This doesn't fix Bug#17598, but it does fix a regression since Emacs
built with xlc until recently, and perhaps it'll help us fix Bug#17598.
* configure.ac (GC_SETJMP_WORKS): Define for AIX, too.
Merge from gnulib, incorporating:
2014-05-30 ftoastr: work around compiler bug in IBM xlc 12.1
* lib/ftoastr.c: Update from gnulib.
* src/alloc.c (gdb_make_enums_visible): Remove FLOAT_TO_STRING_BUFSIZE.
* src/conf_post.h (FLEXIBLE_ARRAY_MEMBER) [__IBMC__]: Don't define to empty.
* src/lisp.h (FLOAT_TO_STRING_BUFSIZE): Make it a macro, instead of an enum,
to work around a compiler bug in IBM xlc 12.1.
* 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
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
* 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
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.
Fixes: debbugs:9684
* configure.ac: Fix a bug in shell pattern matching that caused
'configure' to treat Solaris 2.5.1 as if it were Solaris 10 or later.
Fixes: debbugs:16896
* configure.ac (difftime): Remove.
* lib/update-game-score.c (difftime) [!HAVE_DIFFTIME]: Remove.
(read_score) [HAVE_GETDELIM]: Don't access uninitialized storage.
(read_scores, write_scores): Check for fclose failure.
(write_scores): Use fchmod, not chmod, to avoid a race.
(lock_file): Fix test for out-of-date lock file; it was reversed.
Use ordinary subtraction rather than difftime; since we're already
assuming POSIX we don't need to worry about the possibility of
time_t being a magic cookie.
configure.ac: Read $srcdir/nt/mingw-cfg.site when $MSYSTEM is
"MINGW64" as well.
nt/inc/ms-w32.h (pthread_sigmask): Undefine if defined, for MinGW64.
src/unexw32.c (_start) [__MINGW64__]: Define to __start.
Problem and proposed patch reported by Ulrich Mueller;
this patch uses a somewhat-different approach.
* configure.ac (SETFATTR): New variable.
* src/Makefile.in (SETFATTR): New macro.
(temacs$(EXEEXT)): Use it.
configure.ac (canonical, C_SWITCH_SYSTEM): Support a 64-bit
MinGW64 build on MS-Windows.
nt/inc/ms-w32.h (sys_kill): Fix prototype.
src/w32term.c (w32_initialize): Use LCID and LOWORD.
src/w32proc.c (create_child): Use pid_t for 5th argument.
(IsValidLocale): Don't provide prototype for MinGW64.
(Fw32_get_valid_keyboard_layouts, Fw32_get_keyboard_layout)
(Fw32_set_keyboard_layout): Use HKL and HIWORD/LOWORD.
src/w32heap.c (allocate_heap) [_WIN64]: Use "ull", not "i64", which
MinGW64 doesn't support.
src/lisp.h (EMACS_INT) [_WIN64]: Define for the MinGW64 build.
* configure.ac (xcsdkdir): Default to empty.
(XCRUN): Don't require Darwin for xcrun. Move xcrun checking to
just before AM_INIT_AUTOMAKE, to make the dependency between it
and automake clearer.
(CC): Don't use AC_PROG_CC twice; only the first use expands to the
shell code that is wanted, which breaks 'configure' on non-Darwin
platforms. Instead, fix CC by hand if it's not found.
On my Fedora 19 platform the core dumps were so big that
my desktop became nearly catatonic.
* configure.ac: Check whether addresses are sanitized.
(CANNOT_DUMP): Warn if addresses are sanitized and not CANNOT_DUMP.
(DOUG_LEA_MALLOC): Do not define if addresses are sanitized.
(SYSTEM_MALLOC): Define if addresses are sanitized.
* src/alloc.c (no_sanitize_memcpy) [MAX_SAVE_STACK > 0]: New function.
(Fgarbage_collect) [MAX_SAVE_STACK > 0]: Use it.
(USE_ALIGNED_MALLOC): Do not define if addresses are sanitized.
(mark_memory): Use ATTRIBUTE_NO_SANITIZE_ADDRESS rather than
a clang-only syntax.
* src/conf_post.h (__has_feature): New macro, if not already defined.
(ADDRESS_SANITIZER, ADDRESS_SANITIZER_WORKAROUND)
(ATTRIBUTE_NO_SANITIZE_ADDRESS): New macros.
