...but a look into the sources did. If you call `id' w/o a
name, id calls getgroups() which in Cygwin returns the group
list from the process token. If you call `id' with a name,
id assumes that you are not the sme person as the one you're
asking for information about. In that case it can't call
getgroups() but searches /etc/passwd and /etc/group by itself.
And /etc/group doesn't contain any supplementary groups in
your case.
