gmp 4.3.2 on Solaris 8, gcc 3.2.2 (old server)

I've been playing with this some more by following a thread on a MySQL
bug report which can be viewed here:

It suggests that it actually takes three fixes to make this work.  There

  o Give "--build=x86_64-pc-solaris2.10" as a configure argument

  o Give "-m64" part of CFLAGS, CXXFLAGS and LDFLAGS

  o Configure and run make like

    % LIBRARY_PATH=/usr/local/lib/amd64 ./configure .....
    % LIBRARY_PATH=/usr/local/lib/amd64 gmake

In order.  I've tried setting that to no avail.  I'm using the stock gcc
on OpenSolaris which is still GCC 3.4.3.  My build= defaults to
core2-pc-solaris2.11 which means dual core Intel with 64 bit extensions
according to the gcc manual and setting build = to x86_64-pc-solaris2.11
results in the same.  I think it's a case of the version of gcc being to
old to even know that those are but I could be wrong.  In any case, it
doesn't seem to help.

gcc has no problems with adding -m64 to the various flags.  I've set
mine to:

CC="gcc -m64"
CXX="g++ -m64"
CFLAGS="-m64 -I/opt/gcc/include -O3"
CPPFLAGS="-m64 -I/opt/gcc/include -I/usr/include/gmp -O3"
CXXFLAGS="-m64 -I/opt/gcc/include -I/usr/include/gmp -O3"

and lastly is the LIBRARY_PATH which I set in LDFLAGS instead.

LDFLAGS="-L/usr/sfw/lib/amd64 -L/usr/sfw/lib -R/opt/gcc/lib"

So between the CC, CXX, CFLAGS, CPPFLAGS, CXXFLAGS and LDFLAGS compiling
gmp, mpfr, mpc went off without a hitch and I've gotten further with gcc
then I have been able to before.  It's still running in the background
as I'm typing this.
