Sorry, it is here now.

--- Clip ----

The patch Kevin provided still does not work on 3.1.  I had already tried
something similar (with the same results) prior to simply hard coding
gmp_cv_gcc_march_pentiumpro=true.   Now I have a patch below which will
work correctly.

Here is the full patch, I hope that Notes does not trash it.  I have tested
it on gcc 3.1 and gcc 2.95.3-6  (both mingw ports), and it works fine.
What I have done is simply used awk to trim just the first line (since the
3.1 gcc --version is multi line).  The sed was nabbing the 2002 from the
date (or nothing), and the unrecognised compiler version message was shown.
This patch fixes that behavior, while still compatible with the 2.xx.xx
--version format:
