apt-get install g++-3.4.1 (This pulled down gcc-3.4.1 and the other
3.4.1 tools below, and an updated libgcc, and one other package that I
don't recall what though)

cd /usr/bin
rm g++ gcc gconv gccbug cpp
ln -s g++-3.4 g++
ln -s gcc-3.4 gcc
ln -s gonv-3.4 gconv
ln -s gccbug-3.4 gccbug
ln -s cpp-3.4 cpp

That's it.
