  gmp 4.1 + all patches
  ./config.guess is athlon-pc-linux-gnu
  
  ./configure --enable-mpfr --disable-shared --build=athlon-pc-linux-gnu 
  --host=athlon-pc-linux-gnu CC=gcc-3.2.1 CFLAGS="-O2 -fomit-frame-pointer 
  -march=athlon " --exec-prefix=/usr/local/athlon
  
  make
  
  compile gmperr.c with
  
  gcc-3.2.1 gmperr.c -o gmperr /usr/local/athlon/lib/libgmp.a
  
This might be hard for somebody else to reproduce, since the
environment requires lots of work to set up.  I think we
need your help.

I tried GMP 4.1.1 (which is ready and waiting to be uploaded
to ftp.gnu.org) on an athlon-pc-freebsd system using gcc
2.95.  It does not fail.

This might be a bug in GMP, perhaps then a fioed bug.  Or it
might be a bug in gcc 3.2.1.

The first thing to try is to try a different compiler, or
use gcc 3.2.1 but disable optimization.  Could you please
try that?
