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.
