Tags: patch
Emacs currently use 'strcasecmp' and 'strncasecmp' for
case-insensitive comparison but these have problems in multibyte
locales. In practice Emacs code really just wants a C-locale
version of these functions so I'm planning on installing the
following patch after some more testing. I'm giving some
heads-up as this affects the Microsoft ports.

+ Use c_strcasecmp for portable ASCII case-insensitive comparison.
+ 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.
+
Clean out last vestiges of the old HAVE_CONFIG_H stuff.
* lib/makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.

2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
+ Use c_strcasecmp for portable ASCII case-insensitive comparison.
+ * dispextern.h (xstrcasecmp): Remove decl.
+ * dosfns.c, font.c, fontset.c, ftfont.c, image.c, nsfns.m, nsterm.m:
+ * process.c, w32.h, w32font.c, xfaces.c, xfns.c, xfont.c:
+ Include <c-strcase.h>. Replace all uses of xstrcasecmp with
+ c_strcasecmp.
+ * xfaces.c (xstrcasecmp): Remove.
+ * xfont.c (compare_font_names): Rewrite to avoid casts.
+
Clean out last vestiges of the old HAVE_CONFIG_H stuff.
* Makefile.in (ALL_CFLAGS):
* makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.
