+ 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.
+
Merge from gnulib, incorporating:
