Thanks for the responses.  I did find after posting my question that I
was using the wrong linker, switching to g++ helped.  But I did have
to move some files from /usr/lib64/gcc/x86_64-suse-linux/4.0.2/32 one
level up.  And also copy crt?.o from /usr/lib to /usr/lib64 to get my
file to link correctly.  Even with the "-m32" flag, the system kept
looking in the "64" directories for libraries and the "crt?.o" files.
The better thing to do seems to be to set up different boot
