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.
(bcopy, bcmp, REGEX_REALLOCATE, re_match_2_internal):
Use memcmp and memcpy instead of bcopy and bcmp.
(init_syntax_once): Use ISALNUM.
(PUSH_FAILURE_POINT, re_match_2_internal): Remove failure_id.
(REG_UNSET_VALUE): Remove. Use NULL instead.
(REG_UNSET, re_match_2_internal): Use NULL.
(SET_HIGH_BOUND, MOVE_BUFFER_POINTER, ELSE_EXTEND_BUFFER_HIGH_BOUND):
New macros.
(EXTEND_BUFFER): Use them (to work with BOUNDED_POINTERS).
(GET_UNSIGNED_NUMBER): Don't use ISDIGIT.
(regex_compile): In handle_interval, return an error rather than try to
unfetch the interval if we can't find the closing brace.
Obey the RE_NO_GNU_OPS syntax bit.
(TOLOWER): New macro.
(regcomp): Use it.
(regexec): Allocate regs.start and regs.end as one block.
the update_begin and update_end calls here from update_frame_1.
(update_frame_1): Don't set display_completed here, don't call
update_begin/update_end.
