* fileio.c (Fexpand_file_name): Avoid calls to strlen if
the length of 'newdir' is known or may be precalculated.
(file_accessible_directory_p): Prefer to pass Lisp_Object,
not 'char *', and so use precalculated length.
(Ffile_accessible_directory_p):
* callproc.c (encode_current_directory, init_callproc):
* charset.c (init_charset):
* lread.c (load_path_check, load_path_default): Adjust users.
* lisp.h (file_accessible_directory_p): Tweak prototype.
lisp/ls-lisp.el (ls-lisp-version-lessp): New function.
(ls-lisp-handle-switches): Use it to implement the -v switch of GNU ls.
(ls-lisp--insert-directory): Mention the -v switch in the doc string.
Fixes: debbugs:18051
lisp/ls-lisp.el (ls-lisp-use-string-collate)
(ls-lisp-UCA-like-collation): New defcustoms.
(ls-lisp-string-lessp): Use them to control sorting by file
names.
etc/NEWS: Mention that ls-lisp uses string-collate-lessp.
Fixes: debbugs:18051
* 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.
* lisp/ibuffer.el: Replace mode-specific quit function with
`quit-window' via `special-mode'.
(ibuffer-mode-map): Use keybindings from special-mode-map instead
of local overrides.
(ibuffer): Don't store previous windows configuration. Let
`quit-window' handle restoring.
(ibuffer-quit): Remove function. Use `quit-window' instead.
(ibuffer-restore-window-config-on-quit): Remove variable.
(ibuffer-prev-window-config): Remove variable.
src/xdisp.c (get_glyph_string_clip_rects): Don't let the width of a
clipping rectangle become negative (i.e. large positive, since
it's an unsigned data type). This can happen in R2L hscrolled
glyph rows, and caused us to draw the cursor glyph on the fringe.
For the details, see
http://lists.gnu.org/archive/html/emacs-devel/2014-08/msg00543.html.
* src/gmalloc.c: Don't include <stdlib.h>. Declare system malloc and
friends before defining hybrid_malloc and friends if HYBRID_MALLOC
is defined. (Bug#18368)
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.
Fixes: debbugs:18361
src/sysdep.c (str_collate) [__STDC_ISO_10646__]: Improve the
wording of the error messages.
(str_collate) [WINDOWSNT]: Signal an error if w32_compare_strings
sets errno.
src/w32proc.c (get_lcid_callback): Accept locale specifications
without the country part, as in "enu" vs "enu_USA".
(w32_compare_strings): Signal an error if a locale was specified,
but couldn't be translated into a valid LCID.
src/fns.c (Fstring_collate_lessp, Fstring_collate_equalp): Doc fix.
src/w32proc.c (w32_compare_strings): Accept additional argument
IGNORE_CASE. Set up the flags for CompareStringW to ignore case
if requested. If w32-collate-ignore-punctuation is non-nil, add
NORM_IGNORESYMBOLS to the flags.
(LINGUISTIC_IGNORECASE): Define if not already defined.
(syms_of_ntproc) <Vw32_collate_ignore_punctuation>: New variable.
src/sysdep.c (str_collate) [WINDOWSNT]: Adapt to the interface
change.
src/w32.h: Adjust prototype of w32_compare_strings.
etc/NEWS: Mention w32-collate-ignore-punctuation.
Fixes: debbugs:18051
description of sort ...

it for sequences. Add an example.
* src/fns.c (Fsort): Use more natural Qsequencep error.
* test/automated/fns-tests.el (fns-tests-sort): Minor style rewrite.

window to other bottom windows. Reuse a bottom window if it
shows the buffer already. Suggested by Juri Linkov
<juri@jurta.org> in discussion of (Bug#18181).
* configure.ac (AC_CHECK_FUNCS): Check for qsort_r.
* src/fns.c (sort_vector, sort_vector_compare): New functions.

`quote'.
(c-lang-const): Avoid unneeded setq.
(c-lang-constants-under-evaluation): Add docstring.
(c-lang--novalue): New constant.
(c-find-assignment-for-mode): Use it instead of c-lang-constants.
(c-get-lang-constant): Same here.
Get the mode's value using `funcall' now that the code is quoted
with `lambda'.
dumping and the system malloc after dumping. (Bug#18222)
* configure.ac (HYBRID_MALLOC): New macro; define to use gmalloc

full implementation on Cygwin. Remove Cygwin-specific code that
is no longer needed.

Redefine as macros expanding to gmalloc, grealloc, etc.
(DUMPED, ALLOCATED_BEFORE_DUMPING) [CYGWIN]: New macros.

* src/sysdep.c (get_current_dir_name) [HYBRID_GET_CURRENT_DIR_NAME]:
Define as macro, expanding to gget_current_dir_name, and define
the latter.
* src/emacs.c (main) [HYBRID_MALLOC]: Don't call memory_warnings() or
malloc_enable_thread(). Don't initialize malloc.

no longer defined on Cygwin).
(refill_memory_reserve) [HYBRID_MALLOC]: Don't declare.
* src/sheap.c (bss_sbrk_buffer_end): New variable.
* src/unexcw.c (__malloc_initialized): Remove variable.

Vmemory_full.

that of the thumb).
* xterm.c (xm_scroll_callback, xaw_jump_callback): In `whole'
return entire range (the scaled size of the scroll bar minus
