Of importance is the group id 544, which is, according to the Cygwin docs:

administrators                  S-1-5-32-544

See: http://www.cygwin.com/cygwin-ug-net/ntsec.html

As such it would be nice if you could add a test that checks for
administrator group membership on cygwin only, using the GID value.
