See the interminable bug discussion if you have nothing better to do.

Fixes: debbugs:18051

 src/syntax.c (scan_lists): Don't examine positions before BEGV.

* configure.ac (newlocale): Check for this, not for uselocale.
* src/sysdep.c (LC_COLLATE, LC_COLLATE_MASK, freelocale, locale_t)
(newlocale, wcscoll_l): Define substitutes for platforms that
lack them, so as to simplify the mainline code.
(str_collate): Simplify the code by assuming the above definitions.
Use wcscoll_l, not uselocale, as uselocale is too fragile.  For
example, the old version left the Emacs in the wrong locale if
wcscoll reported an error.  Use 'int', not ptrdiff_t, for the int
result.  Report an error if newlocale fails.

Fixes: debbugs:18051

* sysdep.c (str_collate): Return int.
(str_collate) [__STDC_ISO_10646__]: Propagate error of wcscoll.

Vinternal__top_level_message, as suggested by Stefan Monnier in
http://lists.gnu.org/archive/html/emacs-devel/2014-08/msg00493.html
All related users changed.
* lisp/startup.el (normal-top-level): Now use internal--top-level-message.
* doc/lispref/eval.texi (Eval): Mention possible recovery from stack overflow.

* sysdep.c (stack_direction): Replace stack_grows_down
to simplify calculation of stack boundaries.
(handle_sigsegv): Check whether we really crash somewhere near
to stack boundary, and handle fatal signal as usual if not.
(init_sigsegv): Adjust accordingly.

gnus-art.el (gnus-article-browse-html-save-cid-content, gnus-article-browse-html-parts): Revert last change that breaks links other than cid contents

gnus-art.el (gnus-article-browse-html-save-cid-content, gnus-article-browse-html-parts): Make cid file names relative

* admin/authors.el (authors-ignored-files, authors-valid-file-names)
(authors-renamed-files-alist): Additions.
(authors-renamed-files-alist): Revert 2014-08-09 change.
(authors): Sort authors in utf-8 order.

Fixes: debbugs:2263

support.  Unconditionally check for sigsetjmp and siglongjmp.
(HAVE_STACK_OVERFLOW_HANDLING): Define if we can support it.
* src/lisp.h (toplevel) [HAVE_STACK_OVERFLOW_HANDLING]: Declare
siglongjmp point to transfer control from SIGSEGV handler.
* src/keyboard.c (return_to_command_loop, recover_top_level_message)
[HAVE_STACK_OVERFLOW_HANDLING]: New variables.
(regular_top_level_message): New variable.
(command_loop) [HAVE_STACK_OVERFLOW_HANDLING]: Handle non-local
exit from SIGSEGV handler and adjust message displayed by Vtop_level
if appropriate.
(syms_of_keyboard): DEFVAR Vtop_level_message and initialize
new variables described above.
* src/sysdep.c [HAVE_SYS_RESOURCE_H]: Include sys/resource.h as such.

* src/emacs.c (main): Remove use of obsolete macro
G_SLICE_ALWAYS_MALLOC.

* net/shr.el (shr-copy-url): Encode copied URL to avoid getting
URLs containing spaces and the like.

 src/w32proc.c (get_lcid_callback, get_lcid, w32_compare_strings):
 New functions.
 src/w32.h (w32_compare_strings): Add prototype.
 src/w32.c <g_b_init_compare_string_w>: New global flag.
 (globals_of_w32): Initialize it.
 src/sysdep.c (str_collate) [WINDOWSNT]: Implementation for MS-Windows.
 src/fns.c (Fstring_collate_lessp, Fstring_collate_equalp)
 [WINDOWSNT]: Call str_collate on MS-Windows.

 etc/NEWS: Mention that string-collate-* functions are supported on
 MS-Windows as well.

* font.h (struct font_driver): Convert text_extents to
return void because returned value is never actually used.
* macfont.c (macfont_text_extents):
* w32font.c (w32font_text_extents):
* xftfont.c (xftfont_text_extents): Adjust to return void
and assume that 'metrics' argument is always non-NULL.
* ftfont.c (ftfont_text_extents):
* xfont.c (xfont_text_extents): Likewise.  Avoid redundant memset.

* fns.c (str_collate): Move decl from here ...
* lisp.h (str_collate): ... to here.
* sysdep.c (str_collate): Prune away some of the forest of ifdefs.
Remove unnecessary casts.  Use SAFE_NALLOCA to avoid
potential problems with integer overflow.  Don't assume
setlocale succeeds.  Remove unnecessary test before restoring
locale via setlocale, and free the copied setlocale string
when done with it.

Fixes: debbugs:18051

* lisp/subr.el (remq): Fix docstring.

Fixes: debbugs:18253

Fixes: debbugs:18320

on non-Posix platforms.

Fixes: debbugs:18323

cc-engine.el (c-forward-type): Enhance to recognise and return 'decltype.
(c-forward-decl-or-cast-1): New let variables backup-kwd-sym,
prev-kwd-sym, new-style-auto.  Enhance to handle the new "auto" keyword.
    
cc-fonts.el (c-font-lock-declarations): Handle the "decltype" keyword.
(c-font-lock-c++-new): Handle "decltype" constructions.
    
cc-langs.el (c-auto-ops, c-auto-ops-re): New c-lang-defconsts/defvars.
(c-haskell-op, c-haskell-op-re): New c-lang-defconsts/defvars.
(c-typeof-kwds, c-typeof-key): New c-lang-defconsts/defvars.
(c-typeless-decl-kwds): Append "auto" onto the C++ value.
(c-not-decl-init-keywords): Also exclude c-typeof-kwds from value.

cc-langs.el (c->-op-cont-tokens): New lang-const split off from
c->-op-cont-re.
(c->-op-cont-tokens): Change to use the above.
(c->-op-without->-cont-regexp): New lang-const.
    
cc-engine.el (c-forward-<>-arglist-recur): Use
c->-op-without->-cont-regexp in place of c->-op-cont-tokens.

* configure.ac: Check also for the uselocale function. 

* src/fns.c (Fstring_collate_lessp, Fstring_collate_equalp): New DEFUNs.

* src/sysdep.c (str_collate): New function.  (Bug#18051)

#18306.  The bug was introduced on 2014-08-02.

 configure.ac: Accept "*-mingw*", not just "*-mingw32", as
 canonical name of a MinGW build, because using MSYS2 'uname'
 produces "MINGW64".

 src/Makefile.in (emacs$(EXEEXT)): Retry deletion of bootstrap-emacs
 if the initial "rm -f" fails.  This is for MinGW builds, where
 MS-Windows will not allow deleting the executable file of a
 running program.

lisp/gnus/mm-view.el (mm-display-inline-fontify): Make the working buffer temporarily displayed when running a mode function (at least org-mode requires it)

 lisp/textmodes/texnfo-upd.el (texinfo-specific-section-type): Don't
 recognize a Top node if there are other sectioning commands
 earlier in the Texinfo file.  This fixes a bug in
 texinfo-make-menu and avoids inflooping in
 texinfo-all-menus-update when they are invoked on texinfo.texi.

* window.el (window--side-window-p): New function.
(split-window, window-splittable-p): Use window--side-window-p to
determine whether WINDOW can be split (Bug#18304).
* calendar/calendar.el (calendar-basic-setup): Fix one call of
`window-splittable-p' and add another (Bug#18304).

Ref: http://lists.gnu.org/archive/html/emacs-devel/2014-01/msg01038.html

* lisp/progmodes/python.el (python-new-pythonpath): Extract from
`python-shell-calculate-process-environment'.

 src/w32term.c (w32_scroll_bar_handle_click)
 (w32_horizontal_scroll_bar_handle_click)
 (x_scroll_bar_report_motion)
 (x_horizontal_scroll_bar_report_motion): For SB_THUMBPOSITION and
 SB_THUMBTRACK, use the 32-bit position information returned by
 GetScrollInfo, not the 16-bit information returned in the Windows
 message sent to us.

 src/w32term.c (w32_horizontal_scroll_bar_handle_click): Fix the
 second coordinate ('y') reported for dragging the horizontal
 scroll bar thumb.
