Switching to V3

[Mark Mitchell]

I'm running a V3/IRIX bootstrap right now.  If I see the same problem,
I'll fix it.  Otherwise, we'll have to see what's different about your
IRIX box from the one I'm using.  (It's possible there are real
differences; "my" IRIX box is a 4000-node supercomputer with funky
hardware; it may well have slightly different headers or something.)

I also don't do --enable-pthreads; one step at a time.
