Ok.  I was able to duplicate this behavior with the Cygwin CD DLL.  It
is apparently a long standing bug which Corinna fixed just a couple of
days after the CD was pressed.

I have also changed the error returned from "EISDIR" to "EPERM" as was
suggested by another post.  I was confused by the behavior of 'rm' which
must be doing its own checking.  A simple program that performs an
unlink() returns EPERM on every UNIX system that I tested it on.
