pcc also generates fast code. faster than gcc on vax at any rate.. i 
should do a more involved comparison than the little shootout between gcc 
and pcc and ultrix/vax cc that ragge and i did.. though we had machines 
of somewhat different characteristics, but pcc2's code was at least as 
fast as gcc's best optimization.

 pcc was in net2 though, wasnt it? it's not encumbered code.
