I'm no compiler expert, but prescott and nocona are Net-Burst architectures.
Core(2) is a pentium-m successor, which was a completely different (x86)
architecture, so optimizations for netburst won't have a positive effect, if
they work at all.
I use CPUTYPE?=pentium-m, but I've never done any comparisions to binaries
compiled without CPUTYPE. After several years observation with CPUTYPE I
guess the improovement ist smaller than ever these days, and until now it was
