+
+        * configure.ac (_setjmp, _longjmp): Check by compiling
+        instead of by guessing.  The guesses were wrong for
+        recent versions of Solaris, such as Solaris 11.
+
+2012-09-03  Paul Eggert  <eggert@cs.ucla.edu>
+
+        * configure.ac (WARN_CFLAGS): Omit -Wjump-misses-init.
+        It generates false alarms in doc.c, regex.c, xdisp.c.  See
+        <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00040.html>.
+
+        Merge from gnulib, incorporating:
+        2012-08-29 stdbool: be more compatible with mixed C/C++ compiles
+        2011-11-30 manywarnings: update the list of "all" warnings
+
+2012-09-02  Jan Djärv  <jan.h.d@swipnet.se>
+
+        * configure.ac (HAVE_GOBJECT): Check for gobject-2.0 (Bug#12332).
+
+2012-09-01  Paul Eggert  <eggert@cs.ucla.edu>
+
+        * configure.ac (_FORTIFY_SOURCE): Define only when optimizing.
+        This ports to glibc 2.15 or later, when configured with
+        --enable-gcc-warnings.  See Eric Blake in
+        <http://lists.gnu.org/archive/html/bug-grep/2012-09/msg00000.html>.
+
+2012-09-01  Daniel Colascione  <dan.colascione@gmail.com>
+
+        * configure.ac: Introduce term_header variable, which holds the
+        value which will become TERM_HEADER in code.  We effect our choice
+        of window system by setting term_header and WINDOW_SYSTEM_OBJ
+        instead of using ad-hoc variables and flags for each window
+        system.
+
+2012-08-26  Paul Eggert  <eggert@cs.ucla.edu>
+
+        * configure.ac (CFLAGS): Prefer -g3 to -g if -g3 works
+        and if the user has not specified CFLAGS.  -g3 simplifies
+        debugging, since it makes macros visible to the debugger.
+
+2012-08-25  Juanma Barranquero  <lekktu@gmail.com>
+
+        * lib/makefile.w32-in ($(BLD)/execinfo.$(O)): Update dependencies.
+
+2012-08-25  Eli Zaretskii  <eliz@gnu.org>
+
+        * lib/makefile.w32-in ($(BLD)/execinfo.$(O), execinfo.h): New targets.
+        (GNULIBOBJS): Add $(BLD)/execinfo.$(O).
+
+2012-08-24  Paul Eggert  <eggert@cs.ucla.edu>
+
+        On assertion failure, print backtrace if available.
+        Merge from gnulib, incorporating:
+        2012-08-24 execinfo: port to FreeBSD
+        2012-08-22 execinfo: new module
+        * lib/gnulib.mk, m4/gnulib-comp.m4: Regenerate.
+        * lib/execinfo.c, lib/execinfo.in.h, m4/execinfo.m4: New files.
+
+2012-08-22  Glenn Morris  <rgm@gnu.org>
+

+        do not create the bin/emacs link.  (Bug#12011)
+
+2012-08-21  Paul Eggert  <eggert@cs.ucla.edu>

+
+2012-08-20  Glenn Morris  <rgm@gnu.org>
+
+        * configure.ac (AC_PROG_LN_S): Test for ln.

+
+MENU-TITLE should be nil (in which case the matches for this
+element are put in the top level of the buffer index) or a
+string (which specifies the title of a submenu into which the
+matches are put).
+REGEXP is a regular expression matching a definition construct
+which is to be displayed in the menu.  REGEXP may also be a
+function, called without arguments.  It is expected to search
+backwards.  It must return true and set `match-data' if it finds
+another element.
+INDEX is an integer specifying which subexpression of REGEXP
+matches the definition's name; this subexpression is displayed as
+the menu item.
+FUNCTION, if present, specifies a function to call when the index
+item is selected by the user.  This function is called with
+arguments consisting of the item name, the buffer position, and
+the ARGUMENTS.
+
+The variable `imenu-case-fold-search' determines whether or not
+the regexp matches are case sensitive, and `imenu-syntax-alist'
+can be used to alter the syntax table for the search.

+2012-08-27  Dmitry Antipov  <dmantipov@yandex.ru>
+
+        Special MEM_TYPE_SPARE to denote reserved memory.
+        * alloc.c (enum mem_type): New memory type.
+        (refill_memory_reserve): Use new type for spare memory.

+        * character.h (char_printable_p): Remove decl of nonexistent function.

+        are all boolean, so make them single-bit bitfields.
+
+        * lisp.h (ASET): Remove attempt to detect side effects.
+        It was meant to be temporary and it often doesn't work,
+        because when IDX has side effects the behavior of IDX==IDX
+        is undefined.  See Stefan Monnier in

+
+        * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
+        as that's faster and simpler than static storage.  Don't bother
+        with the g_main_context_query overhead if g_main_context_pending
+        says no events are pending.
+        (gfds, gfds_size): Remove these static vars.
+        (xgselect_initialize): Remove; no longer needed.
+        All uses and decls removed.
+
+        * emacs.c (fatal_error_signal_hook): Remove.
+        All uses removed.  This leftover from old code was always 0.
+
+        * casefiddle.c, casetab.c, category.c: Use bool for boolean.
+        * casefiddle.c (casify_object, casify_region):

+
+2012-08-25  Eli Zaretskii  <eliz@gnu.org>
+
+        * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
+
+2012-08-25  Paul Eggert  <eggert@cs.ucla.edu>
+
+        On assertion failure, print backtrace if available.
+        * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
+        (die) [ENABLE_CHECKING]: Print a backtrace if available.
+        * Makefile.in (LIB_EXECINFO): New macro.
+        (LIBES): Use it.
+
+        * bytecode.c, callint.c, callproc.c: Use bool for boolean.

+        (getenv_internal, sync_process_alive, call_process_exited):
+        * lisp.h (USE_SAFE_ALLOCA):

+        * lisp.h, process.h: Adjust prototypes to match above changes.
+        * callint.c (Fcall_interactively): Don't assume the mark's

+
+2012-08-24  Paul Eggert  <eggert@cs.ucla.edu>
+
+        * buffer.c, buffer.h: Use bool for boolean.

+        (mmap_enlarge, mmap_set_vars):
+        * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
+        Use bool for booleans, instead of int.
+        * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
+        since the 1-or-0 return value is always ignored anyway.
+        (mmap_initialized_p):
+        * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
+        * buffer.h, lisp.h: Adjust prototypes to match above changes.
+
+2012-08-23  Paul Eggert  <eggert@cs.ucla.edu>
+
+        * bidi.c: Use bool for boolean.
+        This is a bit more readable, and makes the text segment of bidi.o
+        0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
+        Presumably it's faster too.

+
+        * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
+        compile time tests instead of run time tests on systems that do
+        not use them.
+        (FRAME_MAC_P): Remove leftover from deleted code.
+        * frame.c (syms_of_frame): Remove leftover from deleted code.
+
+2012-08-22  Jan Djärv  <jan.h.d@swipnet.se>

+
+        * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
+        Otherwise, the compiler complains about (A?B:C) where B is void
+        and C is Lisp_Object.  This fixes an incompatibility with Sun C 5.12.
+        (fontset_add): Return void, for FONTSET_ADD.
+

+        (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
+        Remove unused local.
+        * alloc.c (PURE_POINTER_P):
+        * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
+        * editfns.c (Fformat):
+        * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
+        (Fdo_auto_save):

+
+        Make recently-introduced setters macros.

+        (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
+        (set_fontset_default, set_fontset_fallback): Rename from their
+        upper-case counterparts, and make them functions rather than macros.
+        This is more consistent with the other recently-introduced setters.
+        These don't need to be inline, since they're local.

+
+2012-08-21  Paul Eggert  <eggert@cs.ucla.edu>
+
+        * lisp.h (vcopy): Use memcpy rather than our own loop.
+        This fixes a performance regression introduced by the recent
+        addition of vcopy.  This means 'vcopy' will need to be modified
+        for a copying collector, but that's OK.  Also, tighten the
+        checking in the assertion.
+

+
+        * w32uniscribe.c (uniscribe_shape): Fix producing gstring
+        components for RTL text (Bug#11860).  Adjust X-OFFSET of each
+        non-base glyph for the width of the base character, according to
+        what x_draw_composite_glyph_string_foreground expects.
+        Generate WADJUST value according to composition_gstring_width's

+        Adjust users.
+
+2012-08-20  Glenn Morris  <rgm@gnu.org>
+
+        * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):

+
+2012-08-20  Eli Zaretskii  <eliz@gnu.org>
+
+        * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
