The point I was making before, is that CPUTYPE isn't just passed
transparently to gcc, it's used for setting other varia

If you set CPUTYPE, -march is set to match, so setting -march=native

Yes, if you are using i386.
Most CPUs have the same default CFLAGS, it's the value of CPUTYPE
that's passed to the compiler that determines processor optimizations.

It depends on what you'

/etc/make.conf ?
As an example, let us consider a FreeBSD 7.1 system running on a
