Fixes: debbugs:11603

Restore deprecation warnings, except for older libpng.

2012-07-08T20:03:56+00:00

* configure.in (WARN_CFLAGS): Remove -Wno-deprecated-declarations.
(HAVE_LIBPNG_PNG_H): Don't bother checking for this if we have png.h.
(PNG_DEPRECATED): Define when compiling with older PNG versions.

* configure.in (WARN_CFLAGS): Add -Wno-deprecated-declarations.

Improve static checking when configured --with-ns.

2012-07-07T19:23:41+00:00

See Samuel Bronson's remarks in
.
* configure.in (WARN_CFLAGS): Omit -Wunreachable-code, as it's
a no-op with recent GCC and harmful in earlier ones.
Omit -Wsync-nand, as it's irrelevant to Emacs and provokes a
warning when compiling with ObjC.  Always omit
-Wunsafe-loop-optimizations, as we don't mind when optimization is
being done correctly.

Fix some minor --with-ns problems found by static checking.

Replace some src/s undefs by never even checking on relevant platforms

* configure.in: If --enable-gcc-warnings, disable
-Wunsafe-loop-optimizations for -O1 optimization level.

to avoid compiler warning.  Add eassert.
* src/search.c (simple_search): Initialize match_byte to avoid
compiler warning.  Add eassert.
