I did, i just post it in the message in order to convenience those who are
cut and paste freaks ;)

hmmmm. this is the one i got right off the pgcc web site.. I will look for
the one you mention: 2.95.2 
I am alittle confused: should i look for pgcc or egcs-1.1.x ?
I heard the two were merged, but i am not certain on this..

Yes, i understand this, except I am a speed freak... (and yes i know that
larger size will inversely affect locality and therefore cache performance
in certain situations, but i DID notice speeds ups in my programs due to
faster kernel system call executions (my supposition), and that's why i
wanted to do this..).. Maybe i am mistaken but since I got Celeron CPU's
if i enable the 686 instructions, will pgcc use the MMX and FPU registers
for function calls? (instead of stack)  This should in many cases speed up
things (maybe not that mouch, but by some)..

Thanks for the info
