Thanks.  The strace doesn't help, though.  The rmdir of foo works
without any problem, so not even a single debug output is generated.

I have an idea or two what could be the problem of the netapp drive,
but that requires testing with a Cygwin DLL with enhanced debug output
in the unlink/rmdir functionality.

Would you mind to play guinea pig if I send you the link to such a
DLL via PM?


Thanks,
Corinna
