I was looking at the x86-64 specfile and was surprised to see that it wasn't
x86-64 the -march flag was set to k8 for gcc 3.4, when it should be x86-64.

I understand that there's some people in sourcemage who have amd64 processors
however, I don't, I have the intel version that uses the x86-64 specifications
(called extended memory 64 technology)

gcc doesn't have em64t as a valid arch spec (not even in v4.1) the closest
thing I
can pass to gcc is x86-64

I would propose a change to the specfiles and move the current x86-64 and
x86-32
to k8-64 and k8-32, and change the x86-64 and x86-32 to the more generic
-march=x86-64, also I would change the x86-[64,32] gcc 3.3 to -march=pentium4

This way would provide arch specs for both amd and intel implementations of
the
arch specification x86-64.
