The code compiled fine on the 7447A machine (running gcc 3.4.4 on a linux 2.6.14, libc 2.3.6), but I got compile errors on my 970 (2.6.21, gcc 4.1.2, libc 2.3.6)

This is the sound of me grumbling:  Argh, argh!

Something is going wrong in ./configure, and it's not detecting that
it's supposed to use '-Wa,-mregnames', as well as some other flags.
My guess is that m4/as-host-defines.m4 is not defining HAVE_POWERPC
because the ${host_cpu} is not recognized.

This may not be the only problem, however.
