Shouldn't set[re]gid look at the group list?

I just noticed that setregid() fails for groups which you are a member of,
but which are not the current group. That is, if id(1) reports
uid=202(urlichs) gid=90(one) groups=90(one),5(two)
then setregid(5,5) fails with EPERM.

I wonder if that behavior is mandated by any standards.
Otherwise, IMHO this restriction should be removed.
(Same for setfsgid().)
