I could add that my athlon 1.2 GHz results I posted earlier were about the same. Results from P3 and P4 computers would be very interesting - especially P4.

Nice results for intels compiler. How machine dependent is this result?
This was on my Athlon XP 1900+ (1G6Hz), so it seems that at least Athlon XP benefits.
This is the compilation flags used:
icc: -Ob2 -ipo -ipo_obj -axKW -O2 -g gcc: -O3 -pipe -fomit-frame-pointer -march=athlon-xp -mcpu=athlon-xp -g
"-ax<codes> Generate code specialized for processor extensions spec- ified by <codes> while also generating generic IA-32 code. <codes> includes one or more of the following characters:
i -- Pentium Pro and Pentium II processor instructions M -- MMX(TM) instructions K -- Streaming SIMD Extensions W -- Pentium(R) 4 New Instructions"
I tried to get it to run machine code, but I got obscure linking errors (compilation went fine). It seems that some objects missed eval_instruction().
