Your problem here is not GCC but rather is DYNIX's retarded dual universes,
which IMO is just a way of avoiding the task of integrating the two worlds,
like virtually every other Unix vendor has done.  Vendors have been providing
this for many years, so much so that a lot of sources in comp.sources
assume routines from both universes.  These things compile with
no problems, in general, on most systems, but it is a pain on DYNIX.
This has been a pain for us when doing development work for our
distributed programming language, SR, on a Sequent Symmetry running 
DYNIX.
