attempting to enter the critical section to hang. (Bug#25279)
Work around Bug#22884 by rewording comments and strings to avoid ‘(’
at the start of a line unless it starts a function. This change
is a short-term hack; in the longer run we plan to fix cc-mode’s
performance for C files that have ‘(’ at the start of a line in a
comment or string.
This removes the need for GCPRO1 etc. Suggested by Stefan Monnier in:

src/w32.c:
src/w16select.c: Remove inclusion of setjmp.h, as it is now included
by lisp.h. This completes removal of setjmp.h inclusion
erroneously announced in the previous commit.
src/lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
more accurate.
src/image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
not defined as a macro. The latter happens on MS-Windows.
src/w32uniscribe.c (uniscribe_shape): Reverse the sign of
offsets[j].dv, since the y axis of the screen coordinates points
down, while the y axis of the font definition coordinates points
up. This fixes display of Arabic diacritics such as KASRA and
KASRATAN.
src/w32uniscribe.c (uniscribe_shape): Handle correctly the case of
more than one grapheme cluster passed to the shaper: compute the
offset adjustment values separately for each cluster.
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.
