Of the results posted above, the only interesting one that is still slower 
than gcc-2.95 is a pentium 3 with -fPIC.
(Happily, gcc-4.3 is an improvement there, but it's still worse than 2.95.)
Oddly, this one does better with athlon-xp tuning.

/proc/cpuinfo info                                       pic?   tune           
[t_34/t_295, t_401/t_295, t_43/t_295]
cpu family 6,model 11, Intel(R) Pentium(R) III CPU - S 1266MHz, -fPIC
tune=pentium3   [1.37, 1.72, 1.20]

cpu family 6,model 11, Intel(R) Pentium(R) III CPU - S 1266MHz, -fPIC
tune=athlon-xp [2.16, 2.49, 1.10]

I'm not sure how important Pentium III performance is anymore.
