Oh, I was looking at 3.1.1 from the Debian packages. It looks like
they patched config.{sub,guess} and replaced them with newer versions.
That would explain it.

BTW, preliminary analysis suggests that using gcc 3.0.2-pre makes the
library much slower than with gcc 2.95.4-pre. I'll see if I can get
more conclusive results. My tested consisted of running 'primes', and
it took a lot more CPU time when gmp was compiled with gcc 3.x.

However, I may have messed up some of the CFLAGS inadvertently, so I
will try to verify these results and present benchmarks.
