Seems from the date of this "sgicc" that they killed the Pro64 project
just when they got started on the C/C++ front ends.  It looks like the
infrastructure for OpenMP in WHIRL and their F90 compiler uses it but
they never got around to implementing it in the C/C++ front ends.  What
a shame  :-/

P.S. Iis "2.96 20000530 (experimental)" the same version of "GCC" that
used to ship with Redhat?
