* posix/fnmatch.c (STRUCT): Define.

	(fnmatch): Pass NULL as last argument to internal_fn{,w}match.
	* posix/fnmatch_loop.c (struct STRUCT): New type.
	(FCT): Add ends argument.  If ends != NULL and normal * is
	seen in the pattern, store current pattern and string pointers
	and return.  Adjust recursive calls.
	(EXT): Adjust FCT callers.
	(STRUCT): Undef at the end of the file.
	* posix/Makefile (tests): Add tst-fnmatch2.
	* posix/tst-fnmatch2.c: New test.
