[PATCH] Fix Wundef warning in glibc in fnmatch.c

[Siddhesh Poyarekar]

Hi,

This patch brings the _LIBC check earlier to avoid checking a possibly
undefined MBSTATE_T, thus fixing a -Wundef warning in glibc.  OK to
commit?

Thanks,
Siddhesh

        fnmatch: Fix -Wundef warnings in glibc.
        * lib/fnmatch.c [defined _LIBC || WIDE_CHAR_SUPPORT]: Check if
        _LIBC is defined before checking MBSTATE_T.
