It recommends '-march=pentium3' on a NetBSD/amd64 5.99.01 box (GCC
4.1.3), with an Intel Core 2 Quad CPU at 3GHz (Kentsfield core). The
best fit for GCC 4.1.3 would be '-march=nocona', and less so
'-march=pentium-m'. Newer GCC versions support keywords for the Core 2,
but I haven't checked whether your script checks the GCC version and
keeps a list of supported options.
