+
+       * configure.in (WARN_CFLAGS): Add -Wno-deprecated-declarations.
+
+2012-07-07  Paul Eggert  <eggert@cs.ucla.edu>
+
+       Improve static checking when configured --with-ns.
+       See Samuel Bronson's remarks in
+       <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00146.html>.
+       * 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.

+
+       * configure.in (BROKEN_SA_RESTART): Doc fix.
+
+       * configure.in: Rather than checking for things then undef'ing
+       them on some platforms, simply don't check for them.
+       (getwd): Don't check for it on unixware.
+       (random, rint): Don't check for these on hpux.
+       (res_init, libresolv): Don't check for these on darwin.

+       * lib/makefile.w32-in (GNULIBOBJS): Add $(BLD)/c-ctype.$(O),
+       $(BLD)/c-strcasecmp.$(O) and $(BLD)/c-strncasecmp.$(O).
+       ($(BLD)/c-ctype.$(O), $(BLD)/c-strcasecmp.$(O))
+       ($(BLD)/c-strncasecmp.$(O)): New dependencies.

+       * configure.in: Document --enable-gcc-warnings better.
+
+       Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
+       This is safer than strcasecmp, which has unspecified behavior
+       outside the POSIX locale and in practice sometimes does not work
+       in multibyte locales.  Similarly for c_strncasecmp and strncasecmp.
+       * configure.in (strcasecmp, strncasecmp): Remove checks.
+
+       * lib/c-ctype.c, lib/c-ctype.h, lib/c-strcase.h, lib/c-strcasecmp.c:
+       * lib/c-strncasecmp.c: New files, taken from gnulib.
+       * lib/gnulib.mk, m4/gnulib-comp.m4: Regenerate.
