No, but pgcc -O2 should be _very_ close in compile speed to egcs -O2,
likewise -O. Without optimization they both should be equally and very
fast.

Well, most people using pgcc indeed use it to have fast programs. But -O2
will keep being about as fast as gcc -O2 since I do not want to introduce
many differences between gcc -O and pgcc -O2, so I can still reasonably
easy check wether a bug is caused by gcc or by pgcc code.
