Subject: (UTILS_FUNC_DIRFD): Test the cache variable, not one that is
 guaranteed to be `no'.  Use `no_such_member' to indicate that condition,
 rather than `-1' which is slightly misleading. Change the name of the cache
 variable to have the gl_ prefix. Prompted by a patch from Richard Dawe for
 DJGPP.
