Bruce,

I didn't change the source tree at all.  I used:

env CFLAGS='-O3 -m64' LD='/usr/bin/ld -melf_x86_64' ./configure --with-CXX --without-zlib

with the experimental gcc and bintils from www.x86-64.org.  I needed
--without-zlib because I don't have a 64 bit compile yet for zlib.

make
make install-all-headers
make check CC='gcc -m64'

The last one is needed to make sure that the shared library gets made
in the amd64 architecture.

That's it!
