This means GetShortPathName fails, and the error code doesn't make any
sense.  Are you sure you stopped _after_ this line:

      DWORD err = GetLastError ();

?

Anyway, if GetShortPathName fails, I will try to come up with a fix
that works at least when path and module are either both short or both
long file names.
