* configure.ac (doc/man/emacs.1): Generate it.
* Makefile.in (top_bootclean): Remove doc/man/emacs.1.
* make-dist: Do not distribute doc/man/emacs.1.
* admin/admin.el (set-version): No need to update doc/man/emacs.1.
* doc/man/emacs.1.in: Rename from emacs.1.
* .bzrignore: Add doc/man/emacs.1.
* Makefile.in (epaths-force-w32): Simplify, assuming that the shell is
bash (as is the case in MSYS).
(msys_w32prefix_subst, msys_sed_sh_escape): Remove (no longer used).
* build-aux/msys-to-w32: simplify the initial over-engineered
interface, and the implementation.
* Makefile.in (epaths-force-w32): Update for the above.
admin: Changes in several documents.
autogen.sh: Neutralize language specific to a repository type.
doc/misc/efaq-w32.texi: Neutralized language specific to a repository type.
doc/misc/gnus-coding.txt: Neutralized language specific to a repository type.
lisp/Makefile.in: Change some production names so they're neutral
about the repository type.
* Makefile.in (AWK, srcdir_doc_info_dir_inputs, info_dir_inputs):
New macros.
(clean): Remove info-dir.*.
(info_dir_deps): Depend on make-info-dir too.
Fix bug with wildcards that weren't expanded.
(${srcdir}/info/dir): Make sure info directory exists.
Don't call pwd; just redirect make-info-dir's stdout to temp file.
* build-aux/make-info-dir: Send output to stdout.
Take input file names from args.
Fix a "FIXME inefficient looping" by using awk's associative arrays.
Basically, this rewrites the script from scratch, and speeds up
'make info/dir' from 2.6s to 0.07s on my platform.
Do all putenv calls before Emacs creates any threads.
Use a safer way to modify the TZ environment variable in the
presence of multiple threads. For further thread-safety,
prefer localtime_r and gmtime_r to localtime and gmtime,
and prefer struct tm's tm_gmtoff (if available) to calling
both localtime_r and gmtime_r.
* configure.ac (LOCALTIME_CACHE): Remove.
We needn't worry about SunOS 4 any more; Sun dropped support in 2003.
All uses of LOCALTIME_CACHE removed. This simplifies the fix.
(tzalloc): Add check for this function.
* admin/merge-gnulib (GNULIB_MODULES): Add time_r, since Emacs now
calls localtime_r and gmtime_r directly.
* src/dbusbind.c (Fdbus__init_bus): Move xputenv call from here ...
(init_dbusbind): ... to this new function.
* src/emacs.c (main) [HAVE_DBUS]: Call it before creating threads.
* src/xterm.c (x_term_init): Move xputenv call from here ...
(init_xterm): ... to this new function.
* src/emacs.c (main) [USE_GTK]: Call it before creating threads.
* src/editfns.c (HAVE_TM_GMTOFF): Default to false.
(dump_tz_string): New constant.
(init_editfns): Use it. This centralizes the dump_tz stuff.
Call set_time_zone_rule here, so that its xputenv is done
before Emacs goes multithreaded.
(mktime_z) [!HAVE_TZALLOC]: New function, which is typically
thread-safe enough for Emacs.
(format_time_string, Fdecode_time, Fcurrent_time_string)
(Fcurrent_time_zone):
Prefer localtime_r and gmtime_r, which are more thread-safe, to
localtime and gmtime. Remove now-unnecessary calls to block_input.
(tm_gmtoff): New static function.
(Fdecode_time, Fcurrent_time_zone): Use it.
(Fencode_time): Use mktime_z, for better thread-safety.
(set_time_zone_rule): Now static. Rewrite to be mostly thread-safe,
i.e., not quite thread-safe but good enough for Emacs typical usage.
Do not reclaim storage that is in the environment; let it leak.
Always call tzset, since localtime_r does not.
* src/emacs.c (dump_tz, Fdump_emacs) [HAVE_TZSET]: Remove dump_tz stuff.
This is now done in init_editfns.
* src/systime.h (mktime_z, timezone_t, tzalloc, tzfree) [!HAVE_TZALLOC]:
New macros and declarations, for platforms lacking tzalloc & friends.

doc/emacs/emacsver.texi (EMACSVER): Bump to 20.0.50.
* configure.ac (HAVE_STATEMENT_EXPRESSIONS): Remove.
For USE_STACK_LISP_OBJECTS, we always assume __GNUC__.
* lisp.h (union Aligned_Cons) [!GCALIGNED]: Define as such.
(SCOPED_CONS_INITIALIZER): New macro.
(scoped_cons) [USE_STACK_LISP_OBJECTS]: Use it.
(USE_LOCAL_ALLOCA): Remove.
(local_cons, local_list1, local_list2, local_list3, local_list4):
Remove. Stack overflow checking makes them too slow.
(make_local_vector): Likewise. Also we just don't have enough
users for it.
(enum LISP_STRING_OVERHEAD): Remove.
(local_string_init, local_vector_init): Remove prototypes.
(make_local_string, build_local_string): Redesign to target short
compile-time string constants, fall back to regular string allocation
where appropriate.
(lisp_string_size): New function.
(verify_ascii) [ENABLE_CHECKING]: Add prototype.
* alloc.c (local_string_init, local_vector_init): Remove.
(verify_ascii) [ENABLE_CHECKING]: New function.
* buffer.c, charset.c, chartab.c, data.c, editfns.c, emacs.c, fileio.c:
* fns.c, font.c, fontset.c, frame.c, keyboard.c, keymap.c, lread.c:
* menu.c, minibuf.c, process.c, textprop.c, xdisp.c, xfns.c, xfont.c:
* xselect.c, xterm.c: All related users changed.
* configure.ac (HAVE_STRUCT_ATTRIBUTE_ALIGNED)
(HAVE_STATEMENT_EXPRESSIONS): New configure-time checks.
* src/alloc.c (local_string_init, local_vector_init):
New functions, defined if USE_LOCAL_ALLOCATORS.
Mostly, these are moved here from lisp.h, as it's not
clear it's worth making them inline.
* src/lisp.h (USE_STACK_LISP_OBJECTS): Default to false.
(GCALIGNED): Depend on HAVE_STRUCT_ATTRIBUTE_ALIGNED and
USE_STACK_LISP_OBJECTS, not on a laundry list.
(local_string_init, local_vector_init): New decls.
(union Aligned_Cons): New type.
(scoped_cons): Use it. Give up on the char trick, as it's a too
much of a maintenance hassle; if someone wants this speedup
they'll just need to convince their compiler to align properly.
Conversely, use the speedup if struct Lisp_Cons happens to
be aligned even without a directive. Better yet, help it along
by using union Aligned_Cons rather than struct Lisp_Cons.
(pointer_valid_for_lisp_object): Remove. This check is not
necessary, since make_lisp_ptr is already doing it. All uses removed.
(local_vector_init, local_string_init): Move to alloc.c.
(build_local_vector): Remove this awkward macro, replacing with ...
(make_local_vector): New macro, which acts more like a function.
Use statement expressions and use __COUNTER__ to avoid macro
capture. Fall back on functions if these features are not supported.
(build_local_string, make_local_string): Likewise.
2014-09-02 gnulib-common.m4: port to GCC 4.2.1 and Sun Studio 12 C++
2014-09-01 manywarnings: add GCC 4.9 warnings
* m4/gnulib-common.m4, m4/manywarnings.m4: Update from gnulib.
* configure.ac (WERROR_CFLAGS): Don't disable -Wnested-externs.
While we're at it, don't disable -Wlogical-op either.
* src/bytecode.c: Include blockinput.h and keyboard.h rather
than rolling their APIs by hand.
* src/emacs.c: Include regex.h and rely on its and lisp.h's API
rather than rolling them by hand.
* src/lastfile.c: Include lisp.h, to check this file's API.
* src/lisp.h (lisp_eval_depth, my_edata, my_endbss, my_endbss_static):
New decls.
* src/regex.h (re_max_failures): New decl.
* src/unexcw.c, src/unexmacosx.c, src/unexw32.c:
Rely on lisp.h's API rather than rolling it by hand.
* src/vm-limit.c (__after_morecore_hook, __morecore, real_morecore):
Declare at top level, to pacify GCC -Wnested-externs.
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.
