I did that -- in either case I'm pretty sure that "make install" completes
(7+ hours) with the default 2.96.81 compilers and aborts (1.75 hours) with the
pre-release GCC. That is, the only change is the compilers. I'll be running this
again when I get home tonight. The *compiles* appear to have been successful
but there appear to have been numerical errors at run time. I'll post the
details tonight.

Should I be doing this with a more recent developer snapshot of Atlas? I'm
using the 3.2.1 tarball at the moment. I'll probably download gcc 20010521 as
soon as it's available (in theory, that's yesterday :-). I'm in no particular
hurry to get this system stable -- I have another system (Windows 2000 400 MHz
Celeron) that is plenty fast to do what I need to do musically in the near term,
so it's no big deal to wipe the hard drive and start something over. I
volunteered to test GCC 3.0 on the stuff that I'm using (Athlon, Atlas, FFTW,
sfront, octave and R).

I don't remember -- I'll look through the log files when I get home.
