No.  This is another weirdness.  This does not happen for me on my
VMware win2k.  What happens for me is this:

  $ ls -la //server/share/non-empty-dir
  total 0
  drwxr-xr-x 1 corinna None 0 Feb 27 15:37 .
  drwxr-xr-x 1 corinna None 0 Feb 27 15:37 ..

But:

  $ ls -l //server/share/non-empty-dir/file
  -rw-r--r-- 1 corinna None 49 Feb 27 15:38 file

When running readdir() it doesn't find any file in the directory.  The
reason is that the first call to NtQueryDirectoryFile in
fhandler_disk_file::readdir() fails with a very strange error I never
saw before and I don't find any useful information about on the net:

  0xC00000C3 STATUS_INVALID_NETWORK_RESPONSE

If I switch the NtQueryDirectoryFile call to retrieve only one entry per
call, it works fine!  But it fails always with the above status code if
I let it retrieve as much entries as fit in the buffer.

I tracked down exactly when I introduced this problem:

  http://cygwin.com/ml/cygwin-cvs/2007-q3/msg00058.html

But I have not the faintest idea what is causing it.  Blaeh :(
Maybe we should drop Win2K support...
