Update.

	* posix/fnmatch.c: Put internal_fnmatch in separate file.  Include
	twice, to define singlebyte and multibyte version.
	(fnmatch): Differentiate between singlebyte and multibyte locale and
	call appropriate internal function.
	* posix/fnmatch_loop.c: New file.
	* posix/Makefile (distribute): Add fnmatch_loop.c.
