AFAIK, Windows groups are actually compound users.  As long as the SID you
use in both /etc/passwd and /etc/group belongs to a Windows group, you
should be ok.  I don't know what will happen with a user's SID (this
actually is a question to Corinna, since ACL and group ownership mapping
happens within Cygwin).
