I am easily confused. It certainly makes more sense fir ia64 to be
Intel, not AMD. :-)

I have applied the following patch to document the cpus supported by
each define.
Martin mentioned that he has applied a special 64-bit kit to do the
compile, so perhaps he needs it, but most will not. I will keep the
patch around and see if others need it during beta.
