There are no alternatives for gcc (cc is different). This is a
deliberate maintenance choice. Forget about using alternatives for this.

CC=gcc-3.2 in the environment, or upgrade the gcc, g++, etc. packages to
ones where the gcc symlink points to gcc-3.2. (You could also
dpkg-divert /usr/bin/gcc, /usr/bin/g++, etc. and put a different symlink
there instead. Just remember that you've done so if you take that
approach.)
