* 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'.
The DATA_SEG_BITS hack was needed for older 32 bit platforms.
As a result of this change, Emacs won't work on IRIX 6.5 with IRIX
cc, but that platform is so old that SGI itself stopped supporting
it in December 2013. If you still need Emacs on IRIX, please
either compile with GCC and port the undumping code, or run
'./configure --with-wide-int'.
* configure.ac (DATA_SEG_BITS): Remove. All uses removed.
* src/alloc.c (gdb_make_enums_visible): Update to match lisp.h.
* src/lisp.h (GCTYPEBITS): Move definition up, and switch to the
DEFINE_GDB_SYMBOL_START way to define it.
(NONPOINTER_BITS): New macro.
(EMACS_INT): Use it.
[!USE_LSB_TAG && !WIDE_EMACS_INT]: Fail, and suggest reporting
the problem and/or configuring --with-wide-int.
(USE_LSB_TAG): Simplify, based on above changes.
(gdb_DATA_SEG_BITS): Remove. All uses removed.
* src/vm-limit.c (exceeds_lisp_ptr): Remove. All uses removed.
src/unexcoff.c [MSDOS]: Include libc/atexit.h.
(copy_text_and_data): Zero out the atexit chain pointer before
dumping Emacs.
src/termhooks.h (encode_terminal_code): Update prototype.
src/term.c (encode_terminal_code) [DOS_NT]: Make it externally
visible for all DOS_NT ports, not just WINDOWSNT.
(syms_of_term) [!MSDOS]: Don't define 'tty-menu-*' symbols on MSDOS.
src/sysdep.c (emacs_sigaction_init, init_signals): Don't use SIGCHLD
unless it is defined.
(emacs_pipe) [MSDOS]: Redirect to 'pipe'.

the "ifdef subprocesses" part.
(catch_child_signal): Condition by "ifdef subprocesses".
(syms_of_process) <Qinternal_default_process_sentinel>
<Qinternal_default_process_filter>: Condition by "ifdef subprocesses".
src/msdos.h: Add prototypes for new functions.
(EINPROGRESS): Define.
(O_CLOEXEC): Define to zero.
src/msdos.c (check_window_system): Remove unnecessary an
incompatible duplicate function.
(sys_opendir, readlinkat, faccessat, fstatat, unsetenv): New
functions in support of new functionality.
src/menu.c (single_menu_item): Add visual indication of submenu
also for menus on MSDOS frames.
(Fx_popup_menu) [!MSDOS]: Do not call tty_menu_show on MSDOS.
src/lisp.h (CHECK_PROCESS) [!subprocesses]: Do not define
when async subprocesses aren't supported.
src/font.h (FONT_WIDTH) [MSDOS]: MSDOS-specific definition.
src/emacs.c (close_output_streams): Zero out errno before calling
close_stream.
src/dired.c [MSDOS]: Include msdos.h.
src/conf_post.h (opendir) [MSDOS]: Redirect to sys_opendir.
(DATA_START) [MSDOS]: Define.
(SYSTEM_PURESIZE_EXTRA) [MSDOS]: Enlarge by 25K.

Ifdef away for MSDOS.
(record_kill_process) [MSDOS]: Ifdef away the entire body for MSDOS.
(call_process_cleanup) [MSDOS]: Ifdef away portions not relevant
for MSDOS.
(call_process) [MSDOS]: Fix call sequence of dostounix_filename.
Use temporary file template that is compatible with mkostemp.
Move vfork-related portions under #ifndef MSDOS.
(syms_of_callproc): Unify templates of MSDOS and WINDOWSNT.
lisp/term/pc-win.el (x-list-fonts, x-get-selection-value): Provide
doc strings, as required by snarf-documentation.
msdos/sedlisp.inp:
msdos/sedlibmk.inp:

msdos/INSTALL: Update for Emacs 24.4.
msdos/sedadmin.inp: New file.
This patch was inspired by emacs-24 2014-04-09T13:37:49Z!sdl.web@gmail.com, which fixed
a bug due to sloppy library handling in 'configure'.
* configure.ac (LIB_MATH, LIB_PTHREAD, LIBXMU):
Use AC_SEARCH_LIBS instead of AC_CHECK_LIB as per Autoconf manual.
(LIB_MATH, LIB_PTHREAD, HAVE_X11, IMAGEMAGICK_LIBS, GTK_LIBS)
(DBUS_LIBS, LIBXMU, XFT_LIBS, LIBXSM, LIBXML2_LIBS, LIBS_MAIL)
(with_kerberos):
Don't let the library choice infect $LIBS.
(dnet_ntoa, cma_open): Remove obsolete tests.
(emacs_pthread_function): Probe for pthread_kill, not pthread_self,
as that's a bit more selective on GNU/Linux.
(LIBXEXT): Remove.
(touchlock): Test for existence when $LIBS_MAIL is in use.
(AC_CHECK_FUNCS): Use only $LIB_MATH in addition to $LIBS
when testing for typical functions like accept4, lrand48.
(random, rint): Remove obsolete HP-UX 9 A.09.05 test.
This port requires IRIX cc, as I did not have time to get
undump working with the old GCC on the system I had access to,
but that's better than nothing.
* configure.ac (gl_GCC_VERSION_IFELSE): Remove unused macro
that wouldn't have worked anyway, with IRIX cc.
(emacs_cv_clang, emacs_cv_sanitize_address)
(ns_osx_have_104, ns_osx_have_105):
Don't assume '#error' makes the compiler fail,
as this doesn't work with IRIX cc.
(CFLAGS, LIBS): Don't let the GnuTLS results infect later 'configure'
checks. This runs afoul of an IRIX configuration where GnuTLS is
in an optional library that also contains getdelim, and causes
a later 'configure' to incorrectly think getdelim is supported.
* src/alloc.c (TAGGABLE_NULL): New constant,
for porting to hosts with nontrivial DATA_SEG_BITS settings.
(next_vector, set_next_vector): Use it.
* src/conf_post.h (INET6) [IRIX6_5]: Define.
(HAVE_GETADDRINFO) [IRIX6_5]: Undef.
* src/data.c (BITS_PER_ULL): Don't assume ULLONG_MAX is defined.
* src/lisp.h (lisp_h_XPNTR): Don't OR in bits that aren't masked out,
for consistency with how TAGGABLE_NULL is computed.
