* 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

* INSTALL.REPO: Remove reference to obsolete configure scripts
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).

* 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.

and text area-relative x-coordinates.

for &key args.
* emacs-lisp/eldoc.el (eldoc-argument-case): Obsolete and change default.
(eldoc-function-argstring-format): Remove.
(eldoc-function-argstring): Always return upcase args.
Use help-make-usage.  Don't add parens.
(eldoc-get-fnsym-args-string): Don't obey eldoc-argument-case since
it's too late to do it right (bug#18048).

 lisp/scroll-bar.el (scroll-bar-horizontal-drag-1)
 (scroll-bar-toolkit-horizontal-scroll): When determining the
 paragraph direction, use the buffer of the window designated in
 the event.

 Avoid overwriting the reversed_p flags in the glyph matrices when
 init_iterator or start_display are called.

 src/xdisp.c (init_iterator): Don't initialize the reversed_p flag of
 the glyph row here.
 (tool_bar_height, redisplay_tool_bar, try_window)
 (try_window_reusing_current_matrix, try_window_id)
 (get_overlay_arrow_glyph_row, display_menu_bar): Initialize the
 reversed_p flag of the iterator's glyph row where the glyph row
 is going to be redrawn.

* vc/diff-mode.el (diff-fixup-modifs): Handle empty line in
context of unified diff.

Without this, for example, 'make -j bootstrap' can fail and report
"Opening input file: no such file or directory,
.../lisp/calendar/diary-loaddefs.el ... recipe for target
'calendar/hol-loaddefs.el' failed", where the hol-loaddefs.el rule
got confused because diary-loaddefs.el was being built in parallel.
* Makefile.in ($(CAL_DIR)/diary-loaddefs.el):
Depend on $(CAL_DIR)/cal-loaddefs.el.
($(CAL_DIR)/hol-loaddefs.el): Depend on $(CAL_DIR)/diary-loaddefs.el.

* w32term.c (w32_horizontal_scroll_bar_handle_click): In y part
of emacs_event return length from si.nPage to si.nMax.
* xdisp.c (set_horizontal_scroll_bar): For right-to-left text
interchange start and end of thumb.
* scroll-bar.el (scroll-bar-horizontal-drag-1): Use cdr of
portion-whole for scrolling right-to-left text.

	* lisp/progmodes/compile.el (compilation-error-regexp-alist-alist):
	Add Guile regexpses.

	* etc/compilation.txt (file): Add Guile backtrace example.

	* test/automated/compile-tests.el (compile--test-error-line):
	Grok FILE being nil.  Allows for Guile tests to pass.
	(compile-tests--test-regexps-data): Add Guile tests.

	* progmodes/gud.el (guiler): New function.  Starts the Guile REPL;
	add Guile debugger support for GUD.

(mouse-sel-has-been-enabled, mouse-sel-original-bindings)
(mouse-sel-original-interprogram-cut-function)
(mouse-sel-original-interprogram-paste-function): Remove.
