As Brian said, this was already reported. The ball is now in the CVS
maintainer's court: <http://cygwin.com/ml/cygwin/2006-01/msg01383.html>.

That's exactly right (see line 1002 of server.c).

Yes. Looks like Cygwin is too hasty in assigning the error number: Linux
only returns ENOENT if the directory doesn't already exist, but Cygwin
will always return it for a trailing dot argument. The same with rmdir,
where it would always return EINVAL, even if the directory doesn't exist
(in which case Linux returns ENOENT). FWIW, POSIX only specifies an
action for rmdir() on a trailing dot (EINVAL).
I didn't post earlier because I was trying to test a patch (a variant of
CGF's, though his is cleaner). I'm glad this is fixed.
