problems building gcc 4.0.1 on Solaris 9

[Richard Gillman <R dot Gillman at nerc dot ac dot uk>]

When building gcc 4.0.1 on Solaris 9, I get

ld: warning: file 
../build-sparc-sun-solaris2.9/libiberty/libiberty.a(hashtab.o): wrong 
ELF class: ELFCLASS64

xstrdup                             build/genmodes.o
ld: fatal: Symbol referencing errors. No output written to build/genmodes

This is my script for running configure:

#!/usr/bin/sh
umask 022
cd /local1/dick1/dick1/gcc
# /usr/sfw/bin/gtar xvfp gcc-4.0.1.tar # tarball doesn't like Sun tar
#
# start from a clean sheet
rm -rf gcc-d/*
#mkdir -m 755 gcc-d
cd gcc-d

So, I am specifying CFLAGS -m64, but it looks like CFLAGS isn't being 
carried through to the build of these components.

If I now add change the CC definition to
CC="/nerc/packages/gcc/3.4.2/bin/gcc -m64"

I get a lot further, as far as

stage1/xgcc -Bstage1/

Is this a bug with a solution?

Any suggestions as to what I do next?

tia, Dick
