Yes, there is a way. Thanks for the hint, I have patched my patch.

ChangeLog:
==========

Sat Jan 30  1:31:00  Corinna Vinschen  <corinna DOT vinschen AT cityweb DOT de>

        * fhandler.cc (fhandler_disk_file::fstat): Handles directories,
        returns unique i-node number.

        * syscalls.cc (stat_worker): On WinNT, stat_worker calls
        fhandler_disk_file::fstat for directories, too.
