(not really addressed at me, but what the heck) I once tried getting the
pentium optimised GCC and compiling my chess program. Result: about 2 %
slower than the standard GCC (2.7.something back then) even when running
on a pentium. So then i tried compiling with -m386 and that turned out
to be faster than -m486 on both a 486 and a pentium. (again only a few %
difference).

Now i use the standard gcc compiler with the Linux distribution, with
flags
-O2 -fomit-frame-pointer -m386

I guess i must code in a different style to everyone else. I've also
found that GCC is no worse than Digital Unix C on an Alpha, for my
programs. Gcc was 10% faster on one program, about the same for two
others, including the chess program. Nearly everyone else who has used
it says gcc is hopeless on Alphas.
