Of course, the kernel does compile fine with gcc3.2, as do all the extra
modules I've encountered. So unless you actually have to deal with
something that won't (and nVidia drivers work fine for me), you may find
it simpler to do as I do and not bother with gcc2.95.3 at all... More
work if you later find you *do* need to use 2.95.3 for something, but
less if you don't.
