AFAIK, Cygwin doesn't currently support UIDs of more than 16-bit.  Edit
/etc/passwd and change your user id (third ":"-separated field) to
something less than 65535.  Make sure you don't touch any other part of
the entry.

Also, you will not be able to use "login" to switch user context.  See
<http://cygwin.com/cygwin-ug-net/ntsec.html#NTSEC-SETUID>.
