Because you're a sadistic bastard :-) :-)

Well, I was hoping to get some data, particularly from a benchmark other
than daxpy that what I was doing isn't absurd :-)  I'm pretty sure the daxpy
loop will improve :-)


How long does it take to build just a stage1/cc1 and stage1/f771 without
debug or optimization?  That's typically what I do to test this kind of little
stuff quickly on my slower machines.
