It's not safe to call qsort or qsort_r, since they have undefined
behavior if the user-specified predicate is not a total order.
Also, watch out for garbage-collection while sorting vectors.
* admin/merge-gnulib (GNULIB_MODULES): Add vla.
* configure.ac (qsort_r): Remove, as we no longer use qsort-like
functions.
* lib/gnulib.mk, m4/gnulib-comp.m4: Regenerate.
* lib/vla.h, m4/vararrays.m4: New files, copied from gnulib.
* lib/stdlib.in.h, m4/stdlib_h.m4: Sync from gnulib, incorporating:
2014-08-29 qsort_r: new module, for GNU-style qsort_r
The previous two files' changes are boilerplate generated by
admin/merge-gnulib, and should not affect Emacs.
* src/fns.c: Include <vla.h>.
(sort_vector_predicate) [!HAVE_QSORT_R]: Remove.
(sort_vector_compare): Remove, replacing with ....
(inorder, merge_vectors, sort_vector_inplace, sort_vector_copy):
... these new functions.
(sort_vector): Rewrite to use the new functions.
GCPRO locals, since the predicate can invoke the GC.
Since it's in-place return void; caller changed.
(merge): Use 'inorder', for clarity.

* doc/emacs/programs.texi (Program Modes): Don't advertise VMS DCL support
any more.
* doc/misc/ediff.texi (Merging and diff3): Don't mention lack of support
for VMS diff, we no longer support VMS.

about VMS, which we no longer support.

and fix a FIXME, using convert-standard-filename in place of
removed ada-convert-file-name.
* lisp/url/url-handlers.el: Remove a comment about VMS, which we no longer
support.
* admin/merge-gnulib (GNULIB_MODULES): Add binary-io. It was already
present implicitly; this just makes the dependence explicit.
* lib-src/etags.c, lib-src/hexl.c, lib-src/make-docfile.c:
Include binary-io.h instead of fcntl.h and/or io.h.
(main): Use set_binary_mode or SET_BINARY
in place of handcrafted code.
* lib-src/etags.c (main) [DOS_NT]:
* lib-src/movemail.c (main) [WINDOWSNT]:
Don't mess with _fmode.
* lib-src/etags.c (main, process_file_name, analyse_regex):
Use fopen/popen's "b" flag instead.

instead.
* src/callproc.c (create_temp_file): Use mkostemp's O_BINARY flag.
* src/emacs.c [MSDOS]:
* src/emacs.c (main) [DOS_NT]: Don't mess with _fmode.
(main) [MSDOS]: Use SET_BINARY instead of setmode.
* src/minibuf.c: Include binary-io.h instead of fcntl.h.
(read_minibuf_noninteractive):
Use set_binary_mode instead of handcrafted code.
Don't call emacs_set_tty if emacs_get_tty failed.
* src/sysdep.c, src/systty.h (emacs_get_tty): Return int, not void.
* src/sysdep.c (emacs_open, emacs_pipe): Use O_BINARY.
* src/w32.c (pipe2): Adjust eassert to include O_BINARY.
Fixes: debbugs:18006
* admin/unidata/Makefile.in (${top_srcdir}/src/macuvs.h): Make and load .elc.
(.el.elc): Replace with pattern rule.
(%.elc): New.
(unidata.txt): Use $<.
(compile): Remove.
(${DSTDIR}/charprop.el): Use order-only prereqs rather than a sub-make.
* admin/unidata/IVD_Sequences.txt: New file.
* admin/unidata/Makefile.in (${top_srcdir}/src/macuvs.h): New rule.
(all): Build it.
(extraclean): Remove it.

Consortium.

(uvs-print-table-ivd): Output a header in the form that
unidata-gen.el generates.
* lisp/international/README: Refer to the Unicode Terms of Use rather
than copying it bodily here, as that simplifies maintenance.
* src/Makefile.in ($(srcdir)/macuvs.h): New rule.
* src/macuvs.h: Use automatically-generated header.
* INSTALL: Prefer './configure FOO=BAR' to 'FOO=BAR ./configure'.

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'.

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.
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.
