Call x_set_menu_resources_from_menu_face before initially popping up
the menu, so the menu doesn't flash when the face settings are
significantly different from the defaults.
(btowc, iswctype, wctype) [_LIBC]: Redefine to __<fun>.
(BIT_ALPHA, BIT_ALNUM, BIT_ASCII, BIT_NONASCII, BIT_GRAPH, BIT_PRINT)
(BIT_UNIBYTE): Remove.
(re_match_2_internal): Delete corresponding code and streamline the
BIT_MULTIBYTE case to not bother checking ISUNIBYTE.
(CHAR_CLASS_MAX_LENGTH) [!WIDE_CHAR_SUPPORT]: Set to 9 rather than 6.
(re_wctype_t): New type.
(re_wctype, re_iswctype, re_wctype_to_bit): New functions.
(regex_compile): Use them and fix handling of overly long char classes.
-D_ANONYMOUS_STRUCT on compile line.
(EMACS_EXTRA_C_FLAGS): No need for -DORDINARY_LINK.
(ARCH_CFLAGS): Change optimization flags to -O2.
(FOREACH, FORVAR, FORDO, ENDFOR): New definitions.
(ARGQUOTE, DQUOTE): New defines.
New extern declaration.
(make_shadow_gcs) [emacs]:
Use x_alloc_lighter_color_for_widget to do shadow calculation.
(make_shadow_gcs):
Remove code that tests whether the top shadow is dimmer than the bottom
shadow--it shouldn't ever happen.
(display_mode_lines): Return number of mode lines displayed.
(echo_area_display): Use redisplay_mode_lines to draw garbaged
mode lines. Don't temporarily bind redisplay-dont-pause to t.
(struct re_pattern_buffer): Remove newline_anchor.
* regex.c: Keep namespace clean for GNU libc by renaming <fun>
to __<fun> and using `weak_alias (__<fun>, <fun>)'.
(re_max_failures, fail_stack): Use size_t rather than unsigned.
(regex_compile): For ^ and $, choose between buffer and line (beg|end)
depending on the new RE_NO_NEWLINE_ANCHOR syntax flag.
(print_compiled_pattern, re_search_2, mutually_exclusive_p)
(re_match_2_internal, re_compile_pattern, re_comp, regcomp):
Get rid of references to newline_anchor.
(regcomp): Allocate and precompute a fastmap.
