Here's my result: PGCC installed fine. Compiling with -O6 -mpentium, my
new binary of my 3d engine was SMALLER than before I got PGCC.. by about
half a K. The FPS count went up from 16 to 18. So I guess it works.

my 3d engine is: http://umn.edu/~jawed/jaw3d/

Is it safe to distrib. this Pentium optimized version? Or should I wait
until it becomes more... stable? debugged?
