P.S. "-march=pentium4" is wrong for a Core 2 Duo anyway. It is not a
Netburst CPU and therefore much more simular to a Pentium III

I do not think GCC does some pentium4 optimisations, which are not
in Core 2 Duo.
I don't think so either. But the behaviour (e.g. pipe line handling)
two CPUs is quite different. That's why I would expect that code
with "-march=pentium3" works faster on a Core 2 Duo.
