strncasecmp: Work around Solaris, Cygwin bug. * lib/strings.in.h (strncasecmp): Consider REPLACE_STRNCASECMP. Use the usual idioms. * m4/strings_h.m4 (gl_STRINGS_H_DEFAULTS): Initialize HAVE_STRNCASECMP, REPLACE_STRNCASECMP. * m4/strncasecmp.m4 (gl_FUNC_STRNCASECMP): Invoke gl_STRNCASECMP_WORKS. Set REPLACE_STRNCASECMP. Assume that HAVE_STRNCASECMP is initialized. * modules/strncasecmp (Files): Add m4/strcasecmp.m4. (configure.ac): Consider REPLACE_STRNCASECMP. * modules/strings-h (Makefile.am): Substitute HAVE_STRNCASECMP, REPLACE_STRNCASECMP. * doc/posix-functions/strncasecmp.texi: Mention the Solaris, Cygwin bug.
