Nothing, I think. Setup is a non-Cygwin tool so it has nothing
to do with ntsec. Since the ACL of /bin doesn't inherit it's
permissions, newly created files get a default DACL which is
identical to what you see above if your account has admin privs.

This reminds me that setting the default DACL could be a useful
extension to the create_token() code...
