I'd recommend selecting the 'Exp' button actually. That ensures that
all dependencies of gcc, e.g. libgcc and libffi, are upgraded to 4.5
too. (It's yet another flaw of setup.exe that it doesn't automatically
upgrade dependencies of experimental versions accordingly.)

Of course this also selects experimental versions of a few other
packages, e.g. emacs, but if you don't want to help testing those, you
can downgrade them on the Pending page.
