  I am afraid you need to do a full port, because AIX has quite peculiar
ideas about file access rights vs. uids/gids of programs.  Those relate
to the overall porting problems that people experience.
(Doing setreuid() doesn't necessarily affect file access rights...)

There is (at least was two-three years ago) a FAQ on porting BSD programs
on AIX.   It IS possible, although sometimes somewhat painfull...
I seem to recall also some AIX manual about this particular subject,
but what it was I don't remember.

Picking proper values for hostenv isn't the problem, picking proper
methodology on  setreuid() et.al. is, and I can't do it blind-folded
(without AIX 3.2 machine, and documentation), but perhaps I can arrange
somebody to try their hand on it.
