Hi Mike,

Thanks for the information. I checked the gcc manual and there is also
a core2 option:

           nocona
               Improved version of Intel Pentium4 CPU with 64-bit extensions,
               MMX, SSE, SSE2 and SSE3 instruction set support.

           core2
               Intel Core2 CPU with 64-bit extensions, MMX, SSE, SSE2, SSE3
               and SSSE3 instruction set support.

This is gcc version 4.1

Cheers,

Hector
