Yes, but it was not possible for the 'glob' module to specify one or the
other, because if the user wanted the other fnmatch module, it would collide.
This is now fixed.

The only GNU extension from fnmatch that glob uses is FNM_CASEFOLD, and only
for Amiga and VMS platforms. Porting efforts to these platforms are long
dead. I would suggest to remove this use of FNM_CASEFOLD, and let 'glob'
depend on 'fnmatch-posix' instead.

We use that naming pattern only when there is more than one module.
If we were to introduce a second 'glob' module that supports only POSIX [1],
then I would agree to rename the existing module. But if there's only
one choice, the renaming is gratuitous trouble for the gnulib users.
