No, I'm not suggesting that. You didn't mention any pentiums, and I
assumed you would be running the code on the 486. If you distribute the
compiled code, make sure pgcc hasn't used any non-i386 instr. (so it will
run on all machines, but run fastest on pentiums.) Obviously, the 486 is
the machine to use for that.
Give the occasional miscompilation of certain code by pgcc, you should be
careful about distributing binaries compiled with it. Normal gcc with
-mpentium might be good enough for you code. Maybe if you ran a benchmark
and found that pgcc was a significant improvement (5 or 10% or more), then
distributing pgcc compiled code would make sense.
