Short description: fnmatch() fails with MBCS.
Author(s): Fedora glibc team <glibc@lists.fedoraproject.org>
Origin: PATCH
Bug-RHEL: #819430, #826149, #826151
Bug-Upstream: #14185
Upstream status: not-submitted
fnmatch() fails when '*' wildcard is applied on the file name
containing multi-byte character(s)
This needs to be reviewed thoroughly and go upstream with a
new test case.
