This doesn't fix Bug#17598, but it does fix a regression since Emacs
built with xlc until recently, and perhaps it'll help us fix Bug#17598.
* configure.ac (GC_SETJMP_WORKS): Define for AIX, too.
Merge from gnulib, incorporating:
2014-05-30 ftoastr: work around compiler bug in IBM xlc 12.1
* lib/ftoastr.c: Update from gnulib.
* src/alloc.c (gdb_make_enums_visible): Remove FLOAT_TO_STRING_BUFSIZE.
* src/conf_post.h (FLEXIBLE_ARRAY_MEMBER) [__IBMC__]: Don't define to empty.
* src/lisp.h (FLOAT_TO_STRING_BUFSIZE): Make it a macro, instead of an enum,
to work around a compiler bug in IBM xlc 12.1.

 src/xterm.c (x_update_window_end): Don't invalidate the entire
 mouse-highlight info, just signal frame_up_to_date_hook that mouse
 highlight needs to be redisplayed.

Without them, GDB doesn't work to debug Emacs, since the AIX linker
optimizes away the relevant external symbols.  Use enums instead;
this suffices for the AIX port, which is 32-bit-only anyway.
* lisp.h (ENUMABLE, DEFINE_GDB_SYMBOL_ENUM): New macros.
(ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Use them.
(ARRAY_MARK_FLAG_val, PSEUDOVECTOR_FLAG_val, VALMASK_val):
New macros.

* admin/unidata/IVD_Sequences.txt: New file.
* admin/unidata/Makefile.in (${top_srcdir}/src/macuvs.h): New rule.
(all): Build it.
(extraclean): Remove it.
* admin/unidata/README: Mention BidiMirroring.txt and IVD_Sequences.txt.
* admin/unidata/copyright.html: Update to current version from Unicode
Consortium.
* admin/unidata/uvs.el: Rename from admin/mac/uvs.el.
(uvs-print-table-ivd): Output a header in the form that
unidata-gen.el generates.
* lisp/international/README: Refer to the Unicode Terms of Use rather
than copying it bodily here, as that simplifies maintenance.
* src/Makefile.in ($(srcdir)/macuvs.h): New rule.
* src/macuvs.h: Use automatically-generated header.

 src/xdisp.c (move_it_in_display_line_to): Don't record wrap position
 if we are iterating over an object that generates glyphs for
 marginal areas.

 src/xdisp.c (safe__call): Accept va_list argument instead of '...'.
 (safe_call, safe__call1): Construct a va_list argument for safe_call.
 (safe_call1): Call safe_call instead of safe__call directly.

Fixes: debbugs:17577

* src/w32term.c (x_delete_display) [CYGWIN]: Don't free
dpyinfo->w32_id_name, to make sure it doesn't get freed more than
once.

(safe__call, safe__call1, safe__eval): New functions.
(safe_call): Use it.
(prepare_menu_bars): Use it for pre-redisplay-function.
(display_mode_element): Same for `:eval'.

Fixes: debbugs:17577

* configure.ac (opsys): On Power Architecture, treat release 7 of
AIX like releases 5 and 6.
* src/unexaix.c (copy_text_and_data): Don't add text_scnptr to ptr
twice.  _text already includes this offset.
(unrelocate_symbols): Don't cast 64-bit integer to pointer.

Fixes: debbugs:17540

 src/xdisp.c (move_it_in_display_line_to): Avoid infinite recursion:
 when closest_pos is identical to to_charpos, don't recurse, since
 we already tried that, and failed.

 src/w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: If we are
 unwinding when frame's faces were not initialized yet, increment
 the frame's image-cache reference count before calling
 x_free_frame_resources.  Don't dereference
 dpyinfo->terminal->image_cache if it is NULL.

instead of deprecated g_settings_list_schemas if possible.

	* minibuf.c (read_minibuf): Initialize histval to Qnil if unbound.
	Move the initialization up to prevent any "value void" message.

  * w32fns.c (Fx_show_tip): Add SWP_NOOWNERZORDER flag to
  SetWindowPos invocations.

Fixes: debbugs:17398

They fix only bugs that aren't being reported, so it may be better
to do them on the trunk.
* configure.ac (PNG_CFLAGS): Remove.  All uses removed.
(LIBPNG): Don't be consistent about -lpng16 versus -lpng.
Ignore libpng-config's exit status.  Always append -lz -lm.
* src/Makefile.in (PNG_CFLAGS): Remove; all uses removed.
* src/image.c [HAVE_LIBPNG_PNG_H]: Include <libpng/png.h>, not <png.h>.

Fixes: debbugs:17339

* lib-src/emacsclient.c (WCONTINUED): Move to ../src/syswait.h.
* src/process.c (handle_child_signal): Remove WCONTINUED ifdef,
because WCONTINUED is always defined now.
* src/syswait.h (WCONTINUED): Move here from ../lib-src/emacsclient.c.

Fixes: debbugs:15110 debbugs:17339

 src/buffer.c (overlay_strings): Fix the wording of the commentary.

 lisp/mail/rmailsum.el (rmail-new-summary-1): Fix a typo in a comment.

* configure.ac (edit_cflags): Move this up and to the top level,
so that PNG_CFLAGS can use it too.
(PNG_CFLAGS): New var.
(png_longjmp): Use PNG_CFLAGS when checking.
(LIBPNG): Be consistent about -lpng16 etc; e.g., don't use -lpng16
in some places and -lpng in others.  Test libpng-config's exit
status.  If it succeeds, use its output rather than appending -lz -lm.
* src/Makefile.in (PNG_CFLAGS): New var.
(ALL_CFLAGS): Use it.
* src/image.c [HAVE_PNG]: Don't worry about <libpng/png.h>, as
CFLAGS now handles this.

GCC 4.9.0 warned about this, and I couldn't easily prove to my own
satisfaction that they would always be initialized.

 src/term.c (tty_menu_display): Move the cursor to the active menu
 item.
 (tty_menu_activate): Return the cursor to the active menu item
 after displaying the menu and after displaying help-echo.  See
 http://lists.gnu.org/archive/html/emacs-devel/2014-04/msg00402.html
 for the details of why this is needed by screen readers and
 Braille displays.

Fixes: debbugs:15110

 src/search.c (Fnewline_cache_check): Don't try to count newlines
 outside the buffer's restriction, as find_newline doesn't support
 that.

All uses removed.
(jpeg_load_body) [lint]: Add a 'volatile' to pacify a buggy GCC in
a way that also works with GCC 4.9.0.

 glyph is written to TEXT_AREA of the temporary glyph_row.

 buffer and the selected window's buffer are one and the same.
