optimaly ( ;-> ) one would simply use --target <arch> . or better yet -
put in a macro to autodetect the optimal architecture (shouldn't be hard).

I would put in pentium4, if not for my unsuccessful attempt at getting
more juice from a recompilation. PPC and IA-64 if we have a cross
compiler (and then more architectures). x86-64 when it will be available.

I assume, of course, you mean PIII :-) AFAIK all three are not that different from
each other and are all based on the same core (or similar - as there were several
vesions of the last two) with the same instruction set - the main differences between
those processors are about heat disipation, cache sizes and cache frequency.
