 ** Emacs can be compiled with file notification support.
-The configure option `--with-file-notification=LIB' enables file
-notification support in Emacs.  This option's value should be `yes',
-`no', `gfile', `inotify' or `w32'.  `yes' is a synonym for `w32' on
-MS-Windows, and for `gfile' otherwise.  The default value is `yes'.
+This happens by default if a suitable system library is found at
+build time.  To prevent this, use the configure option
+`--with-file-notification-no'.  See below for file-notify features.
+FIXME?  This feature is not available for the Nextstep port. (?)
 
 ** The configure option --with-crt-dir has been removed.
 It is no longer needed, as the crt*.o files are no longer linked
 specially.
 
-** Emacs for MS-Windows can now be built by running the configure script
-using the MSYS environment and MinGW development tools.
-This is from now on the preferred method of building Emacs on
-MS-Windows.  The Windows-specific configure.bat and makefile.w32-in
-files are deprecated.  See the file nt/INSTALL.MSYS for detailed
-instructions.
-
-Using the Posix configure script and Makefile's also means a change in
-the directory structure of the Emacs installation on Windows.  It is
-now the same as on GNU and Unix systems.  In particular, the auxiliary
-programs, such as cmdproxy.exe and hexl.exe, are in
-libexec/emacs/VERSION/i686-pc-mingw32 (where VERSION is the Emacs
-version), version-independent site-lisp is in share/emacs/site-lisp,
-version-specific Lisp files are in share/emacs/VERSION/lisp and in
-share/emacs/VERSION/site-lisp, Info docs are in share/info, and data
-files are in share/emacs/VERSION/etc.  (Emacs knows about all these
-directories and will find the files in there automatically; there's no
-need to set any variables due to this change.)

+        Clean up errno reporting and fix some errno-reporting bugs.
+        * callproc.c (Fcall_process):
+        * fileio.c (Fcopy_file, Finsert_file_contents, Fwrite_region):
+        * process.c (create_process, Fmake_network_process):
+        * unexaix.c (report_error):
+        * unexcoff.c (report_error):
+        Be more careful about reporting the errno of failed operations.
+        The code previously reported the wrong errno sometimes.
+        Also, prefer report_file_errno to setting errno + report_file_error.
+        (Fcall_process): Look at openp return value rather than at path,
+        as that's a bit faster and clearer when there's a numeric predicate.
+        * fileio.c (report_file_errno): New function, with most of the
+        old contents of report_file_error.
+        (report_file_error): Use it.
+        (Ffile_exists_p, Ffile_accessible_directory_p):
+        Set errno to 0 when it is junk.
+        * fileio.c (Faccess_file):
+        * image.c (x_create_bitmap_from_file):
+        Use faccessat rather than opening the file, to avoid the hassle of
+        having a file descriptor open.
+        * lisp.h (report_file_errno): New decl.
+        * lread.c (Flocate_file_internal): File descriptor 0 is valid, too.
+
+        Minor EBADF fixes.
+        * process.c (create_process, wait_reading_process_output) [AIX]:
+        Remove obsolete SIGHUP-related  code, as Emacs no longer disables
+        SIGHUP, so EBADF is no longer acceptable here (it wouldn't work in
+        a multithreaded environment anyway).
+        * sysdep.c (emacs_close): It's not dangerous to invoke emacs_close (-1).
+
+2013-07-12  Andreas Schwab  <schwab@linux-m68k.org>

+        * sysdep.c (POSIX_CLOSE_RESTART, posix_close) [!POSIX_CLOSE_RESTART]:
+        New macro and function, which emulates the POSIX_CLOSE_RESTART macro
+        and posix_close function on current platforms (which all lack them).
+        (emacs_close): Use it.  This should fix the races on GNU/Linux and

+        and it should avoid closing random victim file descriptors on
+        other platforms.

+
+        * eval.c (backtrace_function, backtrace_args): Now EXTERNALLY_VISIBLE.
+        This is for .gdbinit xbacktrace.
+
+        * sysdep.c, term.c, termcap.c, terminal.c: Integer-related minor fixes.

+        * dbusbind.c (XD_DEBUG_MESSAGE): Omit debugging on C89 hosts, since

+        * dispnew.c (add_window_display_history)
+        (add_frame_display_history):
+        * print.c (print_object):

+        (USAGE1, USAGE2, USAGE3): Remove; they were too long for C89.
+        (main): Adjust to usage reorg.
+        * fns.c (syms_of_fns):
+        * profiler.c (syms_of_profiler):

+        * xsettings.c (anonymous enum):
+        Remove trailing comma.
+        * xsettings.c (apply_xft_settings): Use %f, not %lf; %lf is a C99ism.
+        * lisp.h (ENUM_BF): Use unsigned if pedantic.
+        (DEFUN_FUNCTION_INIT): New macro, that falls back on a cast if pre-C99.
+        (DEFUN): Use it.
+        * regex.c (const_re_char): New type, to pacify strict C89.
+        All uses of 'const re_char' replaced to use it.
+        * regex.h (_Restrict_): Rename from __restrict, to avoid clash
+        with glibc when strict C89.  This change is imported from gnulib.
+        All uses changed.
+        (_Restrict_arr_): Rename from __restrict_arr, similarly.
+        * sysdep.c (time_from_jiffies) [!HAVE_LONG_LONG_INT]:
+        Omit GNU_LINUX implementation, since it requires long long.
+        * xterm.c (x_draw_underwave):
+        Do not assume the traditional order of struct's members.
+        (x_term_init): Rewrite to avoid the need for non-constant structure
+        initializers.
+
+        Syntax cleanup, mostly replacing macros with functions.
+`       This removes the need for the syntax_temp hack.
+        * search.c: Include syntax.h after buffer.h, since syntax.h uses BVAR.
+        * syntax.c (SYNTAX_INLINE): New macro.
+        (SYNTAX_FLAGS_COMSTART_FIRST, SYNTAX_FLAGS_COMSTART_SECOND)
+        (SYNTAX_FLAGS_COMEND_FIRST, SYNTAX_FLAGS_COMEND_SECOND)

+        (ST_COMMENT_STYLE, ST_STRING_STYLE, INTERVALS_AT_ONCE):
+        Now constants, not macros.
+        (syntax_temp) [!__GNUC__]: Remove.
+        (SYNTAX_PREFIX): Remove; all uses replaced by syntax_prefix_flag_p.
+        (syntax_prefix_flag_p): Move implementation of SYNTAX_PREFIX here.
+        (SET_RAW_SYNTAX_ENTRY, SET_RAW_SYNTAX_ENTRY_RANGE, SYNTAX_MATCH)
+        (SETUP_SYNTAX_TABLE, SETUP_SYNTAX_TABLE_FOR_OBJECT):
+        Move here from syntax.h; now functions, not macros.  Except for the
+        last function, these are static since only syntax.c uses them.
+        (syntax_multibyte): Rename from SYNTAX_WITH_MULTIBYTE_CHECK.
+        All uses changed.  Now a function, not a macro; use this fact
+        to simplify the code.
+        (scan_lists, scan_sexps_forward): Remove workarounds for ancient
+        compiler bugs; no longer relevant.
+        * syntax.h: Use INLINE_HEADER_BEGIN, INLINE_HEADER_END.
+        (SYNTAX_INLINE): New macro.

+        Make file descriptors close-on-exec when possible (Bug#14803).
+        This simplifies Emacs a bit, since it no longer needs to worry
+        about closing file descriptors by hand in some cases.
+        It also fixes some unlikely races.  Not all such races, as
+        libraries often open files internally without setting
+        close-on-exec, but it's an improvement.

+        * callproc.c (relocate_fd) [!WINDOWSNT]:
+        * emacs.c (main): Use F_DUPFD_CLOEXEC, not plain F_DUPFD.
+        No need to use fcntl (..., F_SETFD, FD_CLOEXEC), since we're
+        now using pipe2.
