Probably not. I assume the job of getgroups() is much easier on Linux.
It just has to list the gids in the group list. Cygwin fetches the
/etc/group file and verifies for each entry if its SID is in the process
token. Avoiding dups requires YA loop in the loop, I don't think it's
actually worth the effort.
