Xcode 3.1.x has definitely both. Unless they messed around with the installation, g++-4.2 will always call gcc 4.2 and g++-4.0 will call gcc 4.0. The only question is which is default and you can change the default (e.g. via gcc_select or directly with the symlinks). What I don't remember is what is the default in which version - and I think it may also depend on whether you upgraded or not - but I just don't remember it's been too long ;).
