Merge from gnulib, incorporating:
2012-08-24 execinfo: port to FreeBSD
2012-08-22 execinfo: new module
* admin/merge-gnulib (GNULIB_MODULES): Add execinfo.
* lib/gnulib.mk, m4/gnulib-comp.m4: Regenerate.
* lib/execinfo.c, lib/execinfo.in.h, m4/execinfo.m4: New files.
* src/alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
(die) [ENABLE_CHECKING]: Print a backtrace if available.
* src/Makefile.in (LIB_EXECINFO): New macro.
(LIBES): Use it.
This is a bit more readable, and makes the text segment of bidi.o
0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
Presumably it's faster too.
(bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
Now bool.
(bidi_cache_find_level_change, bidi_cache_iterator_state)
(bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
(bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
(bidi_explicit_dir_char, bidi_level_of_next_char)
(bidi_find_other_level_edge, bidi_move_to_visually_next):
Use bool for booleans, instead of int.
* dispextern.h (bidi_init_it, bidi_paragraph_init)
(bidi_unshelve_cache): Adjust decls to match code.
compile time tests instead of run time tests on systems that do
not use them.
(FRAME_MAC_P): Remove leftover from deleted code.
* frame.c (syms_of_frame): Remove leftover from deleted code.
* window.el (display-buffer-in-atom-window, window--major-non-side-window)
(window--major-side-window, display-buffer-in-major-side-window)
(delete-side-window, display-buffer-in-side-window): New
functions.
(window--side-check, window-deletable-p, delete-window)
(delete-other-windows, split-window): Handle side windows and
atomic windows appropriately.
(window--display-buffer): Call display-buffer-record-window also
when the window buffer did not change.
* window.el (walk-window-tree, window-with-parameter): New
optional argument MINIBUF to control whether these functions
should run on the minibuffer window.
(window-at-side-list): Don't operate on minibuffer window.
(window-in-direction): Simplify and rewrite doc-string.
Otherwise, the compiler complains about (A?B:C) where B is void
and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
(fontset_add): Return void, for FONTSET_ADD.
* fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
(set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
(set_fontset_default, set_fontset_fallback): Rename from their
upper-case counterparts, and make them functions rather than macros.
This is more consistent with the other recently-introduced setters.
These don't need to be inline, since they're local.
This fixes a performance regression introduced by the recent
addition of vcopy. This means 'vcopy' will need to be modified
for a copying collector, but that's OK. Also, tighten the
checking in the assertion.
src/w32uniscribe.c (uniscribe_shape): Fix producing gstring
components for RTL text. Adjust X-OFFSET of each non-base glyph
for the width of the base character, according to what
x_draw_composite_glyph_string_foreground expects. Generate
WADJUST value according to composition_gstring_width's
expectations, to produce correct width of the composed character.
Reverse the sign of the DU offset produced by ScriptPlace.
* lisp.h (vcopy): New function to copy data into vector.
* dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
* fns.c (Ffillarray): Use ASET.
* keyboard.c (timer_check_2): Use AREF and ASET.
(append_tool_bar_item, Frecent_keys): Use vcopy.
* lread.c (read_vector): Use ASET.
* msdos.c (Frecent_doskeys): Use vcopy.
* xface.c (Finternal_copy_lisp_face): Use vcopy.
(Finternal_merge_in_global_face): Use ASET and vcopy.
* xfont.c (xfont_list_pattern): Likewise.
* window.c (Fwindow_point): For the selected window always return
the position of its buffer's point.
(Fset_window_point): For the selected window always go in its
buffer to the specified position.
* window.el (window-point-1, set-window-point-1): Remove.
(window-in-direction, record-window-buffer)
(set-window-buffer-start-and-point, split-window-below)
(window--state-get-1, display-buffer-record-window): Replace
calls to window-point-1 and set-window-point-1 by calls to
window-point and set-window-point respectively.
