According to Matthieu CASTET on 3/4/2008 6:28 AM:
| Also according to my posix reading [1], chown should be able to change
perm to

You read wrong.  POSIX also allows chown implementations to impose
additional restrictions.  And on cygwin, we impose the additional
restriction that you can't change to a uid/gid that isn't recognized by
Windows.

Yes, and cygwin's behavior in this case is still POSIX compliant.
