* nt/inc/ms-w32.h (POLL_FOR_INPUT): Likewise.
* src/keyboard.c, src/process.c: Do not define POLL_FOR_INPUT here
because it will be defined in generated config.h if needed.
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.
* 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.
src/w32.c (maybe_load_unicows_dll): New function.
src/emacs.c (main) [WINDOWSNT]: Call maybe_load_unicows_dll early
on, to make sure we can convert file names to and from UTF-8 on
Windows 9X. This fixes a failure to start up because Emacs cannot
find term/w32-win.el. Reported by oslsachem <oslsachem@gmail.com>.
src/w32font.c [WINDOWSNT]: Include w32.h.
(w32_load_unicows_or_gdi32): Call maybe_load_unicows_dll, instead
of implementing the same stuff.
Remove now unused g_b_init_is_windows_9x.
src/w32.h (maybe_load_unicows_dll): Add prototype.
nt/runemacs.c (ensure_unicows_dll): Don't tell in the message box
that "emacs -nw" can do without UNICOWS.DLL on Windows 9X. See
w32.c:maybe_load_unicows_dll and its callers for the reason.
configure.ac: Read $srcdir/nt/mingw-cfg.site when $MSYSTEM is
"MINGW64" as well.
nt/inc/ms-w32.h (pthread_sigmask): Undefine if defined, for MinGW64.
src/unexw32.c (_start) [__MINGW64__]: Define to __start.
* mail/unrmail.el (unrmail-mbox-format): Choice is mboxo, not mboxro.
* woman.el (woman-mark-horizontal-position):
Rename from woman-mark-horizonal-position. Use changed.
