sigprocmask isn't portable in a multithreaded process.
* configure.ac (gl_THREADLIB): Remove dummy.
Merge from gnulib, incorporating:
2014-05-28 pthread_sigmask, timer-time: use gl_THREADLIB only if needed
* m4/pthread_sigmask.m4, m4/timer_time.m4: Update from gnulib.
* src/Makefile.in (LIB_PTHREAD_SIGMASK): Remove; all uses removed.
Fixes: debbugs:17561
src/Makefile.in (C_HEAP_SWITCH): Get the predefined heap size from
configure.
(ADDSECTION, MINGW_TEMACS_POST_LINK): Remove, no longer used.
src/lisp.h (NONPOINTER_BITS): Modify the condition to define to zero
for MinGW, since it no longer uses gmalloc.
src/buffer.c: Do not define mmap allocations functions for Windows.
Remove mmap_find which is unused. Remove mmap_set_vars which does
nothing useful.
[WINDOWSNT]: Include w32heap.h.
(init_buffer): Always allocate new memory for buffers.
src/emacs.c: Remove mmap_set_vars calls.
src/image.c (free_image): Undef free for Windows because it is
redirected to our private version.
src/unexw32.c (COPY_PROC_CHUNK): Use %p format for 64bits
compatibility.
(copy_executable_and_dump_data): Remove dumping the heap section.
(unexec): Restore using_dynamic_heap after dumping.
src/w32heap.c (dumped_data_commit, malloc_after_dump)
(malloc_before_dump, realloc_after_dump, realloc_before_dump)
(free_after_dump, free_before_dump, mmap_alloc, mmap_realloc)
(mmap_free): New functions.
src/w32heap.h: Declare dumped_data and mmap_* function prototypes.
nt/inc/ms-w32.h: Switch to the system heap allocation scheme
instead of GNU malloc and ralloc.
nt/inc/sys/mman.h: New file.
nt/INSTALL: Update for the new build requirements.
etc/NEWS: Mention build changes on MS-Windows.
configure.ac (C_HEAP_SWITCH) define for different values of
dumped heap size depending on 32/64bits arch on Windows.
Don't check for pthreads.h on MinGW32/64, it gets in the way.
Use mmap(2) for buffers and system malloc for MinGW32/64.
* configure.ac (opsys): On Power Architecture, treat release 7 of
AIX like releases 5 and 6.
* src/unexaix.c (copy_text_and_data): Don't add text_scnptr to ptr
twice. _text already includes this offset.
(unrelocate_symbols): Don't cast 64-bit integer to pointer.
Fixes: debbugs:17540
Also, remove update-game-scores's limits on game scores and
simplify its file-locking code.
* configure.ac (getdelim, getline): Remove.
* lib-src/update-game-score.c (struct score_entry): Unify the username and
data members to a single user_data member, since they don't need to be
changed independently and getdelim and getline aren't helpful.
Make the score member char *, not intmax_t, so that scores are not
limited to intmax_t. All uses changed.
(lose_syserr): A zero errno stands for invalid data in score file.
(normalize_integer): New function.
(main): Use it. Check for invalid scores. Omit redundant stat check.
(read_score): First arg is now a string, not a FILE *. All uses
changed. Do not use getdelim or getline; that's way simpler.
(read_scores): Read the whole file, and let read_score handle each
line.
(score_compare): Compare strings representing integers, not integers.
(write_scores) [DOS_NT]: Eliminate unnecessary chmod.
(lock_file): Simplify locking code, eliminating goto.
Check for unlink failure.
* .bzrignore: Remove lib-src/ctags.c.
* lib-src/Makefile.in (etags_args): Remove, replacing with ...
(etags_cflags, etags_libs): New macros. All uses changed.
(ctags${EXEEXT}): Don't compile etags.c, as compiling etags.c in
parallel (once for ctags, once for etags) breaks parallel makes
with compilers that use the source file name to name temporaries,
such as Sun C 5.12. Instead, compile ctags.c.
* lib-src/ctags.c: New file.
* configure.ac (HAVE_PNG): Port to platforms where libpng-config
succeeds but png.h is absent, by testing libpng-config's output
rather than trusting it. I ran into this problem when building
Emacs trunk on a Solaris 10 host.
* INSTALL: Prefer './configure FOO=BAR' to 'FOO=BAR ./configure'.
* INSTALL.REPO: pkg-config is no longer required to build from
the repository.
* autogen.sh: Don't check for pkg-config.
(progs): Remove pkg-config.
(pkg_config_min, AUTORECONF_ENV, env_space, ACLOCAL_PATH):
Remove. All uses removed.
* m4/pkg.m4: New file, built by admin/merge-pkg-config.
* configure.ac: Remove unnecessary m4_pattern_forbid of ^PKG_ and
an AC_ARG_VAR of PKG_CONFIG_PATH. pkg.m4 does that for us.
(EMACS_CHECK_MODULES): Remove workaround for old pkg-config bug,
as we use pkg.m4 from a newer pkg-config.
* admin/merge-pkg-config: New script.
* admin/notes/copyright: Update for m4/*.m4, in particular m4/pkg.m4.
* etc/NEWS: Prefer './configure FOO=BAR' to 'FOO=BAR ./configure'.
* etc/PROBLEMS (Build-time-problems): Remove pkg-config problem
that is no longer an issue.
* nt/INSTALL: Remove no-longer-needed notes about pkg-config.
* configure.ac (HAVE_XFIXES): Define if available.
(XFIXES_CFLAGS, XFIXES_LIBS): New AC_SUBSTs.
* src/Makefile.in (XFIXES_CFLAGS, XFIXES_LIBS): New var.
* src/xfns.c (x_set_mouse_color): Do not call make_invisible_cursor here.
(make_invisible_cursor): Move to...
* src/xterm.c (make_invisible_cursor): ...here.
(x_probe_xfixes_extension, xfixes_toggle_visible_pointer)
(x_toggle_visible_pointer, x_setup_pointer_blanking): New functions.
(x_term_init): Call to x_setup_pointer_blanking.
(XTtoggle_invisible_pointer): Use blanking specific to this display.
* src/xterm.h (struct x_display_info): New member toggle_visible_pointer.
* configure.ac (EMACS_CHECK_MODULES): Check for failed exit status
of pkg-config, on older pkg-config versions that don't do it
properly.
Fixes: debbugs:17438
Earlier versions are buggy, as pkg-config --libs can output
nothing, which causes xrandr link failures.
* configure.ac (PKG_PROG_PKG_CONFIG): Bump from 0.9.0 to 0.26.
Fixes: debbugs:17438
This is mainly for simplicity, but it should also avoid
some future problems like the ones we recently had with NetBSD.
* configure.ac (LIBPNG): Configure after LIBZ. Use libpng-config
for cflags, too. Append -lz if we're not already doing that with
LIBZ. Do not bother appending -lm, since we always append that.
Coalesce some duplicate code.
* src/Makefile.in (PNG_CFLAGS): New var.
(ALL_CFLAGS): Use it.
* src/image.c [HAVE_PNG]: Don't worry about <libpng/png.h>, as
CFLAGS now handles this.
Fixes: debbugs:17339
They fix only bugs that aren't being reported, so it may be better
to do them on the trunk.
* configure.ac (PNG_CFLAGS): Remove. All uses removed.
(LIBPNG): Don't be consistent about -lpng16 versus -lpng.
Ignore libpng-config's exit status. Always append -lz -lm.
* src/Makefile.in (PNG_CFLAGS): Remove; all uses removed.
* src/image.c [HAVE_LIBPNG_PNG_H]: Include <libpng/png.h>, not <png.h>.
Fixes: debbugs:17339
* configure.ac (IMAGEMAGICK_MODULE): Bump prereq from 6.2.8 to 6.3.5.
A more-complicated fix would be to remove uses of PixelSetMagickColor,
introduced in ImageMagick 6.3.5 (Sept. 2007).
Fixes: debbugs:17339
Preserve ACLOCAL_PATH in later builds, so that by default it has
the same value as it did in the first build after initial checkout.
* Makefile.in (ACLOCAL_PATH): New macro.
($(srcdir)/aclocal.m4): Use it.
* configure.ac (ACLOCAL_PATH): AC_SUBST it.
* autogen.sh (env_space): New var.
Tell user what variables, if any, to pass to 'configure'.
The recent changes to configure.ac removed the transliteration of
-I to -isystem in CFLAGS, which is needed for --enable-gcc-warnings.
Bring this back while keeping the spirit of the recent changes.
* configure.ac (edit_cflags): Restore this shell var, and put it
at the top level, where it'll be useful when emacs-24 is next merged.
(EMACS_CHECK_MODULES): New macro. All uses of PKG_CHECK_MODULES
changed to use it.
* autogen.sh (ACLOCAL_PATH, AUTORECONF_ENV): New vars.
Set them to avoid problems when maintainers prepend their own
Automake installations to their PATH. Report an error if pkg.m4
can't be found.
* configure.ac: Use pkg-config's pkg.m4, rather than reinventing it.
Add explicit AC_SUBST's where needed.
* autogen.sh (progs): Add pkg-config.
(pkg_config_min): New variable.
* INSTALL.REPO: Mention pkg-config.
* etc/PROBLEMS: Mention a related issue that can occur with a local automake.
* configure.ac (edit_cflags): Move this up and to the top level,
so that PNG_CFLAGS can use it too.
(PNG_CFLAGS): New var.
(png_longjmp): Use PNG_CFLAGS when checking.
(LIBPNG): Be consistent about -lpng16 etc; e.g., don't use -lpng16
in some places and -lpng in others. Test libpng-config's exit
status. If it succeeds, use its output rather than appending -lz -lm.
* src/Makefile.in (PNG_CFLAGS): New var.
(ALL_CFLAGS): Use it.
* src/image.c [HAVE_PNG]: Don't worry about <libpng/png.h>, as
CFLAGS now handles this.
Fixes: debbugs:17339
(ORDINARY_GOALS): New macro, which excludes 'bootstrap'.
(bootstrap, .PHONY): New rules.
* INSTALL.REPO: Document current procedure better.
Move copyright notice to just before license notice.
All uses removed. This hack is no longer needed here
now that we can assume GNU Make's .PHONY feature works.
(bootstrap): No need to make 'info', since 'all' now implies 'info'.
