the Jan 31 change; do set the
+        current buffer to the selected window's buffer.  A simple
+        set-buffer will make these two different.
+
+1992-02-10  Jim Blandy  (jimb at pogo.cs.oberlin.edu)
+
+        * callproc.c (Fcall_process): Clear synch_process_death and
+        synch_process_retcode to zero before forking the process.
+
+        * process.c (synch_process_death, synch_process_retcode): Don't
+        declare them extern here.
+        * process.h (synch_process_death, synch_process_retcode): Declare
+        them extern here, along with synch_process_alive.
+
+        * s/hpux.h: Define CLASH_DETECTION.
+
+        * window.c (init_window_once): Don't pass any arguments to
+        make_window.
+
+        * keyboard.c (command_loop_1): Move the label directly_done out of
+        the else block to just after the else block.  This shouldn't
+        change the semantics of the code, but appears to avoid a compiler
+        bug on SCO Unix V.3.2v2.
+
+        * fileio.c (Fset_umask, Fumask): New functions.
+        (syms_of_fileio): defsubr them.
+
+        * undo.c (Fprimitive_undo): When undoing a deletion with the point
+        before the deleted text, use Finsert_before_markers so that the
+        mark will end up on the other side of the text, if it's in the
+        area at all.
+
+        * xdisp.c (redisplay): Properly compute TAB_OFFSET for compute_motion.
+
+        * keyboard.c (command_loop_1): Don't check whether cursor is at
+        edge of screen here.
+        * dispnew.c (direct_output_forward_char): Check here, and return
+        zero if it can't be done.  And compare the cursor position to the
+        window boundaries, not the screen boundaries.
+
+1992-02-05  Jim Blandy  (jimb at pogo.cs.oberlin.edu)
+
+        * screen.c (Fscreen_parameters): If the screen has a minibuffer
+        window on another screen, return the window, instead of nil.
+        (store_screen_param): If the value of the minibuffer parameter is
+        a window, try to make it the surrogate minibuffer window.
+        (Qminibuffer): New variable, to support above change.
+        (syms_of_screen): initialize and staticpro it.
+
+        * m/tad68k.h: New file.
+
+        * fileio.c (Ffile_accessible_directory_p): New function.
+        (syms_of_fileio): defsubr it.
+        * callproc.c: #include <errno.h>.
+        (child_setup):  Accept yet another argument, current_dir.
+        Don't try to report an error here if current_dir is inaccessible;
+        this function is called in a vforking process.  Just have the
+        process exit with an error code.
+        (Fcall_process): Make sure that the current directory is okay
+        here, before we fork.  Pass the current_dir argument.
+        * process.c (create_process): Same here.
+
+        * callproc.c (Fcall_process): Don't assign into args[1] when nargs
+        < 2.  Instead, use a new variable called infile.  Re-arranged
+        logic which processes the BUFFER argument.
+
+1992-02-03  Jim Blandy  (jimb at pogo.cs.oberlin.edu)
+
+        * fileio.c (Fexpand_file_name): Doc fix.
+
+        * scroll.c (line_ins_del): Since we're calculating the array from
+        end to beginning, make the indices go that way, and thus clearly
+        get the right boundary.  This used to ignore the [0] element, and
+        write in the [screen_height] element, which doesn't exist.
+
+1992-02-03  Richard Stallman  (rms at mole.ai.mit.edu)
+
+        * xdisp.c (redisplay, try_window_id): Special case for change
+        at beginning of line, if using selective display.
+
+1992-01-31  Jim Blandy  (jimb at pogo.cs.oberlin.edu)
+
+        * m/delta88k.h: Added USUAL-OPSYS information, for the
+        config.emacs script to use.
+
+        * window.c (scroll_command): Don't bother setting the current
+        buffer to the selected window's buffer; this should always already
+        be the case.  Add check just in case.
+
+        * indent.c (compute_motion): Don't pack vpos and hpos into one int;
+        use separate variables hpos/vpos and prev_hpos/prev_vpos.
+        (vmotion): Use largest int as tovpos arg to compute_motion.
+
+1992-01-30  Jim Blandy  (jimb at pogo.cs.oberlin.edu)
+
+        * window.c: #include "keyboard.h" to get the Qmode_line and
+        Qvertical_split declarations.
+        * ymakefile (window.o): Note that this depends on keyboard.h.
+
+        * callproc.c (getenv_internal): Cast the pointer to the variable's
+        value to a char *; elisp strings are unsigned char *'s.  And
+        valuelen is an int *, not an int **.
+
+        * scroll.c (do_scrolling): Document meaning of enable flag in
+        temp_screen.
+
+1992-01-30  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+        * m-orion105.h (C_DEBUG_SWITCH, LIBS_DEBUG): Defs deleted.
+
+1992-01-29  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

+        * m-iris4d.h (C_SWITCH_MACHINE): New definition.
+
+1992-01-28  Jim Blandy  (jimb at pogo.cs.oberlin.edu)

+        * term.c: #include "keyboard.h", for Vfunction_key_map.
+        * keyboard.h: Declare Vfunction_key_map.
+
+        * keyboard.h: New file, for external declarations used in
+        processing keyboard input and events.
+        * lisp.h (Qmode_line, Qvertical_split, num_input_chars,
+        poll_suppress_count): Extern declarations moved to keyboard.h.
+        * keyboard.c: #include "keyboard.h".
+        (Qvscrollbar_par, Qvslider_part, Qvthumbup_part,
+        Qvthumbdown_part, Qhscrollbar_part, Qhslider_part,
+        Qhthumbleft_part, Qhthumbright_part): Moved declarations here from
+        xfns.c, so they're with the other event heading symbols.
+        * eval.c: #include "keyboard.h".
+        * ymakefile (callint.o, keyboard.o, keymap.o, xfns.o, eval.o):
+        Note that these depend on keyboard.h.
+
+        * xfns.c: The above symbols aren't here any more.  #include
+        "keyboard.h" to get them.
+        (syms_of_xfns): Don't initialize or staticpro them.
+        * keyboard.h: Added extern declarations for the above.
+        * callint.c: #include "keyboard.h".
+
+        * xfns.c (Vmouse_screen_part): Variable removed, no longer used.
+        (syms_of_xfns): Changed accordingly.
+
+        * xterm.c (Qmouse_moved): Variable removed, no longer used.
+        (Qmouse_click, Qscrollbar_click): Removed.  These are now event
+        types, in keyboard.c and keyboard.h; they're no longer used in
+        this way.
+        (Vmouse_window, Vmouse_screen_part): Extern declarations removed.
+        (XTread_socket): Don't assign to Vmouse_window or
+        Vmouse_screen_part.
+        (syms_of_xterm): Changed accordingly.
+
+        * keyboard.h (EVENT_HAS_PARAMETERS, EVENT_HEAD, EVENT_WINDOW,
+        EVENT_BUFFER_POSN, EVENT_SCROLLBAR_BUTTON, EVENT_WINDOW_POSN,
+        EVENT_TIMESTAMP, EVENT_HEAD_UNMODIFIED, EVENT_HEAD_KIND): New
+        macros to recognize and access events that have parameters, like
+        mouse events.
+        * keyboard.c (read_char, echo_char, Fmouse_click_p,
+        read_key_sequence): Use them.
+        * keymap.c: #include "keyboard.h".
+        (access_keymap, store_in_keymap, Fsingle_key_description): Use the
+        macros from keyboard.h.
+
+        * keyboard.c (Qevent_kind): New symbol, naming the property of an event
+        header where we put the event's type.
+        (Qfunction_key, Qmouse_click, Qscrollbar_click): New symbols, used
+        to tag different kinds of events.
+        (Qevent_unmodified): New symbol, naming the property
+        of an event header where we put an unmodified version of the event
+        header.
+        (modify_event_symbol): Take a new argument, SYMBOL_KIND, whose
+        value should be put on the Qevent_kind property of each symbol we
+        make.  Set the Qevent_unmodified property of each symbol we make.
+        (make_lispy_event): Pass the appropriate SYMBOL_KIND argument to
+        modify_event_symbol.
+        (struct event_head, head_table): New tables, to simplify the
+        initialization of some of the event heads.
+        (syms_of_keyboard): Initialize and staticpro the symbols given in
+        head_table, and put the Qevent_kind and Qevent_unmodified
+        properties on them.  Initialize all of the new symbols listed
+        above.
+
+        * keyboard.c (lispy_function_keys, lispy_mouse_names): Renamed
+        these from function_key_names and mouse_names, and moved them
+        outside of make_lispy_event, since static doesn't work on all
+        systems, and these can't be automatic.
+
+1992-01-28  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+        * fileio.c (Fwrite_region): Remove Alliant conditional.

+        * lisp.h (find_symbol_value): Declare it.
+        * keymap.c (current_minor_maps): Use it, instead of a call to
+        Fboundp and Fsymbol_value per every minor map, for every key
+        sequence read.
+
+        * xterm.c (x_make_screen_visible): Don't raise the window.  This
+        causes the window to pop to the front every time a message
+        appears, which isn't desirable.
+
+        * screen.c (Fselect_screen, Fdelete_screen, Fset_mouse_position,

+
+        * keyboard.c (read_key_sequence): When expanding a function key

+        keymap.c; this declaration made extern.
+        (syms_of_keyboard): DEFVAR and initialization of Vfunction_key_map

+        (kbd_buffer_store_event): Include a forward declaration for

+        * sysdep.c (struct save_signal): Say the handler returns SIGTYPE

+        (process_send_signal): If we have termios, use tcgetpgrp to get
+        the terminal's process group.  Have gid default to the child's
+        pid, to simplify the logic below.
+        * sysdep.c (flush_pending_output): If we are using termios, make
+        this function a no-op; since we're not in the tty's pgroup, we

+        and config.h.
+        Note that vm-limit.o depends on mem_limits.h.
+
+        * lread.c (read_escape): Return \a as '\007', not '\a'; the latter
+        isn't portable, and this routine would have to be revised anyway
+        to deal with anything other than ASCII.
+
+        * keymap.c (current_minor_maps): Rewritten not to use
+        function-local static variables, to accomodate DGUX.
+
+        * xterm.h (UNBLOCK_INPUT): Replace "abort ()" with "(abort (),
+        0)", to avoid type conflicts on odd systems like Ultrix.
+
+        * xrdb.c: Include <sys/types.h>, and declare getuid to return uid_t.
+
+        * xdisp.c (redisplay_window): Use SET_PT macro instead of

+        insdel.c (insert_from_string): Same.

+
+        * lisp.h (NULL): Renamed to NILP, so as not to conflict with
+        <stdio.h>, and <stddef.h>.  All callers changed; all
+        #undefinitions of NULL removed.
+
+1992-01-12  Jim Blandy  (jimb at pogo.cs.oberlin.edu)

+        arbitrary number of keymaps at a time.
+
+        * keyboard.c (Fread_key_sequence): GCPRO keybuf, since it can hold

+        (command_loop_1): Don't pass too many arguments to read_key_sequence.
+
+        * keyboard.c (add_command_key): New function; there are several

+
+        * ymakefile (CFLAGS): Don't automatically include C_DEBUG_SWITCH
+        in the value for CFLAGS; the configuration script will take care
+        of choosing the debugging and optimization switches.
+
+        * config.h-dist: Copy the GLYPH definitions from config.h to here.

+        directory containing architecture-independent data files.
+        (init_callproc): Initialize Vdata_directory from PATH_DATA, and

+        it for both Vexec_directory and Vdata_directory.
+        (syms_of_callproc): Doc fix for Vexec_directory, new DEFVAR_LISP
+        for Vdata_directory.

+        argument helps implement the behavior of Fnext_window.
+        (Fnext_screen): Document the new behavior.
+
+        * screen.c (make_minibuffer_screen): Do set has_minibuffer for
+        minibuffer-only screens.
+        (Fscreen_parameters): Correctly generate value of minibuffer
+        parameter using SCREEN_HAS_MINIBUF and SCREEN_MINIBUF_ONLY_P.
+        * screen.h (SCREEN_HAS_MINIBUF): New predicate.
+        * dispnew.c (change_screen_size): Use it.
+        * screen.c (Fdelete_screen): Use it.
+
+        * screen.c (Vglobal_minibuffer_screen): Renamed
+        Vdefault_minibuffer_screen to better describe its significance.
+        (make_screen_without_minibuffer, syms_of_screen): Adjusted.
+        * xfns.c (Fx_create_screen): Doc string adjusted.
+
+        * xdisp.c (display_mode_line): Make the code which names the
+        screen after the current buffer not depend on
+        Vglobal_minibuffer_screen.
+        * xterm.c (Vglobal_minibuffer_screen): Don't declare this extern
+        here; it's never used.
+
+1991-11-05  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)
+
+        * screen.c (Fdelete_screen): Document the fact that surrogate
+        minibuffer screens may not be deleted.
+
+        * screen.h (SCREEN_MINIBUF_ONLY_P): New predicate, true iff the
+        screen's only window is a minibuffer, aka a "minibuffer screen" or
+        a "minibuffer-only" screen.
+        * dispnew.c (change_screen_size): Use it.
+        * screen.c (Fselect_screen, next_screen, prev_screen,
+        Fdelete_screen): Use it.
+        * window.c (Fdisplay_buffer): Use it.
+
+        * screen.c (next_screen, prev_screen): Make MINIBUF a lisp
+        boolean, not a C boolean.
+        (Fnext_screen, Fdelete_screen): Changed to fit.
+        * window.c (Fnext_window, Fprevious_window): Changed to fit.
+
+        * screen.c (make_screen_without_minibuffer): Error string improvement.
+
+        * screen.c (syms_of_screen): Doc grammar fix for Vemacs_iconified.
+
+        * screen.c (next_screen): Added some sanity checks, rewrote comments.
+
+        * screen.h (Vglobal_minibuffer_screen): Don't declare this.  It
+        shouldn't be used for anything but screen creation.
+        * window.c (Fminibuffer_window): Vglobal_minibuffer_screen is not
+        necessarily the screen containing the current minibuffer window.
+        Also, call choose_minibuf_window; it does much of the work here.
+        (Fnext_window): Used to insist on looping through all screens if
+        Vglobal_minibuffer_screen was non-nil.  Now includes screen's
+        minibuffer window according to MINIBUF, no matter what screen it's
+        on, and ignores Vglobal_minibuffer_screen.  Loop termination logic
+        cleaned up.  Clarified doc string.
+        (Fprev_window): Same problems as Fnext_window, above.
+        * screen.c (Vglobal_minibuffer_screen): Documentation rewritten to
+        emphasize that it is only a parameter of the creation of
+        minibufferless screens, and not an indication of where the
+        minibuffer is.
+        (prev_screen): Used to assume that Vglobal_minibuffer_screen was
+        the only minibuffer-only screen, and would enter an infinite loop
+        if Vglobal_minibuffer_screen was the only screen in the list.
+        Rewritten to fix these problems.
+        * minibuf.c (Vglobal_minibuffer_screen): Don't declare it extern
+        here; it's not used.
+
+        * editfns.c (Fmessage): Don't call Fmake_screen_visible here.
+        * xdisp.c (message, message1): Call it here, so that Emacs C
+        functions like Fy_or_n_p make the screen visible too.
+
+1991-11-04  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)
+
+        * keyboard.c (readable_events): If EVENT_QUEUES_EMPTY, we can
+        short-circuit and say no.  Otherwise, if do_mouse_tracking, we can
+        short-circuit and say yes.  These things let us scan the event
+        queue less often.
+
+        * termhooks.h (mouse_tracking_enable_hook): Replaced by...
+        (mouse_moved, mouse_position_hook): It turns out that it is
+        possible and no less efficient simply to tell Emacs if the mouse
+        has moved since last noticed, and let it ask for the current mouse
+        position; X's pointer motion hints are a cool thing.
+        * term.c (mouse_tracking_enable_hook): Replaced by...
+        (mouse_position_hook): New, simpler interface.
+        * keyboard.c (struct movement, movement_buf, movement_ptr):
+        Replaced by...
+        (mouse_moved): This flag, to be used in conjuction with
+        mouse_position_hook.
+        (EVENT_QUEUES_EMPTY): Adjusted to use mouse_moved instead of
+        movement_buf and movement_ptr.
+        (tracking_off, Ftrack_mouse): Don't call mouse_tracking_enable
+        hook.
+        (note_mouse_position): Moved to xterm.c.
+        (get_mouse_position): Replaced by mouse_position_hook.
+        (make_lispy_event): Movement event generation code moved out to a
+        separate function...
+        (make_lispy_movement): Create a mouse movement event for the
+        current mouse position.  Use mouse_position_hook instead of
+        get_mouse_position.  Added static declaration for this above...
+        (kbd_buffer_get_event): Use mouse_moved instead of movement_buf
+        and movement_ptr.  Call make_lispy_movement instead of
+        make_lispy_event.
+        (init_keyboard): Initialize do_mouse_tracking.  Don't init
+        movement_ptr and movement_buf.
+        * xterm.h (STANDARD_EVENT_SET): Add PointerMotionMask and
+        PointerMotionHintMask to the set.
+        * xterm.c (pixel_to_glyph_translation): Renamed to
+        pixel_to_glyph_coords, made static, simplified to take advantage
+        of constant-size characters, and extended to return the bounding
+        rectangle of the glyph returned.
+        (construct_mouse_click): The 'button' field of a button event is
+        the button number, not a mask; convert it to a mask before
+        frobbing x_mouse_grabbed.  Call pixel_to_glyph_coords properly.
+        (last_mouse_screen, last_mouse_glyph): New variables, to keep
+        track of when the pointer has moved to a different glyph.
+        (note_mouse_position): Moved here from keyboard.c and made static.
+        Check if the new mouse position is over a new glyph.  If it is,
+        set mouse_moved flag; otherwise, call XQueryPointer to get the
+        next motion event.
+        (XTmouse_tracking_enable): No longer needed, since pointer motion
+        hints let us implement the simpler mouse position hook.
+        (XTmouse_position): New hook.  Call XQueryPointer to get the
+        current mouse position and request notification about the next
+        mouse movement.  Clear the mouse_moved flag.
+        (pixel_to_glyph_coords, construct_mouse_click,
+        note_mouse_position, XTmouse_position): Put these all on the same
+        page.
+        (XTread_socket): case MotionNotify, call note_mouse_position with
+        the right args; don't call pixel_to_glyph_translation.
+        (x_term_init): Set mouse_position_hook instead of
+        mouse_tracking_enable_hook.
+
+1991-10-31  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)
+
+        * xdisp.c (redisplay_window): When trying to avoid starting
+        display at the end of the buffer: check that startp < ZV, not
+        startp <= ZV.
+
+1991-10-29  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)
+
+        * xterm.c (x_do_pending_expose, XTmouse_tracking_enable): Use
+        SCREEN_IS_X instead of testing output_method directly.
+
+1991-10-26  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)
+
+        * xdisp.c (redisplay): In the single-screen optimization, always
+        update the minibuffer's screen as well as the selected screen, no
+        matter what the echo_area_glyphs are.  This makes sure that
+        messages get cleared after a keystroke.
+
+1991-10-25  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)
+
+        * callint.c (Finteractive): Doc fix.
+
+        * xterm.c (XTmouse_tracking_enable): Block input while changing
+        the screens' input selection masks.
+
+        * window.c (change_window_height): If the window being resized is
+        the only window of the screen, no size change is possible; make
+        the delta be zero.  Exit without "changing" the sizes of any
+        windows if the delta is zero.
+
+        * alloc.c: Don't bother to include xterm.h.
+        (Fgarbage_collect): Don't bother to BLOCK_INPUT here,
+        since we don't cons in the input handler.
+
+1991-10-21  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)
+
+        * window.c (init_window_once): Set last_nonminibuf_screen to the
+        initial terminal screen, so that poor Fdisplay_buffer doesn't try
+        to create a new screen on a terminal.
+
+1991-10-19  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+        * m-intel386.h (signal): Optionally don't define it.
+        * s-isc2-2.h (DONT_DEFINE_SIGNAL): Define this.
+
+1991-10-18  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)
+
+        * scroll.c (line_ins_del): Don't calculate costs off the end of mf
+        and ov; use < in loop condition, not <=.
+
+        * scroll.c (scroll_cost): Logic rearranged.
+
+        * dispnew.c (change_screen_size): Change "SCREEN_IS_TERMCAP
+        (screen) == output_termap" to "SCREEN_IS_TERMCAP (screen)"
+        (window_change_signal): Use SCREEN_IS_TERMCAP predicate instead of
+        testing output_method_directly.
+
+1991-10-15  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)
+
+        * xterm.h (STANDARD_EVENT_SET): Include ButtonReleaseMask in
+        STANDARD_EVENT_SET.
+        * xterm.c (XTmouse_tracking_enable): Don't bother or'ing
+        ButtonReleaseMask with the STANDARD_EVENT_SET.
+
+        * dispnew.c (buffer_posn_from_coords): If the coordinates are off
+        past the end of a line, return them as being *before* the newline,
+        not after.
+
+        * keyboard.c (kbd_buffer_get_event): Set input_pending after
+        reading the event, no matter what sort of event it is - i.e., move
+        the assignment to input_pending outside of the event lispifying
+        conditional.
+
+        * keyboard.c (note_mouse_position): Don't record a "new" mouse
+        position unless it really differs from the last one returned.
+
+        * keyboard.c (kbd_buffer_read_char): Renamed to
+        kbd_buffer_get_event, for consistency with kbd_buffer_store_event.
+
+        * window.c (Fwindow_at): modified to take the coordinates as a
+        pair, not a two-element list, for ease of use and compatibility
+        with events.  Make SCREEN argument second and optional.
+        (Fcoordinates_in_window_p): Modified to take and return the
+        coordinates as above, and to distinguish the right border as well
+        as the mode line.
+        (window_from_coordinates): Modified to distinguish the right
+        border as well as the mode line.
+        * lisp.h (Qmode_line, Qvertical_split): Declare this extern, from
+        keyboard.c.
+        * keyboard.c (make_lispy_event): Distinguish a window's right
+        border from its text area.
+
+        * window.c (coordinates_in_window): Make it static.
+
+        * window.c (Flocate_window_from_coordinates): Renamed to
+        Fwindow_at.
+        (syms_of_window): Adjusted.
+        * lisp.h: Adjusted to say so.
+
+        * screen.c (Fcoordinates_in_window_p, window_from_coordinates,

+        (syms_of_window): Adjusted.
+        * lisp.h: Adjusted to say so.
+
+1991-10-14  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)
+
+        * xterm.c (XTclear_end_of_line): This used to try to get the
+        cursor out of the way by comparing the line being cleared with
+        s->cursor_y, which is meaningless; it should have compared it with
+        s->phys_cursor_y.  Changed to just mark the cursor as cleared if
+        it's in the area we're clearing.
+
+1991-10-13  Richard Stallman  (rms at mole.gnu.ai.mit.edu)
+
+        * m-intel386.h: Fix typo in #endif.
+
+1991-10-12  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)
+
+        * callint.c (Fcall_interactively): Added new interactive spec 'K',
+        for mouse clicks.  Added explanation to doc string.  Removed 'e'
+        spec, which didn't work with the new input model anyway.
+        * keyboard.c (Fmouse_click_p): New function.
+        (syms_of_keyboard): defsubr it.
+
+        * keyboard.c (EVENT_QUEUES_EMPTY): Clarified comment.
+        (tracking_off): Change "if (!readable_events)" to
+        "if (!readable_events ())".
+        (Ftrack_mouse): Doc fix.
+        (kbd_buffer_read_char): Fix brainos in tossing of unwanted events.
+        Don't use EVENT_QUEUES_EMPTY to set input_pending; call
+        readable_events.
+
+1991-10-11  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)
+
+        * keyboard.c (Qmode_line): New quoted symbol.
+        (syms_of_keyboard): Initialize and staticpro it.
+        (make_lispy_event): Use it to indicate when a mouse position is in
+        a window's mode line.
+
+        * xterm.c (XTread_socket): Consider the window to be resized if
+        either the character or pixel dimensions have changed; this will
+        catch font size changes.
+
+1991-10-08  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)
+
+        * process.c (wait_reading_process_input): Removed all the
+        exceptional condition stuff.  Emacs lacks any way to respond to
+        such a state, and selecting for it without responding to it can make
+        Emacs loop indefinitely.
+
+        * xterm.c (XTread_socket, construct_mouse_click): Make sure that
+        all enqueued events have their timestamp field set.
+        * termhooks.h (struct input_event): Doc fix.
+        * keyboard.c (last_event_timestamp): New variable.
+        (get_mouse_position, kbd_buffer_store_event,
+        kbd_buffer_read_char): Make sure to fill in Vlast_event_screen and
+        last_event_timestamp.
+        * xselect.c (mouse_timestamp): Don't use this anymore.
+        (last_event_timestamp): Use this instead.
+        (Fx_own_selection, Fx_own_clipboard, Fx_get_selection,
+        Fx_get_clipboard): Use last_event_timestamp instead of
+        mouse_timestamp.
+
+        * xdisp.c (redisplay): Don't pass extra arguments to
+        update_screen.
+
+        * keyboard.c (echo_truncate): Don't call echo here; this results
+        in extraneous echoing of characters.
+        (read_key_sequence): After calling echo_truncate, call echo_char
+        to put the character we just read into the minibuffer, if
+        appropriate.
+
+        * keyboard.c (read_key_sequence): Removed unused argument
+        no_redisplay.
+
+1991-10-01  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)
+
+        * xfns.c (x_create_screen): Initialize phys_cursor_x to -1, to
+        indicate that the screen has no displayed cursor.
+
+        * xfns.c (x_create_screen): Let InternalBorderWidth default to 1.
+
+        * xterm.c (x_display_bar_cursor): Declare this to be static void.
+
+        * xterm.c (XTupdate_begin): Don't turn off the cursor.  This makes
+        ugly flickering.  Instead, make it okay for XTins_del_lines to do
+        so:
+        * screen.h (struct screen): New field phys_cursor_glyph, keeping
+        track of the glyph under the currently displayed cursor.  Since
+        current_glyphs is sometimes inaccurate when we want to undraw the
+        cursor (as when XTins_del_lines is called from do_scrolling), we
+        can't always get the GLYPH from there.
+        * xterm.c (x_draw_single_glyph): Take the glyph to draw as an
+        argument, instead of taking it from the screen matrix.
+        (x_display_box_cursor): Set and use s->phys_cursor_glyph.
+
+        * ymakefile: Note that scroll.o and xmenu.o depend on screen.h.
+
+1991-09-29  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)
+
+        * keyboard.c (make_lispy_event): When building mouse movement

+
+1991-09-26  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)
+
+        * screen.c (Fscreen_parameters): Return the proper value for the
+        'minibuffer parameter for minibuffer-only screens.
+
+        * xdisp.c (redisplay_window): When the start position is forced,
+        constrain it to be within the visible region anyway.
+
+        * xterm.c (XTwrite_glyphs): Instead of turning off the cursor
+        before we write, just notice if we wrote over it.
+
+        * xfns.c (x_decode_color): If a screen has two planes, then it is
+        considered a color screen, and we should look up the color value.
+
+        * ymakefile: Include xselect.o and xrdb.o in XOBJ even when
+        HAVE_X_MENU is not defined.
+
+        * fns.c (Fdelete): This used to be named Fdelq; Roland forgot to
+        change the function name in his August 17 change.
+        (syms_of_fns): defsubr Fdelete.
+
+1991-09-24  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

+
+1991-08-17  Roland McGrath  (roland@geech.gnu.ai.mit.edu)
+
+        * fns.c (Fdelete): New fn.  We have member now; we should have
+        delete too.
+
+1991-08-16  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)
+
+        * xfns.c (x_get_arg): Clean bad characters out of the screen name
+        before using it as a resource key.
+
+        * abbrev.c (Fexpand_abbrev): Don't let capitalization go past point.
+
+        * sysdep.c (sys_suspend): Don't use & before array name.
+
+        * sysdep.c [BROKEN_FIONREAD]: Undefine FASYNC.
+
+        * m-tandem-s2.h (START_FILES, LIB_STANDARD): Added.
+
+        * s/s-aix3-1.h: Define HAVE_TCATTR.
+
+        * xfns.c (Fx_grab_cursor, Fx_ungrab_cursor): Functions removed.
+
+1991-08-15  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)
+
+        * bytecode.c (Qbyte_code_meter): New.
+        (Bend_of_line, Bset_marker, Bmatch_beginning, Bmatch_end, Bupcase,
+        Bdowncase, BRgoto, BRgotoifnil, BRgotoifnonnil,
+        BRgotoifnilelsepop, BRgotoifnonnilelsepop, BlistN, BconcatN): New
+        byte codes.
+        (Fbyte_code): Implemented new codes listed above.  Added code to
+        count how many times a function is called.
+        (syms_of_bytecode): Initialize and staticpro Qbyte_code_meter.
+ 
+        * xfns.c (x_window): When setting the class hints, use the
+        screen's name as the res_name.
+
+        * xfns.c (x_make_screen_name): New function.
+        (Fx_create_screen): Use x_get_arg to find screen name; if none has

+        * lisp.h [HAVE_SHM] (XPNTR): Defined in terms of pure_size,
+        instead of PURESIZE.
+        (pure_size): extern declaration added here.     
+        * ymakefile: Added puresize.h to dependencies for alloc.c and
+        data.c's .o files.
+
+        * emacs.c (main): Doc fix for kludge to scan for -d.
+
+1991-07-17  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)
+
+        * termhooks.h (struct input_event): #if 0'd out the definition for
+        the screen_selected event type, and added the stipulation that the
+        {non_,}ascii_keystroke events specify the screen they happen in.
+        * xterm.c (x_new_focus_screen): Don't enqueue a screen_selected
+        event.
+        (XTread_socket): Calls to x_new_focus_screen in the EnterNotify,
+        FocusIn, LeaveNotify, and FocusOut event code don't worry about
+        enqueued events any more.
+        * keyboard.c (new_selected_screen): Removed - see below.
+        (Vlast_event_screen): New variable, visible to lisp code.
+        (echo_length, echo_truncate): New functions.
+        (readable_events): Removed screen_selected events from the set of
+        things to skip.
+        (kbd_buffer_store_event): Don't bother collapsing consecutive
+        screen_selected events.
+        (kbd_buffer_read_char): Don't process screen_selected events.
+        (make_lispy_event): Re-arrange scrollbar events to put the window
+        whose scrollbar was diddled right after the identifying symbol,
+        for consistency.
+        (read_key_sequence): Let the selected screen and the location of
+        the event affect the keymap used to find its binding.
+        (Fread_key_sequence): Update docstring.
+        (syms_of_keyboard): Added DEFVAR_LISP for Vlast_event_screen.
+
+1991-07-15  Jim Blandy  (jimb@pogo.gnu.ai.mit.edu)
+
+        * screen.c (next_screen): If !mini_screen, only exclude the global
+        minibuffer screen when the minibuffer is its only window.
+        (Fnext_screen): Make the docstring clearer about what MINISCREEN
+        means.
+
+        * window.c (Fother_window): Indicate that it takes both a required
+        and optional argument, instead of just one required.
+
+1991-07-15  Roland McGrath  (roland@churchy.gnu.ai.mit.edu)
+
+        * buffer.c (Fkill_buffer): Rehacked kill-buffer-hooks to use
+        standard name kill-buffer-hook, and to use set_buffer_internal
+        instead of Fset_buffer.  Use static variable containing symbol
+        instead of intern.
+        (syms_of_buffer, init_buffer_once): Qkill_buffer_hook =
+        'kill-buffer-hook.
+
+1991-07-15  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)
+
+        * keymap.c (Fsingle_key_description): When describing a listy
+        object, take the car to find the symbol that heads it, not the cdr.
+
+        * dispnew.c (buffer_posn_from_coords): Pass col and line to
+        compute_motion in the correct order.
+
+        * keyboard.c (make_lispy_event): When calculating rows and columns
+        for mouse clicks and movement events, don't forget to subtract the
+        position of the window's top left corner before passing them to
+        buffer_posn_from_coords.
+
+        * screen.c (coordinates_in_window): Removed useless test for *y ==
+        screen_height, and screen_height variable; this would be out of
+        range of all the windows anyway.
+
+        * xdisp.c (message1): Removed code to ignore messages before X has
+        started up; this issue has hopefully been addressed by the
+        condition-case in startup.el.
+
+        * editfns.c (init_editfns): Make user_name char * instead of
+        unsigned char *, since that's what most of the usages seem to
+        want.  And when expanding ampersands in AMPERSAND_FULL_NAME mode,
+        don't try to use user_name as a string; use Vuser_name.
+
+        * minibuf.c (assoc_for_completion): New function.
+        (do_completion): Use that to check for exact match.
+
+        * minibuf.c (Ftry_completion):  Fix handling of matches aside from
+        case.  If ignoring case, and all else equal, try to preserve the
+        case of the characters in the input.
+
+        * process.c (status_notify): GCPRO tail.
+
+        * sysdep.c (creat_copy_attrs, rename_sans_version):  Always set
+        protection to O:REWD when creating file.  Added new function
+        rename_sans_version, which strips the version number from the target
+        filename, renames the temporary file to this filename,  and then
+        sets the file protection of this new file to be the same as the file
+        being edited.
+
+        * sysdep.c [VMS]: Include pwd.h from Emacs.  Use sys/file.h if GCC.
+        (F_SETFL) [VMS]: Undefine this, to control conditionals.
+        (getpwnam): Make `full' unsigned.
+        (creat_copy_attrs): Add some casts.
+        (sys_access): Change prvmask and CHECKPRIV to use bitfields.
+        Add some casts, and make dummy an unsigned short int.
+        Don't use & on constants.
+        (vmserrstr): Add a cast.
+        (sys_creat): Define va_count before this function.
+
+1991-07-14  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)
+
+        * sysdep.c (sys_sleep, input_wait_timeout): Don't use & on constant.
+        [VMS]: Include pwd.h from Emacs.  Use sys/file.h if GCC.
+        (bzero, bcopy) [VMS]: Don't take address of `length'.
+
+        * sysdep.c (sys_suspend): Cast value of `signal' to insulate from
+        changed value type in sysV.3.
+
+        * sysdep.c (child_setup_tty): Turn off erase & kill chars for BSD.
+
+        * sysdep.c (discard_tty_input): Use TIOCFLUSH on Apollo.
+        (init_sys_modes): Avoid TIOCSTART on Apollo.
+
+        * sysdep.c: If HAVE_TERMIOS is not defined, define tcgetattr in
+        terms of the TIOCGETP ioctl.
+        (init_sys_modes): Handle VSUSP, V_DSUSP if HAVE_TCATTR.
+        (discard_tty_input, init_baud_rate, child_setup_tty,
+        init_sys_modes, tabs_safe_p, reset_sys_modes):
+        Use tcgetattr, and if HAVE_TCATTR, use tcsetattr.
+
+1991-07-13  Jim Blandy  (jimb at churchy.gnu.ai.mit.edu)
+
+        * s-hpux8.h: New file.
+        * fileio.c [HPUX8]: Don't include errnet.h.
+
+        * unexhp9k800.c (unexec): Local variable i to avoid compiler bug?
+
+        * sysdep.c (insque) [WRONG_NAME_INSQUE]: New function.
+        * s-386ix.h (WRONG_NAME_INSQUE): Define it.
+
+        * xdisp.c (message_buf_print): New variable.
+        (message): Clear it here.
+        * dispextern.h: Declare it here.
+        * print.c (printchar, strout): Set it and test it here.
+
+        * keyboard.c (command_loop_1): Don't clear last_command when start
+        macro.
+
+        * keyboard.c (read_command_char): Exit at eof if noninteractive.
+
+        * indent.c (invalidate_current_column): New function.
+        * editfns.c (Fwiden, Fnarrow_to_region): Call it.
+
+        * process.c (create_process): Use O_NOCTTY whenever defined,
+        unless USG.
+
+        * process.c (Fprocess_send_eof): If using a pipe, close it.
+        (close_process_descs): Check IN and OUT for nonzeroness. 
+
+        * process.c (process_send_signal): Use interrupt chars
+        to send certain signals to the process group.
+        (TIOCGETC): Undefine this if it is not really usable.
+
+        * sysdep.c (discard_tty_input): Do nothing if read_socket_hook.
+
+        * xfns.c (x_set_mouse_color): Change the default pointer shapes to
+        be closer to xterm and emacs 18.
+
+        * xterm.c (x_focus_on_screen, x_unfocus_screen): These no longer
+        call XSetInputFocus, because I think that the X-windows ICCCM
+        says that only the window manager can do this sort of thing.
+
+        * keyboard.c (read_char): When there is an unread command
+        character, goto reread_first when this_command_key_count is zero,
+        not when it is >= 0.
+        (command_loop_1): Reset this_command_key_count only if there is no
+        prefix argument.  This makes echoing of keystrokes work correctly.
+
+1991-07-11  Jim Blandy  (jimb@geech.gnu.ai.mit.edu)
+
+        * eval.c (Finteractive_p): Changed "! XTYPE (foo) == Lisp_Bar" to
+        "XTYPE (foo) != bar".
+
+1991-07-11  Jim Blandy  (jimb at geech.gnu.ai.mit.edu)
+
+        * eval.c (apply1): Don't forget to UNGCPRO before returning.
+
+        * xterm.c (XTupdate_begin): Undisplay the cursor here; do_scrolling
+        will call XTins_del_lines when the screen matrix is inaccurate, so
+        we cannot undisplay the cursor then, but do_scrolling is always
+        called within an update.
+
+1991-07-10  David J. MacKenzie  (djm at nutrimat)
+
+        * termcap.c, tparam.c [!emacs, USG || STDC_HEADERS]: Define bcopy
+        in terms of memcpy.
+
+1991-07-09  Jim Blandy  (jimb at geech.gnu.ai.mit.edu)
+
+        * scroll.c (do_scrolling): Use correct termination condition for
+        loop that uses the glyph pointers for the deleted lines to fill in
+        the inserted lines.
+
+1991-07-08  Richard Stallman  (rms at mole.gnu.ai.mit.edu)
+
+        * editfns.c: Doc fix.
+
+1991-07-03  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)
+
+        * dispnew.c (line_hash_code): Test m->highlight[vpos], not
+        m->highlight.  All lines were getting hash codes of -1, because
+        the highlight vector was never NULL.  Golly.
+
+        * process.c (list_processes_1): Handle status of network streams.
+
+1991-07-02  Richard Stallman  (rms at mole.gnu.ai.mit.edu)
+
+        * doc.c (Fdocumentation_property):
+        Pass only strings to Fsubstitute_command_keys.
+
+1991-07-02  Jim Blandy  (jimb at geech.gnu.ai.mit.edu)
+
+        * editfns.c (init_editfns): If neither of the environment
+        variables are set, DON'T set Vuser_name to Vuser_real_name; it's
+        supposed to reflect the EFFECTIVE uid.
+        Get the full name according to Vuser_name if it differs from
+        Vuser_real_name, not if they are equal.
+        And pass Vuser_name to getpwnam in that case instead of user_name,
+        which might be 0.
+
+        * lisp.h (RETURN_UNGCPRO): New macro.
+    
+        * bytecode.c (Fbyte_code): Do not remove GC protection from the
+        stack when making a function call, because the caller is
+        responsible for protecting the arguments to a MANY-arg'ed
+        function.
+        * eval.c (Fapply): If we use funcall_args, GCPRO it.
+        And when we call Ffuncall with funcall_args, tell it the correct
+        length of funcall_args, no matter which branch allocated it.
+        (Ffuncall): Don't gcpro the arguments before calling
+        Fgarbage_collect.
+        (Feval): If we're calling a subr that takes MANY args, don't
+        UNGCPRO until after we call the subr.
+        (apply1, call0, call1, call2, call3): GCPRO the arg arrays passed
+        to Ffuncall and Fapply.
+        * callproc.c (Fcall_process, Fcall_process_region): Don't GCPRO
+        the argument array.
+        * editfns.c (Finsert, Finsert_before_markers): Don't GCPRO the
+        argument array.  Added comment about when GCPROing is not needed.
+        * mocklisp.c (Finsert_string): Don't GCPRO the argument array.
+
+        * keyboard.c (init_keyboard): Handle SIGQUIT with interrupt_signal
+        on any system that has HAVE_TERMIO, not just on USG systems.
+
+1991-07-01  Richard Stallman  (rms at mole.gnu.ai.mit.edu)
+
+        * editfns.c (init_editfns): Test that user_name isn't 0.
+
+1991-06-29  Richard Stallman  (rms at mole.gnu.ai.mit.edu)
+
+        * search.c: Doc fixes.
+
+1991-06-28  Jim Blandy  (jimb at geech.gnu.ai.mit.edu)
+
+        * keyboard.c (make_lispy_event): Let the posns of mouse clicks and
+        mouse movements be nil when window_from_coordinates returns a
+        NON-window, not when it returns a window.  Since posn is a lisp
+        object, don't call make_number when consing up the event.
+        Don't call make_number on the code member of the event.
+
+        * keyboard.c (struct movement): Make the x, y, and time members
+        Lisp_Objects, since it's easier to convert from a Lisp_Object than
+        to.
+        (note_mouse_position): Adjusted for the above.
+        (make_lispy_event): Removed code to make Lisp_Objects for those
+        members.
+
+        * xterm.c (XTread_socket): When handling LeaveNotify events,
+        remember that the focus member of the event is true when the
+        receiving window now has the focus, not when it is losing it.
+        * xfns.c (Ffocus_screen): Don't signal an error if SCREEN is
+        already the focus screen.
+
+1991-06-26  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)
+
+        * alloc.c (Fmake_rope): Use sizeof (GLYPH) instead of 2 to
+        determine how large the string should be, and changed doc string
+        to describe ropes as strings of glyphs, not just as strings of
+        character pairs.
+        (Frope_elt): Use sizeof (GLYPH) as the element size, instead of
+        assuming that the elements are two bytes.
+        * lisp.h (typedef GLYPH): Moved the definition from here...
+        * config.h (typedef GLYPH): to here, so people can elect to get
+        better performance if they don't want to use huge fonts.
+        * xterm.c (dumpglyphs): Use XDrawImageString or
+        XDrawImageString16, Depending on sizeof (GLYPH).
+        
+        * data.c (Fsetq_default): Call Fset_default to do the assignments,
+        not plain Fset.
+
+        The following changes were contributed by Jamie Zawinski
+        <jwz@lucid.com>:
+
+        * bytecode.c (Fbyte_code): BYTE_CODE_SAFE and BYTE_CODE_METER
+        options added.
+        Added Bmark, Bscan_buffer, Bset_mark to support error-checking for
+        these obsolete bytecodes.
+        Added Bunbind_all to support tail-call optimization (not yet
+        implemented).
+        Did NOT add the relative branch opcodes that were in the version
+        of bytecode.c that Jamie sent.
+        The branching bytecodes now only QUIT if they take the branch.
+        Btemp_output_buffer_show, Bforward_char, Bforward_word,
+        Bskip_chars_forward, Bskip_chars_backward, and Bforward_line
+        passed the wrong number of arguments to their subrs. 
+        Brem, Bbuffer_substring, Bdelete_region, Bnarrow_to_region,
+        Bstringeqlsign, Bstringlss, Bequal, Bnthcdr, Bmember, Bassq,
+        Bsetcar, and Bsetcdr passed arguments to the subr in the wrong
+        order.
+
+1991-06-25  Jim Blandy  (jimb at churchy.gnu.ai.mit.edu)
+
+        * doc.c (Fdocumentation): Added a QUIT test to the loop that finds
+        the symbol's function value.
+
+1991-06-24  Jim Blandy  (jimb at geech.gnu.ai.mit.edu)
+
+        * xterm.c (dumprectangle): Removed call to XFlushQueue here.
+
+        * keyboard.c (command_loop_1): Call Fselect_screen to establish
+        the new selected screen after the key sequence has been read, not
+        at the top of the loop.  This way, a key sequence will happen in
+        the screen it was typed at, or (to be more precise) the screen its
+        last character was typed at.
+
+        * keyboard.c (fast_read_one_key): Function deleted, since it had
+        been #if 0'd out a long time ago.
+        (command_loop_1): Support for fast_read_one_key removed.
+
+        * eval.c (Ffuncall): Do GCPRO the arguments, contrary to the May
+        16 change.  The convention appears to be that the MANY-arged
+        callee must protect its own arguments.
+        (Fapply): Don't protect funcall_args; they are the caller's
+        responsibility.
+        * bytecode.c (Fbyte_code): GCPRO the section of the stack *above*
+        the args to Ffuncall, since it will be protected again once
+        Ffuncall returns and therefore should stay valid.  If it is not
+        protected, string relocation may make it invalid.
+        * mocklisp.c (Finsert_string): GCPRO the arguments, since insert
+        may cause a garbage collection.
+        * editfns.c (Finsert, Finsert_before_markers): GCPRO the
+        arguments, since insert may cause a garbage collection.
+        * callproc.c (Fcall_process, Fcall_process_region): GCPRO the
+        arguments, since insert may cause a garbage collection.
+
+1991-06-20  Jim Blandy  (jimb at wookumz.gnu.ai.mit.edu)
+
+        * buffer.h (struct buffer_text, struct buffer): small change to
+        comments.
+
+        * search.c (Fmatch_beginning, Fmatch_end): Fixed doc strings to
+        indicate that non-regexp searches set these too.
+
+        * window.c (Fset_window_start): If window is not the selected
+        window, set windows_or_buffers_changed, so that redisplay will
+        know that it should redisplay the window.
+
+        * callint.c (Finteractive): Changed doc string to indicate that
+        the interactive prompts are passed through format.
+
+1991-06-20  Roland McGrath  (roland@albert.gnu.ai.mit.edu)
+
+        * buffer.c (syms_of_buffer): buffer-undo-list doc fix.
+
+1991-06-11  Roland McGrath  (roland@albert.gnu.ai.mit.edu)
+
+        * data.c (Fsetq_default): Take multiple SYM, VAL args; syntax now
+        parallel to setq.
+
+1991-05-25  Jim Blandy  (jimb at wookumz.gnu.ai.mit.edu)
+
+        * keyboard.c (kbd_buffer_read_char): Fix wait-for-input loop so
+        that we always process/toss events we don't want to return.
+
+        * screen.c (Fselect_screen): Call Ffocus_screen instead of
+        x_new_selected_screen, which doesn't exist anymore.
+
+        * xfns.c (Ffocus_screen): Declare the type of the SCREEN argument.
+
+        * xfns.c (Fx_track_pointer): Function #if 0'd out - I don't think
+        that this is a feature that we want.
+        (syms_of_xfns): Elide the defsubr for the above.
+
+        * xterm.c (x_mouse_screen, x_input_screen): Variable deleted,
+        since all we really need is x_focus_screen; all other issues are
+        the realm and responsibility of the window manager.
+        (x_new_selected_screen): Renamed to x_new_focus_screen, and
+        modified not to do thiogs inappropriate for signal handlers.
+        (XTread_socket): Change the handling of EnterNotify, LeaveNotify,
+        FocusOut and FocusIn events to use x_new_selected_screen, and
+        ditched code that deals with x_mouse_screen and x_input_screen,
+        since they don't exist anymore.
+        (x_display_bar_cursor, x_display_box_cursor): Compare s with
+        x_focus_screen to see what form the cursor should take.
+        (x_destroy_window): Don't bother with x_input_screen.
+        * xfns.c (x_mouse_screen): Removed extern declaration for this.
+        (Fx_grab_pointer): Confine the pointer to x_focus_screen, not
+        x_mouse_screen.  This is wrong, but will make emacs compile until
+        this gets fixed.
+
+1991-05-23  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)
+
+        * keyboard.c (get_input_pending): Don't use trim_events; use
+        readable_events instead.
+
+        * keyboard.c (make_lispy_event): Remove case for window_sys_event,
+        since that type of event doesn't exist anymore.
+
+        * minibuf.c (Fcompleting_read): Document the backup-n argument.
+
+        * dispnew.c (init_display): Don't declare alternate_display extern
+        here.  I can't figure out what this feature is, and it's broken.
+        * emacs.c (main): Don't test alternate_display and put its value
+        in the environment.
+
+1991-05-22  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)
+
+        * keyboard.c (struct movement): Made .used an int instead of a
+        char, since that's more likely to be stored atomically on SPARCS
+        and similar machines. 
+
+        * termhooks.h (struct input_event): Removed the window_sys_event,
+        since it's not used anywhere.  Added screen_selected event type.
+        The event handling code used to change the current buffer,
+        selected window, and selected screen out from under running lisp
+        code.  Now we wait for a more convenient time by enqueuing an
+        event.
+        * xterm.c (XTread_socket): When handling FocusIn events and
+        EnterNotify events with the focus member set, enqueue a
+        selected_screen event instead of calling x_new_selected_screen.
+        * keyboard.c (trim_events): Function deleted; it is a bad idea to
+        delete events based on the current tracking state, since tracking
+        might be re-enabled later.
+        (readable_events): New function which searches the input queue for
+        readable events.
+        (tracking_off): Call readable_events to see if we should
+        redisplay.
+        (kbd_buffer_read_char): Toss events that we are not interested in.
+        This is a better place to do it than trim_events, since we know
+        that do_mouse_tracking will not change.  Also, handle
+        screen_selected events.
+        (new_selected_screen): New variable, holding the screen which
+        should become selected the next time through command_loop_1.
+        (syms_of_keyboard): Initialize and staticpro new_selected_screen.
+        (command_loop_1): If there is a new screen to be selected, do so.
+
+1991-05-21  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)
+
+        * xdisp.c (message): Removed the if at the top that did not
+        display messages if the current screen was a termcap screen and a
+        window system will be used.  The change to startup.el on May 18,
+        1991 replaces this.
+
+        * ralloc.c (check_memory_limits): If the address returned by the
+        allocator is not representable in a Lisp_Object, call memory_full
+        instead of printing a very silly "warning" message.
+
+1991-05-19  Jim Blandy  (jimb at wookumz.gnu.ai.mit.edu)
+
+        * xterm.c (XTread_socket): Don't overwrite the end of the buffer
+        with function keys.
+
+        * keyboard.c (tracking_off): Update input_pending after reading
+        all the input.
+        * process.c: #include "screen.h".
+        (wait_reading_process_input): Check if any screens have been newly
+        mapped and need updating.
+        * xterm.c (XTread_socket): Don't SET_SCREEN_GARBAGED when the
+        screen is unmapped; do this when is mapped.
+        (dumprectangle): Don't dump any data for garbaged screens.
+
+1991-05-18  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)
+
+        * sysdep.c (init_sys_modes): Moved the clauses that set up
+        interrupt-driven input out of the "if running on a terminal"
+        clause, since these may need to be set up even when running on a
+        window system.
+
+1991-05-17  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)
+
+        * process.c (Fprocess_status): For network connections, return
+        Qopen and Qclosed instead of Qrun and Qexit, as documented.
+
+        * lread.c (read1): Removed code that treated numbers starting with
+        a zero as octal.
+
+1991-05-16  Jim Blandy  (jimb at geech.gnu.ai.mit.edu)
+
+        * eval.c (Ffuncall): Don't gcpro the arguments; the caller
+        protects them.
+        (Fapply): Gcpro funcall_args, if we use them.
+
+        * xterm.c (notice_mouse_movement): #if 0'd this function out.
+        (XTread_socket): #if 0 the code that fakes motion events for
+        moving in and out of windows.  Also, rearrange the MotionNotify
+        case to give character rows and columns to note_mouse_position,
+        not pixel x and y positions.  Don't deal with scrollbars here.
+        * termhooks.h (struct input_event): Removed the mouse_movement
+        event kind.
+        * keyboard.c (movement_buf): A new buffer for mouse-movement events.
+        This is hairier than you might think; see the comments for this
+        and the comments for note_mouse_position and get_mouse_position
+        for an explanation of why this is hairy.
+        (movement_ptr): Where the event handler should store new mouse
+        locations.
+        (EVENT_QUEUES_EMPTY): New macro, to be used in the places that
+        used to compare kbd_fetch_ptr to kbd_store_ptr to see if there
+        were any events available; this macro tests the mouse movement
+        buffer too.
+        (Qmouse_movement): New symbol to head mouse movement events with.
+        (trim_events): Mouse movement events are no longer in kbd_buffer,
+        so don't try to trim them.
+        (tracking_off, kbd_buffer_read_char, get_input_pending): Use
+        EVENT_QUEUES_EMPTY.
+        (get_mouse_position): New function to retrieve a mouse position
+        from the buffer properly, no matter when the event-handling signal
+        occurs.
+        (kbd_buffer_read_char): If there is something in kbd_buffer, make
+        an event for that; if there is a mouse movement, make an event for
+        that; otherwise, the while loop lied.
+        (make_lispy_event): Added code to produce mouse movement events.
+        (init_keyboard): Clear the mouse movement buffer.
+        (Qmouse_moved, Qredraw_screen, Qmapped_screen, Qunmapped_screen,
+        Qexited_window, Qexited_scrollbar): Removed extern declarations
+        for these, since they're no longer generated.
+        (syms_of_keyboard): Initialize and staticpro Qmouse_movement,
+        remove DEFVAR_LISP for Vignore_mouse_events.
+
+1991-05-14  Jim Blandy  (jimb at geech.gnu.ai.mit.edu)
+
+        * lread.c (read1): Correctly parenthesize the shift when parsing
+        octal numbers, and signal an error if we see a non-octal digit.
+
+1991-05-13  Jim Blandy  (jimb at wookumz.gnu.ai.mit.edu)
+
+        * keyboard.c (trim_events): New function, to remove uninteresting
+        events from the input queue.
+        (get_input_pending): Call trim_events before checking the queue,
+        so as not to advertise input we don't care about.
+        (Ftrack_mouse): A new function to enable mouse tracking for a
+        block of code.
+        (tracking_off): A function for unwind_protection; restore the
+        mouse tracking state to what it was outside of the track-mouse
+        (syms_of_keyboard): defsubr track-mouse.
+        (make_lispy_event): Find the window io which the click occurred
+        when processing mouse_click events, instead of trusting the window
+        tree in the signal-handling code.  Include the buffer position in
+        the click event.
+
+        * xterm.c (construct_mouse_click): Return the click's screen, not
+        its window, and don't bother updating Vmouse_window.  Calculate
+        the row and column of text-area clicks using
+        pixel_to_glyph_translation, since we know that those data
+        structures are alive in signal handlers.
+
+        * screen.c (window_from_coordinates,
+        Flocate_window_from_coordinates): Moved these to window.c, since I
+        need to be able to call them even if we don't have multi-screen
+        support.
+        (syms_of_screen): Removed defsubr for
+        Flocate_window_from_coordinates.
+        * window.c (window_from_coordinates, Flocate_window_from_coordinates):
+        Here they are.
+        (syms_of_window): Here is the defsubr.
+
+        * keyboard.c (note_mouse_position): New function to enqueue
+        mouse movement events properly.
+        (current_movement_event): New variable, to support the above.  See
+        its comment for more explanation.
+
+        * termhooks.h (struct input_event): Change the .window member to
+        .screen, make it a struct screen *, and indicate that those events
+        which used to return    windows now return screens.  It is unsafe
+        for the event reader to traverse the window structure, because it
+        can be called by a signal handler.
+
+1991-05-10  Jim Blandy  (jimb at geech.gnu.ai.mit.edu)
+
+        * keyboard.c (Vignore_mouse_events): Variable deleted.
+        (make_lispy_event): For mouse and scrollbar clicks, return the
+        position as a pair of numbers, not a list of two numbers.
+
+1991-05-09  Jim Blandy  (jimb at wookumz.gnu.ai.mit.edu)
+
+        * keyboard.c (do_mouse_tracking): Define this variable, which
+        controls whether kbd_buffer_read_char will ignore button up and
+        mouse movement events.
+        * termhooks.h: Declare do_mouse_tracking here.
+
+        * xterm.h (STANDARD_EVENT_SET): New constant, giving the event
+        mask all the windows use.
+
+        * xfns.c (Vx_send_mouse_movement_events): Removed this variable;
+        XTmouse_tracking_enable and do_mouse_tracking do its job better.
+        (syms_of_xfns): Remove the DEFVAR_LISP for the above.
+        (x_window): Don't ask for any pointer motion events or button
+        release events by default; use the unmodified STANDARD_EVENT_MASK.
+        The user will ask for them explicitly if he or she wants them.
+        And don't ask for backing store.
+
+        * xterm.c (XTmouse_tracking_enable): New function to
+        request/unrequest detailed mouse tracking information of the
+        server, and set the flag used by XTread_socket.
+        (x_term_init): Set mouse_tracking_enable_hook to
+        XTmouse_tracking_enable here.
+        (XTread_socket): Handle mouse movement events by calling
+        note_mouse_position.
+
+        * xterm.c (XTread_socket): For MapNotify events, go ahead and set
+        the screen's visible flag, so Expose events will work.  Clear the
+        iconified flag.
+
+        * editfns.c (Finsert_char): Return immediately if n <= 0, not just
+        if n < 0, so that the `while' below does not become an infinite
+        loop.
+
+        * term.c (mouse_tracking_enable_hook): Added this variable to
+        allow emacs to request that the window system start or stop
+        detailed mouse tracking.
+        * termhooks.h (mouse_tracking_enable_hook): Declare it here.
+
+        * xfns.c: Declare the functions before initializing
+        x_screen_parm_table to point to them.
+
+        * xterm.c (XTread_socket): Don't send Qmapped_screen,
+        Qunmapped_screen, Qexited_scrollbar, Qexited_window,
+        Qredraw_screen - these are not features that we want to support.
+
+1991-05-07  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)
+
+        * editfns.c (Finsert_char): Let strlen be the minimum of n and
+        256, not the maximum, so we use an n-byte buffer when n < 256, and
+        a 256-byte buffer many times when n > 256.
+
+1991-05-05  Jim Blandy  (jimb at geech.gnu.ai.mit.edu)
+
+        * keymap.c (Fkeymapp): Fixed docstring to give the right
+        definition of a keymap.
+
+1991-05-03  Richard Stallman  (rms at mole.gnu.ai.mit.edu)
+
+        * data.c (Fcompiled_function_p): New function.
+
+1991-05-03  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)
+
+        * xfns.c (struct x_screen_parm_table): New type for recording
+        information about screen parameters.
+        (x_screen_parms): New table describing the existing parameters.
+        (init_x_parm_symbols, x_set_screen_param): Use x_screen_parms
+        instead of a large switch statement.
+        (x_figure_window_size): Make the default case of the switch call
+        abort instead of signalling an error, since window_prompting's
+        value is internally generated.
+
+1991-05-01  Jim Blandy  (jimb at churchy.gnu.ai.mit.edu)
+
+        * keymap.c (describe_map_tree): GCPRO the maps variable;
+        Fkey_description calls Fmapconcat, which eventually calls
+        Ffuncall, which can garbage-collect.
+
+1991-04-28  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)
+
+        * dispnew.c (buffer_posn_from_coords): Use the information in bufp
+        to reduce the distance compute_motion must scan, when possible.
+
+1991-04-27  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)
+
+        * keyboard.c (syms_of_keyboard): Qtop_level is initialized and
+        staticpro'd in syms_of_data too.  Don't staticpro (or initialize)
+        it again here.
+
+        * macros.c (syms_of_macros): Since executing-macro and
+        executing-kbd-macro are actually the same variable, use
+        DEFVAR_LISP_NOPRO for the second one so it doesn't get staticpro'd
+        twice.
+
+        * process.c (syms_of_process): Don't staticpro or initialize Qexit
+        here, since syms_of_eval already does this and it's bad to
+        staticpro something twice.
+        (Qexit): Remove declaration here, so there will be a compilation
+        error if someone rearranges eval.c without fixing the Qexit stuff.
+        * eval.c (syms_of_eval): Add comment here to say that
+        syms_of_process cares about Qexit too.
+
+        * lread.c (init_obarray): Don't staticpro Vobarray, since the
+        DEFVAR_LISP in syms_of_read takes care of that.
+
+1991-04-22  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)
+
+        * window.c (save_window_save): Always get the selected window's
+        value of point from its buffer, not just when it's also the
+        current buffer.
+
+        * lisp.h (Qdisabled): Declare this here so that the keys_of_*
+        files can disable the commands they define.
+        * casefiddle.c (keys_of_casefiddle): Make upcase-region and
+        downcase-region disabled, by default.
+
+1991-04-16  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)
+
+        * bytecode.c (PUSH):  Alliant can't be bothered to implement the
+        preincrement operator right, so use a comma.
+
+        * print.c (syms_of_print): staticpro Qexternal_debugging_output.
+
+        * editfns.c (clip_to_bounds): No longer static - used in window.c.
+        * window.c (unshow_buffer): Use clip_to_bounds to make sure we
+        change point to something legal.
+
+1991-04-14  Richard Stallman  (rms at mole.gnu.ai.mit.edu)
+
+        * sysdep.c: Changes in formatting and comments.
+
+1991-04-12  Jim Blandy  (jimb at wookumz.gnu.ai.mit.edu)
+
+        * editfns.c (Fbuffer_substring): Don't call make_string, because
+        it may cause a compaction and move the buffer, and then copy the
+        wrong data.
+
+        * keyboard.c (read_char): Only GC if we've actually done enough
+        consing since the last gc to make it worthwhile.
+
+1991-04-11  Jim Blandy  (jimb at geech.gnu.ai.mit.edu)
+
+        * keymap.c (access_keymap): Canonicalize the order of the
+        modifiers when you look up a symbol in a keymap, too.
+        (where-is-internal): If the keymap in which we found the
+        definition was reached by meta-prefix-char, replace it with the
+        metized character.
+
+        * eval.c (Fcondition_case): Initialize the `handler_list' member
+        of the catchtag.
+
+        * keyboard.c (read_char): reset recent_keys_index when it is
+        greater than OR EQUAL to the number of elements in recent_keys,
+        stupid.
+
+        * keymap.c (access_keymap): When fetching the car of listy events,
+        no need to call Fcar_safe - extract the car directly.
+        * keyboard.c (read_key_sequence): Don't extract the car from listy
+        events here since 1) it strips information that we need from the
+        events, and 2) access_keymap will take care of that for us.
+
+        * macros.c (Qexecute_kbd_macro): New variable, used by
+        Fexecute_command.
+        (syms_of_macros): Initialize and staticpro Qexecute_kbd_macro.
+        * lisp.h: Add extern declaration for Qexecute_kbd_macro.
+        * keyboard.c (Fcommand_execute): Add an entry to the command
+        history for keyboard macros too.
+
+        * xterm.c (XTread_socket): If we get a MappingNotify event whose
+        request == MappingKeyboard, someone has changed the keyboard
+        mapping, and we should get the new mapping with
+        XRefreshKeyboardMapping.
+
+1991-04-10  Jim Blandy  (jimb at wookumz.gnu.ai.mit.edu)
+
+        * commands.h: Declare last_command_char to be a Lisp_Object, not
+        an integer (ack).
+
+        * cmds.c (Fself_insert_command): If last_command_char is not an
+        integer, beep.
+        * minibuf.c (Fself_insert_and_exit): Same thing.
+
+        * keyboard.c (format_modifiers): New function, factoring out code
+        from modify_event_symbol and reorder_modifiers.
+        (modify_event_symbol): Call format_modifiers instead of doing the
+        work inline.
+        (reorder_modifiers): New function to put the modifiers on a
+        modified symbol in the canonical order.
+
+        * keymap.c (modify_event_symbol): Prepend the modifiers so they
+        appear in the canonical order: `M-C-S-U-'.
+        (store_in_keymap): If IDX is a symbol, put the modifiers in the
+        canonical order before storing.
+
+1991-04-09  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)
+
+        * keymap.c (Flocal_set_key, Fglobal_set_key): When checking types
+        of arguments, allow KEYS to be a vector or string, not just a
+        string.
+        (keymap_table): New static function to replace duplicated code in
+        access_keymap and store_in_keymap.
+        (access_keymap): Use keymap_table.
+        (store_in_keymap): Use keymap_table, and put non-character
+        definitions in dense keymaps *after* the vector.
+
+        * fileio.c (directory_file_name): Remove trailing slashes from
+        single-letter names like "a/" too.  Let slen be the string length,
+        not one less than the string length.
+
+        * keyboard.c (Fset_input_mode): Don't complain that QUIT isn't an
+        ASCII character if it is nil - it is an optional parameter.
+
+        * keymap.c (Faccessible_keymaps): Use meta-characters in the key
+        sequences returned, carefully making sure that the sequences still
+        appear in order of increasing length.
+
+1991-04-04  Richard Stallman  (rms at mole.gnu.ai.mit.edu)
+
+        * vmsfns.c (vms_trnlog): Increased size of str to 256 elements.
+        (vms_symbol): Increased size of str to 1025 elements.
+
+1991-03-24  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)
+
+        * dispnew.c (pixel_to_glyph_translation): Moved this function to
+        xterm.c, since it is specific to X and only called by the X code.
+        * xterm.c (pixel_to_glyph_translation): Here it is.
+
+1991-03-22  Richard Stallman  (rms at mole.gnu.ai.mit.edu)
+
+        * s-usg5-4.h (DATA_SEG_BITS): Definition deleted.
+        * m-intel386.h (DATA_SEG_BITS): Define here if USG5_4.
+
+1991-03-22  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)
+
+        * keymap.c (Faccessible_keymaps): Produce meta-characters in the
+        key sequences instead of [meta-prefix-char CHAR] sequences.
+
+1991-03-21  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)
+
+        * keymap.c (Flookup_key): If KEY is a zero-length array, then
+        return KEYMAP; this is more algebraically satisfying.
+
+        * dispnew.c (Fsit_for): If the time to sit is zero and there is no
+        input available, then return Qt, not Qnil.
+
+        * keyboard.c (read_char): If a quit occurs and we return
+        quit_char, clear Vquit_flag, so we don't end up returning it again
+        and again...  All lisp code does this manually if they call
+        read-char with quits inhibited, so it's the right thing to do.
+
+1991-03-20  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)
+
+        * keyboard.c (read_char): If there is still no input available
+        after an auto-save, do a garbage-collection.
+
+        * undo.c (truncate_undo_list): Always leave at least one undo
+        record in the undo list.  And use sizeof (struct Lisp_Cons), etc.
+        instead of 8, etc.
+
+        * keyboard.c (read_char): When deciding whether to wrap
+        recent_keys_index back to 0, compare it against
+        sizeof (recent_keys)/sizeof(recent_keys[0]),
+        not sizeof (recent_keys).
+        (quit_char): This can't be anything but an ASCII character, so it
+        shouldn't be a Lisp_Object.  The declaration's comment says why.
+        (read_char, init_keyboard): Treat quit_char as an int now.
+        (Fset_input_mode): As above, and signal an error if QUIT is not an
+        ASCII character.
+
+        * callint.c (Fprefix_numeric_value): Use XFASTINT to initialize
+        val, not raw.
+
+        * fileio.c (Fmake_symbolic_link): Don't expand FILENAME; this
+        would make it impossible to make a link to a relative name.
+
+1991-03-19  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)
+
+        * keyboard.c (syms_of_keyboard): Removed the DEFVAR_BOOL for
+        meta-flag.  This cannot be a lisp variable because we need to
+        change the terminal settings whenever this flag changes.  Change
+        this through set-input-mode instead.
+
+1991-03-19  Richard Stallman  (rms at mole.gnu.ai.mit.edu)
+
+        * keyboard.c (read_avail_input): Raise SIGHUP if no input on AIX.
+
+1991-03-19  Jim Blandy  (jimb at churchy.ai.mit.edu)
+
+        * keyboard.c (kbd_buffer_store_event, kbd_buffer_read_char,
+        read_key_sequence, Fexecute_extended_command, Fset_input_mode,
+        init_keyboard, syms_of_keyboard): Use XSET (var, Lisp_Int, exp)
+        instead of XSETINT (var, exp) in those cases where var is not
+        known to already be a Lisp_Int.
+        * search.c (skip_chars): Same.
+        * xterm.c (construct_mouse_click, XTread_socket): Same.
+        * callint.c (Fprefix_numeric_value): Make sure to return a
+        Lisp_Int even when RAW is a cons whose car is not a Lisp_Int.
+        * process.c (sigchld_handler): When searching for a process whose
+        pid is -1, make sure that the pid is an int first, since network
+        streams are in Vprocess_alist too.
+
+        * keyboard.c (syms_of_keyboard): Added DEFVAR_BOOL for
+        meta-flag.  Emacs 18 had this, and I see no entry in the ChangeLog
+        saying that it was purposefully removed.
+
+1991-03-17  Jim Blandy  (jimb at geech.ai.mit.edu)
+
+        * keymap.c (Fcopy_keymap, Faccessible_keymaps, describe_map,
+        append_key): Minor typos and brainos corrected.
+
+        * keyboard.c (read_char): Removed code to find the vector in a
+        (kbd-macro . VECTOR) - style macro, since the macro is represented
+        by the vector itself.
+        (read_char_menu_prompt): Changed to correctly recognize the new 
+        dense keymap structures.
+        (read_key_sequence): Changed code that checks for keymapness to
+        use get_keymap_1 instead of doing the indirection and keymapness
+        testing itself.
+        (Fcommand_execute): A keyboard macro is now a string or a vector.
+        (Fexecute_extended_command): When expanding this_command_keys,
+        remember that it is now an array of Lisp_Objects, not chars.
+
+        * doc.c (Fdocumentation): Rearranged into a switch statement, and
+        made vectors macros, not keymaps.
+
+        * eval.c (Fcommandp): Removed code to recognize 
+        (kbd-macro . VECTOR) as a command, and added code to recognize
+        vectors as commands.
+        * macros.c (Qkbd_macro): Variable deleted.
+        (syms_of_macros): Initialization of Qkbd_macro removed.
+
+1991-03-14  Jim Blandy  (jimb at pogo.ai.mit.edu)
+
+        * minibuf.c (keys_of_minibuf): Changed all calls to
+        initial_define_lisp_key to calls to initial_define_key.
+
+        * keymap.c (describe_map): Adjusted to handle the new style of
+        keymap.
+
+1991-03-14  Richard Stallman  (rms at mole.ai.mit.edu)
+
+        * fileio.c (Fwrite_region): On VMS, don't try rewriting old version.
+
+1991-03-14  Jim Blandy  (jimb at pogo.ai.mit.edu)
+
+        * keymap.c (Faccessible_keymaps): Adjusted to handle the new style
+        of keymap.
+        (Fwhere_is_internal): Handle the new-style of keymaps.
+        Additionally, only check to see if a match is shadowed by a
+        binding in the local keymap when LOCAL_KEYMAP is non-nil, instead
+        of comparing elt against DEFINITION yet again.
+        (describe_map_tree): Handle key sequences that are vectors, as
+        well as those that are strings.
+
+1991-03-13  Jim Blandy  (jimb at churchy.ai.mit.edu)
+
+        * commands.h, keymap.c (meta_map, control_x_map): Make these
+        Lisp_Objects, not Lisp_Vectors.
+        keymap.c (syms_of_keymap): Same.
+
+        * keymap.c (Fuse_global_map): There is no longer any reason to
+        insist that KEYMAP must be a dense keymap; delete the code that
+        does so.
+
+1991-03-12  Jim Blandy  (jimb at wookumz.ai.mit.edu)
+
+        * commands.h, lisp.h: Changed global_map and current_global_map to
+        be Lisp_Objects, not Lisp_Vectors.
+        keyboard.c (read_key_sequence): Same.
+        keymap.c (Fkey_binding, Fglobal_key_binding, Fglobal_set_key,
+        Fuse_global_map, Fwhere_is_internal, describe_buffer_bindings,
+        syms_of_keymap): Same.
+
+        * keymap.c (Fdefine_key): Braino: increment idx and clear metized
+        flag even when the element of the key sequence isn't a character.
+        (Flookup_key): Fix same braino.
+
+1991-03-10  Jim Blandy  (jimb at wookumz.ai.mit.edu)
+
+        * keymap.c (get_keyelt): Use access_keymap to resolve indirect
+        entries, instead of duplicating its code.
+        (Fcopy_keymap): Handle the new keymap structure.
+
+1991-03-09  Richard Stallman  (rms at mole.ai.mit.edu)
+
+        * eval.c (struct catchtag): New field handlerlist.
+        (internal_catch, internal_condition_case): Set that field.
+        (unbind_catch): Use it.
+
+1991-03-08  Richard Stallman  (rms at mole.ai.mit.edu)
+
+        * m-intel386.h (signal): Maybe define if USG.
+
+        * keyboard.c (echo_char): Don't have space at end of echobuf.
+
+1991-03-07  Jim Blandy  (jimb at albert.ai.mit.edu)
+
+        * keyboard.c (syms_of_keyboard): Initialize mouse_syms, instead of
+        doing func_key_syms twice.  Don't deal with scrollbar_syms, since
+        it doesn't exist.
+
+1991-03-06  Jim Blandy  (jimb at pogo.ai.mit.edu)
+
+        * keymap.c (access_keymap, store_in_keymap): Changed to handle the
+        new style of keymaps.
+
+        * fns.c (Fassq, Fcopy_alist): Changed docstring to promise to
+        ignore elements of LIST that are not conses.  See access_keymap
+        and copy_keymap for a cheap excuse.
+
+1991-03-06  Richard Stallman  (rms at mole.ai.mit.edu)
+
+        * s-vms.h (DATA_START): Remove `+ 512'.
+
+1991-03-05  Jim Blandy  (jimb at spiff.ai.mit.edu)
+
+        * keymap.c (Fmake_keymap): Rewritten to construct the
+        new dense keymap structure: (keymap VECTOR . ALIST).  Docstring
+        adjusted accordingly.  This means that the keyboard macro
+        stupidity (see Feb 27, keyboard.c) is no longer needed.
+
+1991-03-03  Richard Stallman  (rms at mole.ai.mit.edu)
+
+        * sysdep.c (MEMORY_IN_STRING_H): New compilation flag.
+        * s-isc2-2.h: New file.
+
+1991-02-27  Jim Blandy  (jimb at churchy.ai.mit.edu)
+
+        * macros.c (Qkbd_macro): New variable, to hold the symbol
+        `kbd-macro', which we use to tag vector-style keyboard macros.
+        (syms_of_macros): Initialize and staticpro Qkbd_macro.
+
+        * eval.c (Fcommandp): Recognize the new keyboard macros.
+
+        * keyboard.c (Fcommand_execute): A keyboard macro is now a string,
+        or a cons whose car is the symbol `kbd-macro' and whose
+        cdr is a vector of events; previously, macros were strings or
+        vectors, but that makes it difficult to tell the difference
+        between macros and dense keymaps.
+        (read_char): Handle the new macros correctly, and re-allocate
+        this_command_keys correctly.
+
+1991-02-26  Richard Stallman  (rms at mole.ai.mit.edu)
+
+        * s-vms.h (calloc): Define like malloc, etc.
+
+1991-02-26  Jim Blandy  (jimb at spiff.ai.mit.edu)
+
+        * xterm.c (XTread_socket): Move enter_timestamp outside of the
+        function; static variables inside functions don't always work in
+        Emacs.
+
+        * editfns.c (in_accessible_range): Deleted - insufficently
+        general.
+        (clip_to_bounds): New function, much like in_accessible_range,
+        except that the upper and lower bounds are arguments.
+        (goto_char, save_restriction_restore): Rewritten to use
+        clip_to_bounds instead of in_accessible_range.
+
+1991-02-25  Jim Blandy  (jimb at pogo.ai.mit.edu)
+
+        * keymap.c (initial_define_lisp_key): Turn KEY into a Lisp_Int
+        before passing it to store_in_keymap.
+
+        * buffer.c (reset_buffer_local_variables): Don't try to initialize
+        the buffer's mouse_map and function_key_map fields, since they
+        don't exist anymore.
+
+        * macro.c (kbd_macro_buffer, kbd_macro_ptr, kbd_macro_end): These
+        are now all pointers to Lisp_Objects instead of chars.
+        (Fend_kbd_macro): Use make_sequence.
+        (store_kbd_macro_char): Argument c is now a Lisp_Object.  Change
+        call to xrealloc to ask for Lisp_Objects instead of chars.  Set
+        kbd_macro_end to the same place in the new buffer as it was in the
+        old one, not to the end of the buffer.
+        (Fexecute_kbd_macro): Allow MACRO to be a string or a vector.
+        (syms_of_macros): Allocate Lisp_Objects instead of chars for
+        kbd_macro_buffer.
+
+        * alloc.c (make_sequence): New function, useful to keyboard.c and
+        macro.c.
+        * keyboard.c (Fread_key_sequence): Use make_sequence.
+        (Fthis_command_keys): Use make_sequence.
+
+1991-02-24  Jim Blandy  (jimb at churchy.ai.mit.edu)
+
+        * keymap.c (Fwhere_is): If the command can't be found, the message
+        is now "foobie is not on any key.", instead of "... any keys.".
+
+        * keyboard.c (input_poll_signal): Pass 0 to read_avail_input,
+        instead of `&junk'.  Removed variable `junk'.
+        (command_loop_1): Updated to handle the unified function key/mouse
+        event/keystroke arrangement.
+        (Finput_pending_p): Removed vestiges of code to handle
+        unread_input_char value of -1, since this doesn't happen anymore.
+        (read_char): Adapted to handle lispy events.
+        (read_char_menu_prompt): Allocate `menu' buffer using alloca,
+        instead of a variable-sized array, which is gcc-specific.
+        (Frecent_keys): Return the most recent "keystrokes" as a vector,
+        to accomodate lispy events.
+        (Fset_input_mode): Accomodate non-characters as quit keys.  If
+        this is a bad thing, init_sys_modes will tell us.
+        (init_keyboard): this_command_keys is now an array of
+        Lisp_Objects; adjust the amount of storage we request to hold it.
+        Remember that quit_char can be any keystroke.
+        (syms_of_keyboard): last_command_char, last_input_char, help_char,
+        menu_prompt_more_char and meta_prefix_char are now DEFVAR_LISPs
+        instead of DEFVAR_INTs.
+        
+1991-02-24  Richard Stallman  (rms at mole.ai.mit.edu)
+
+        * process.c (wait_reading_process_input): Use NETCONN_P.
+
+1991-02-23  Jim Blandy  (jimb at pogo.ai.mit.edu)
+
+        * keyboard.c: (recent_keys, this_command_keys,
+        menu_prompt_more_char, help_char, last_command_char, quit_char,
+        last_input_char): Changed to Lisp_Objects, so we can use function
+        keys for them.
+        (Vglobal_function_map): Variable deleted.
+        (echo_char): Echo function keys too.  The argument C is now a
+        Lisp_Object instead of a char.
+        (Fread_key_sequence): Removed sludge to handle window events
+        specially, and added sludge to handle sequences with
+        non-characters in them.
+        (classify_object): Elided, since this should go away soon.
+        (read_key_sequence): Adapted to look up symbols in keymaps,
+        just like characters.
+
+1991-02-23  Richard Stallman  (rms at mole.ai.mit.edu)
+
+        * process.c (send_process): Handle EAGAIN like EWOULDBLOCK.
+
+1991-02-22  Jim Blandy  (jimb at pogo.ai.mit.edu)
+
+        * doc.c (substitute_command_keys): Call describe_map_tree with
+        only three arguments, since the CHARTAB arg has been disposed of.
+
+        * keymap.c (Fcurrent_global_map, Fuse_local_mouse_map): Functions
+        deleted, since the mouse maps are no longer separate from the key
+        maps.
+        (append_key): New function, which handles tacking a single
+        keystroke on the end of a key sequence, promoting strings to
+        vectors when needed.
+        (Faccessible_keymaps): Adjusted to return vectors for key
+        sequences, when necessary.
+        (Fkey_description): Removed stuff to handle mouse buttons and
+        other things specially, since this work will go into
+        Fsingle_key_description.
+        (Fsingle_key_description): SIMPLIFIED to handle everything
+        correctly!  Jeepers!
+        (Fwhere_is_internal): Scan the assoc-list at the end of dense
+        keymaps, and construct strings or vectors.
+        (where_is_string, describe_buffer_bindings): Simplified by
+        deleting code to handle mouse button bindings specially.
+        (describe_map_tree): Removed CHARTAB argument; this was
+        a kludge to print out mouse events nicely, and is no longer
+        necessary.  Nobody was using it anyway.
+        (describe_map): Removed ugly hack to handle mouse buttons
+        specially, added code to describe alists on dense keymaps, and
+        removed CHARTAB argument.
+        (describe_alist): Made to handle bindings of symbols as well as
+        characters.  Removed CHARTAB argument.
+        (describe_vector): Removed CHARTAB argument, allocated KLUDGE
+        outside of loop and GCPRO'd it.
+        (syms_of_keymap): Remove last vestiges of Vglobal_mouse_map,
+        Vmouse_button_names, Suse_local_mouse_map,
+        Scurrent_local_mouse_map.
+
+        * buffer.h (struct buffer): Removed mouse_map and function_key_map
+        members, since they are now handled by the keymap element.
+
+        * keyboard.c (syms_of_keyboard): Change initialization of
+        meta_prefix_char, since it's now a Lisp_Object.
+
+        * keymap.c (Fkeymapp): Rewrote this to use get_keymap_1; now it's
+        a one-liner instead of a 13-liner.
+        (DENSE_TABLE_SIZE): Created new constant for the # of lookup-style
+        entries in a dense keymap, and the index of the map's assoc list.
+        Used it where appropriate.
+        (Fcopy_keymap): Notice that 129'th element in dense keymaps.
+        (Fdefine_key, Flookup_key): Reworked to deal with vectors of
+        symbols and characters as well as strings for key sequences.
+        (meta_prefix_char): Changed from an int to a Lisp_Object.
+
+1991-02-21  Richard Stallman  (rms at mole.ai.mit.edu)
+
+        * fileio.c (report_file_error): Don't downcase "I/O".
+
+1991-02-20  Jim Blandy  (jimb at geech.ai.mit.edu)
+
+        * keymap.c (access_keymap): Allow IDX to be any sort of bindable
+        event, and deal with the extended keymaps.  IDX is now a
+        Lisp_Object instead of an int, obviously.
+        (store_in_keymap): Allow IDX to be any sort of bindable event, and
+        deal with the extended keymaps.  IDX is now a Lisp_Object.
+
+        * xterm.c (construct_mouse_click): Add code to set the up_modifier
+        bit for ButtonRelease events.
+
+        * keyboard.c (kbd_buffer_store_event): Use XFASTINT and XSETINT to
+        access event->code, since it's a Lisp_Object.
+        (kbd_buffer_read_char): Golly, perhaps we should increment
+        kbd_fetch_ptr to remove the event we just read from the queue.
+        (modify_event_symbol): Stupid fixes: correctly look up unmodified
+        symbols when cache entry has a modified symbol vector.  And, when
+        first adding the modified symbol vector, copy the old slot value
+        into it correctly.
+
+1991-02-19  Jim Blandy  (jimb at pogo.ai.mit.edu)
+
+        * keyboard.c (command_loop_1): #if 0 the block of code which
+        handles mouse events and other lispy events specially, since I
+        hope it will go away soon.
+
+        * dispnew.c (Fsleep_for_millisecs): Pass all four arguments to
+        wait_reading_process_input, instead of just the first two.
+
+        * process.c (wait_reading_process_input): Remove support for
+        only waiting for mouse input, since that has been superceded.
+        This removes X dependencies from process.c, and eliminates some
+        references to code that should only exist when using X10.
+
+        * keyboard.c (mouse_moved_symbol, redraw_screen_symbol,
+        mapped_screen_symbol, unmapped_screen_symbol,
+        exited_window_symbol, exited_scrollbar_symbol): Renamed to
+        Qmouse_moved, Qredraw_screen, Qmapped_screen, Qunmapped_screen,
+        Qexited_window, Qexited_scrollbar, just as done in xterm.c.
+        (classify_object): Removed code to look up a function key in the
+        global and local function key keymaps, since this will be done
+        more generally.
+        (Fexecute_mouse_event): Elided this function with a #if 0;  I
+        think it will go away once the more general keymap stuff is
+        implemented, but I'm not sure.
+        (syms_of_keyboard): Removed defsubr for Sexecute_mouse_event.
+        (where_is_string, describe_buffer_bindings, syms_of_keymap):
+        Elided code to handle mouse button bindings specially; I hope this
+        will go away.
+
+        * lread.c (syms_of_lread): Change defsubr for eval-buffer to
+        defsubr for eval-current-buffer.
+
+        * keymap.c (syms_of_keymap): defvar for Vglobal_function_map
+        removed, since that variable has disappeared.
+
+        * xterm.c (x_func_key_to_sym): Removed entirely, since we no
+        longer convert X keycodes to symbols in this section of code.
+        (x_convert_modifiers): New function to turn the X modifier bits
+        into struct input_event modifier bits.
+        (encode_mouse_button): removed, since this work isn't done here
+        anymore.
+        (Vx_send_mouse_movement_events): Add an extern declaration for
+        this.
+
+        * termhooks.h: Only define struct input_event if the module
+        has previously #included lisp.h; this avoids forcing simple modules
+        like cm.c to #include lisp.h.
+
+        * term.c: #include "lisp.h" before #including "termhooks.h", since
+        the latter uses Lisp_Objects now.
+
+        * xfns.c (syms_of_xfns): Delete the defsubr for Sx_window_id,
+        since Fx_window_id is gone.
+
+        * xterm.c (construct_mouse_event): Construct a struct input_event
+        instead of a lispy event.
+
+        * screen.c (coordinates_in_window):  Added explanatory comment. 
+        (window_from_coordinates): Change PART, whose returned values are
+        dependent on X-windows, to be called MODELINE_P, with appropriate
+        new return values.
+        * xterm.c (notice_mouse_movement): Handle the X-windows dependent
+        stuff that used to be in window_from_coordinates here instead.
+        (XTread_socket): Modified to produce struct input_events
+        instead of lispy events.
+
+1991-02-18  Jim Blandy  (jimb at pogo.ai.mit.edu)
+
+        * termhooks.h: Added up_modifier to the enum for modifier bits;
+        this bit will be applied to mouse events.
+        (struct input_event): Changed specification of non_ascii_keystroke
+        events to send the function key number instead of a symbol.
+        * keyboard.c (modify_event_symbol): Re-arranged to work well
+        with function key/mouse button numbers instead of symbols.
+        And if (MODIFIERS & up_modifer), prepend "U-" to the name of the
+        symbol being constructed.
+        (make_lispy_event): Use the new modify_event_symbol.
+
+        * xterm.c (notice_mouse_movement): Adjusted this function to
+        work with a struct input_event instead of producing an
+        s-expression.
+
+        * xterm.c, xfns.c: Made all references to x_mouse_queue,
+        x_expose_queue, and the functions which manipulate them
+        conditional on having X10, since only X10 code ever places
+        anything in these queues.
+
+1991-02-15  Jim Blandy  (jimb at pogo.ai.mit.edu)
+
+        * termhooks.h: Define struct input_event, to represent input
+        events while they sit in the keyboard input buffer.  Using lisp
+        objects to represent input events is a bad idea because the
+        routines which enqueue them can be called from signal handlers,
+        and therefore should not cons.
+
+        * keyboard.c: (kbd_buffer, kbd_fetch_ptr, kbd_store_ptr): Change
+        these to be of type `struct input_event *'.
+        (kbd_buffer_store_event): Manipulate struct input_events instead
+        of lisp objects.
+        (make_lispy_event): New function, to construct a lisp-style event
+        corresponding to a particular struct input_event.
+        (modify_event_symbol): New function, to add modifier prefixes to a
+        symbol, and look the new symbols up quickly if they've already
+        been created.
+        (kbd_buffer_read_char): Call make_lispy_event to turn the thing
+        in the keyboard buffer into the form that read_char is expecting.
+        (Qwith_modifier_keys): Define this new symbol variable.
+        (syms_of_keyboard): Initialize and protect Qwith_modifier_keys.
+
+        * xterm.c (init_input_symbols): Rearranged the code that produces
+        the func_key_syms array.
+        (x_func_key_to_sym): Simplified, since more will be handled in
+        make_lispy_event.
+        (XTread_socket): When handling KeyPress events, don't pass the
+        state of the modifier keys to x_func_key_to_sym, since it doesn't
+        care any more.
+
+        * sysdep.c (kbd_input_ast, end_kbd_input, read_input_waiting):
+        Rename kbd_buffer_store_char to kbd_buffer_store_event.
+
+        * keyboard.c (stuff_buffered_input): Since the keyboard buffer
+        holds lisp objects, only stuff entries that are Lisp_Ints, and
+        XINT them before passing them to stuff_char.
+        (kbd_buffer_store_char): Make this not a static function, since
+        sysdep.c calls it.  And rename it kbd_buffer_store_event.
+
+        * keyboard.c (kbd_buffer, kbd_fetch_ptr, kbd_store_ptr): Made these
+        variables static, to document the fact that they're only used
+        within keyboard.c.
+
+1991-02-13  Jim Blandy  (jimb at pogo.ai.mit.edu)
+
+        * xterm.c (init_input_symbols): remove the `xk-' prefix from all
+        the function key symbols, since they're going to be used for
+        function keys from all sorts of terminals, not just when running
+        under X.
+
+        * lread.c (read_escape): Removed support for mouse button escapes
+        (\S-, \U-, \C- applied to digits), because they're being replaced
+        by something more rational.
+
+1991-02-09  Richard Stallman  (rms at mole.ai.mit.edu)
+
+        * buffer.c: Doc fix.
+
+        * sysdep.c (dup2): Rewrite of non-F_DUPFD case.
+
+1991-02-08  Richard Stallman  (rms at mole.ai.mit.edu)
+
+        * m-intel386.h (LOAD_AVE_CVT): Add extra parens.
+        * s-usg5-4.h (LIBX11_SYSTEM): #undef it.
+
+1991-02-07  Richard Stallman  (rms at mole.ai.mit.edu)
+
+        * s-esix.h: New version from kayvan.
+        Adds HAVE_X11 conditional, NEED_PTEM_H, USG_SYS_TIME, USE_UTIME,
+        LIBS_DEBUG; removes #undef sigsetmask, LIBS_SYSTEM, ESIX, 
+        MISSING_UTIMES.
+
+1991-02-06  Richard Stallman  (rms at mole.ai.mit.edu)
+
+        * process.c (Faccept_process_output): Second arg gives timeout.
+
+1991-02-06  Jim Blandy  (jimb at geech.ai.mit.edu)
+
+        * lread.c (read_escape): Added support for \S- and \U- escapes (for
+        binding mouse buttons), and noted that \C- must work on digits.
+
+        * xterm.c (init_input_symbols): Was mistakenly renamed
+        init_inputs; named back.
+
+        * xterm.c (construct_mouse_click, encode_mouse_button): Rewritten
+        to build new-style mouse events.
+
+        * dispnew.c (update_line): Write a zero into obody[olen] to make
+        sure the lines in current_screen->glyphs remain terminated.
+        * xdisp.c (display_string, display_text_line): Don't write off
+        the end of the line and destroy the zero terminator when expanding
+        a tab.
+
+        * fns.c (Fy_or_n_p): Accept C-] (usually abort-recursive-edit) as
+        well as C-g to quit.
+
+1991-02-05  Jim Blandy  (jimb at geech.ai.mit.edu)
+
+        * sysdep.c, s-aix3-1.h, s-hpux.h, s-iris3-5.h, s-iris3-6.h,
+        s-irix3-3.h, s-rtu.h, s-sunos4-1.h, s-unipl5-0.h, s-unipl5-2.h,
+        s-usg5-0.h, s-usg5-2-2.h, s-usg5-2.h, s-usg5-3.h, s-xenix.h:
+        Globally replaced INTERRUPTABLE with INTERRUPTIBLE.
+
+        * xterm.c (construct_mouse_event): Renamed to
+        construct_mouse_click, since there are kinds of mouse events
+        besides clicks (movement, for example).
+        (XTread_socket): rename calls here.
+
+        * xterm.c (mapped_screen_symbol, unmapped_screen_symbol,
+        exited_scrollbar_symbol, exited_window_symbol,
+        redraw_screen_symbol, mouse_moved_symbol): Renamed to
+        Qmapped_screen, Qunmapped_screen, Qexited_scrollbar,
+        Qexited_window, Qredraw_screen, Qmouse_moved, to agree with naming
+        conventions elsewhere in Emacs.
+
+        * xfns.c (text_part_sym, modeline_part_sym,
+        vertical_scrollbar_sym, vertical_slider_sym, vertical_thumbup_sym,
+        vertical_thumbdown_sym, horizontal_scrollbar_sym,
+        horizontal_slider_sym, horizontal_thumbleft_sym,
+        horizontal_thumbright_sym): Renamed to Qtext_part, Qmodeline_part,
+        Qvscrollbar_part, Qvslider_part, Qvthumbup_part, Qvthumbdown_part,
+        Qhscrollbar_part, Qhslider_part, Qhthumbleft_part,
+        Qhthumbright_part, to agree with the naming conventions elsewhere
+        in Emacs.
+
+        * xterm.c (XTread_socket): While handling EnterNotify events,
+        clear Vmouse_event here.
+        (notice_mouse_movement): Don't clear it here.
+
+1991-02-04  Richard Stallman  (rms at mole.ai.mit.edu)
+
+        * s-sunos4-0.h: Renamed from s-sunos4.h.
+        (read, write, open, close): Macro defs moved to s-sunos4-1.h.
+        (INTERRUPTABLE_*): Likewise.
+        * s-sunos4-1.h: New file.
+
+1991-02-04  Jim Blandy  (jimb at churchy.ai.mit.edu)
+
+        * keymap.c (Vglobal_mouse_map, Vglobal_function_map): Variables
+        removed in preparation for conversion to unified keymap format.
+        (Fmake_keymap): Make vector keymaps with 129 entries; the last
+        will be an assoc-list for looking up symbols.  Update docstring to
+        describe 129'th element.
+        (Fmake_sparse_keymap): Update docstring to say that you can bind
+        symbols in these maps too.
+        (Fkeymapp): Recognize 129-element vectors as keymaps, not
+        128-element vectors.
+        (get_keymap_1): wrong_type_argument can no longer return a new
+        value supplied by the debugger; remove loop to support this.
+
+        * xterm.c (XTread_socket): When handling EnterNotify events,
+        enqueue fake mouse events iff Vx_send_mouse_movement_events !=
+        Qnil.
+
+        * xfns.c (Fx_window_id): Function removed; Fscreen_parameters
+        already provides this information.
+
+        * xterm.c (x_term_init): Cleaned up the code to get the host name,
+        and removed fixed limit on host name length.
+
+        * window.c (Fscroll_other_window): Don't explicitly save
+        current_buffer and point; the save_excursion will take care of
+        that anyway.
+
+        * dispnew.c (safe_bcopy): Rewritten to handle overlapping regions
+        with multiple calls to bcopy instead of a stupid copy loop.
+
+        * xterm.c, xfns.c (Vscreen_part, Vx_send_movement_events): These
+        variables renamed to Vmouse_screen_part,
+        Vx_send_mouse_movement_events.
+
+        * lread.c (Feval_buffer): function deleted.
+        (Feval_current_buffer): Removed "#if 0 ... #endif" around this
+        function.
+
+1991-02-03  Richard Stallman  (rms at mole.ai.mit.edu)
+
+        * Makefile, ymakefile (SHELL): Force use of sh.
+
+        * s-usg5-4.h (USG5_4): Define it.
+        (LOAD_AVE_*): Don't define them.
+        * m-intel386.h (LOAD_AVE_*): Define, if USG5_4.
+
+        * buffer.c (Fbuffer_local_variables): Omit slots with no names.
+
+1991-02-03  Jim Blandy  (jimb at geech.ai.mit.edu)
+
+        * xterm.c (x_term_init, init_input_symbols): Moved these to the
+        bottom of the file, 1) to be consistent with the other files, and
+        2) so it can initialize some variables I want.
+
+1991-02-02  Jim Blandy  (jimb at churchy.ai.mit.edu)
+
+        * xterm.h: Added external declaration for x_focus_screen.
+
+        * search.h: File deleted.
+        * buffer.h: declare searchbuf here instead.
+
+        * screen.c (Ffocus_screen, Funfocus_screen): Moved these functions
+        to xfns.c, since they're x-specific.
+        (syms_of_screen): Removed defsubr calls for above.
+        * xfns.c (Ffocus_screen, Funfocus_screen): Here they are.
+        (syms_of_xfns): The defsubrs are here now.
+
+        * buffer.h (PT): Make this expand to an expression which is not an
+        l-value, to prevent people from assigning to it.  If everyplace
+        uses SET_PT, it will be easier to merge in the interval code.
+        (point): Similar changes here.
+        (SET_PT): This can no longer be written in terms of PT, so write
+        out current_buffer->text.pt.
+
+        * xterm.c (x_new_font): Rewritten to remove arbitrary limit on
+        size of x_font_table.
+        (x_font_table_size): Created new variable.
+        (n_available_fonts, font_names, font_info, MAX_FONTS): Deleted
+        these variables/macros.
+
+        * dispnew.c (scroll_screen_lines): Instead of disabling the lines
+        vacated by the scroll (i.e. zeroing enable), mark them as enabled
+        but empty.
+
+        * callint.c (Fcall_interactively): Move UNGCPRO down, so that
+        stuff is protected while we build the command history entry and do
+        the function call.
+
+        * xterm.c (XTupdate_end): Turn cursor on, even if we don't
+        currently have the focus.
+
+        * minibuf.c (temp_echo_area_glyphs): Clear echo_area_glyphs and
+        previous_echo_glyphs, so the message we're displaying will
+        supercede any existing message.
+
+        * keyboard.c: Removed external declaration of echo_area_glyphs,
+        since it's declared in window.h.
+
+1991-01-31  Jim Blandy  (jimb at pogo.ai.mit.edu)
+
+        * xterm.c (XRINGBELL): Pass 0 as the second argument to XBell;
+        respect the user's preferences.
+
+1991-01-30  Jim Blandy  (jimb at pogo.ai.mit.edu)
+
+        * xterm.c (x_draw_single_glyph): New function, created to simplify
+        cursor drawing/undrawing.
+        (x_display_box_cursor): Rewritten to properly handle the box
+        cursor in its filled and hollow forms.
+        * xterm.h (enum text_cursor_kinds): Added enum for the different
+        kinds of cursors which might be displayed in a window.
+        (struct x_display): added member `text_cursor_kind' which says
+        which kind of cursor is currently being displayed in the window, so
+        we can arrange to redraw it effectively.
+
+        * keyboard.c (command_loop_1): When handling the forward_char
+        command, don't let point move to the location after the end of the
+        buffer.
+
+        * keyboard.c (poll_suppress_count): Define this even if
+        POLL_FOR_INPUT is not defined, because this makes lots of #ifdef
+        clauses unnecessary, and doesn't hurt, because
+        {start,stop}_polling become nops.
+
+        * config.h, config.h-dist: Make these #include "system.h" and
+        "machine.h", and let the config script link these appropriately,
+        instead of using the machine-specific names and expecting the user
+        to edit this file.
+
+1991-01-29  Jim Blandy  (jimb at churchy.ai.mit.edu)
+
+        * window.c (Fdelete_window): sib is a Lisp_Object; treat it as
+        such.
+
+        * xterm.c (screen_unhighlight): When the focus leaves a screen,
+        draw the cursor as a box instead of making it disappear entirely.
+
+1991-01-29  Richard Stallman  (rms at mole.ai.mit.edu)
+
+        * unexec.c (make_hdr) [TPIX]: Set f_hdr.f_nscns and f_thdr.f_scnptr.
+
+        * sysdep.c [BROKEN_TIOCGWINSZ]: Undef TIOCGWINSZ.
+
+        * process.c (wait_reading_process_input): Don't ignore
+        a zero-length read on a network connection.  Do close it.
+
+        * sysdep.c (hft_init, hft_reset): Pass &junk as arg to HFQERROR.
+        Do nothing if not HFT.
+
+1991-01-29  Jim Blandy  (jimb at albert.ai.mit.edu)
+
+        * xfns.h: Created, to declare things defined in xfns.c.
+        Declare Vx_send_movement_events.
+        * xfns.c: #include "xfns.h".
+        (Vx_send_movement_events): Define this variable.
+        (syms_of_xfns): DEFVAR_LISP it.
+        * xterm.c: #include "xfns.h".
+        (XTread_socket): Place a mouse-moved event in the buffer iff
+        Vx_send_movement_events says to.
+
+1991-01-28  Jim Blandy  (jimb at geech.ai.mit.edu)
+
+        * ymakefile: noted that callint.o depends on mocklisp.h,
+        and dired.o on search.h.
+
+        * environ.h: Deleted - its creation in the first place was misguided.
+        callproc.h: Removed #include "environ.h", and added declarations
+        for environ.h
+
+        * buffer.c (syms_of_buffer): Add more detailed documentation to
+        buffer-undo-list.
+
+        * lisp.h (poll_suppress_count): Add external declaration for this here.
+
+1991-01-28  Richard Stallman  (rms at mole.ai.mit.edu)
+
+        * m-sun3-68881.h, m-sun3-fpa.h, m-sun3-soft.h: New files.
+
+1991-01-27  Jim Blandy  (jimb at geech.ai.mit.edu)
+
+        * lisp.h (struct handler): add poll_suppress_count member, so
+        we can restore poll_suppress_count when we handle an error.
+        * eval.c (struct catchtag): Add it here too, for throws.
+        (internal_catch, Fcondition_case, internal_condition_case): Record
+        the value of poll_suppress_count here in the handler and catch tag.
+        (Fthrow, Fsignal): Restore it here.
+
+1991-01-25  Jim Blandy  (jimb at churchy.ai.mit.edu)
+
+        * xterm.c (x_display_box_cursor): If we're undrawing the cursor by
+        redrawing the character underneath it, draw according to that
+        line's highlight, instead of assuming it's in the normal GC.
+
+1991-01-25  Richard Stallmao  (rms at mole.ai.mit.edu)
+
+        * buffer.h (PTR_CHAR_POS): Value was too small by 1.
+
+1991-01-16  Richard Stallman  (rms at mole.ai.mit.edu)
+
+        * doprnt.c (doprnt): Check for overflow in fmtcpy.
+
+1991-01-16  Jim Blandy  (jimb at churchy.ai.mit.edu)
+
+        * window.c (Fdelete_window): If the deletee gives its space to its
+        next sibling, that sibling needs to have its top/left side pulled
+        back to where the deletee's is.
+
+1991-01-15  Jim Blandy  (jimb at geech.ai.mit.edu)
+

+        bytecode objects too.
+
+        * syntax.h (syntax_spec_code): make external declaration for this
+        unsigned char to match the definition in syntax.c.
+
+        * indent.c (compute_motion): added comments describing how it
+        can be used.
+
+1991-01-15  Richard Stallman  (rms at mole.ai.mit.edu)
+
+        * process.c (create_process): Use SETUP_SLAVE_PTY if defined.

+        (FIRST_PTY_LETTER): Overridden.
+        (PTY_NAME_SPRINTF, PTY_TTY_NAME_SPRINTF, SETUP_SLAVE_PTY): New macros.
+
+        * m-ibmrs6000.h (CANNOT_DUMP): Undefine it.
+        (UNEXEC): Define it.
+        (PURE_SEG_BITS, SHMKEY): Define only if CANNOT_DUMP.

+        And rotate by amount, not -amount, in the up-scrolling section.
+
+        * xterm.h (MAX_FONTS, x_font_table, n_fonts): Removed external

+
+        * xdisp.c (redisplay, display_mode_line): To test
+        Vglobal_minibuffer_screen for validity, you must check that its

+
+        * screen.c (syms_of_screen): Initialize Vglobal_minibuffer_screen
+        to Qnil; otherwise, it inhibits decent redisplay (is that another
+        bug?)
+
+        * dispnew.c (init_display): Make sure that the standard input is a
+        terminal here.

+        sprintf.
+
+        * xfns.c (x_window): Don't use backing store or saveunders; they

+        (x_make_gc): Initialize gc_values.line_width to zero before

+1991-01-04  Jim Blandy  (jimb at pogo.ai.mit.edu)
+
+        * window.c (window_loop): neatened up.  MINI being non-zero now
+        makes it recognize active minibuffer windows.  Iterates properly
+        over multiple screens when asked nicely.

+
+        * window.c (Fnext_window, Fprevious_window): Accept non-nil, non-t
+        values for mini, and don't turn off all-screens when mini is t but
+        there is no global minibuffer screen.  Remove screen_{root,mini}
+        variables.
+        (Fother_window): Added second argument all_screens.
+

+        only define these functions ifdef HAVE_X_WINDOWS.
+        (window_from_coordinates): use next_screen_window instead of
+        Fnext_window, so that global minibuffers work.
+
+        * lread.c (syms_of_read): Don't forget to defsubr
+        read-char-exclusive.
+
+        * lisp.h (Fscreenp, Fselect_screen, Ffocus_screen,

+        * lisp.h (Qkeyp): Added external declaration for this.
+
+        * keyboard.c (Frecursive_edit): Don't specbind the standard IO here.

+
+        * fileio.c (Fwrite_region): We should dereference GPT_ADDR[-1]
+        before comparing it to '\n' for VMS cruft.
+        (Fdo_auto_save): Don't call run-hooks before it's defined.  This

+        Call error instead if user tries to use debugger to return.
+
+        * eval.c (unbind_to): New second arg is value to return.  gcpro it.
+        All callers changed to pass the arg; if a caller uses unbind_to
+        just before returning, it passes as this arg the value it wants

+
+1990-12-28  Jim Blandy  (jimb at geech.ai.mit.edu)

+
+        * dispnew.c (window_change_signal): used to assume that SIGWINCHes

+        buffer viewed by Vmouse_window instead.
+
+        * alloc.c (xmalloc, xrealloc): removed calls to
+        {un,}hold_window_change.  The new SIGWINCH-handling code and

+
+        * indent.c (position_indentation): renamed stray `bf_cur' to
+        `current_buffer', and old `CharAt' usages to `FETCH_CHAR'.
+        * buffer.c (Fbuffer_disable_undo): the symbol object for this
+        subroutine was still named Sbuffer_flush_undo, and the symbol's

+        buffer.c (last_known_column_point): removed extern declaration for
+        this variable, included indent.h.
+        (Vprin1_to_string_buffer): removed extern declaration - it's
+        already in lisp.h.
+
+        * lisp.h (catchlist, backtrace_list, stack_bottom,
+        current_global_map): added extern declarations for these
