[PATCH] Fix -Wundef warnings in fnmatch.c

[Siddhesh Poyarekar <siddhesh at redhat dot com>]

Fixes -Wundef warnings for MBSTATE_T and HAVE_STRING_H.  The
HAVE_STRING_H bit is a merge from the gnulib fnmatch.c and the
MBSTATE_T fix has been posted to gnulib for inclusion.

Tested that the code is unchanged on i386.

Siddhesh

	* posix/fnmatch.c: Include string.h unconditionally.
	[defined _LIBC || WIDE_CHAR_SUPPORT]: Check if _LIBC is
	defined before checking MBSTATE_T.
