GCC again

Now that the new Intel Mac mini is out, it would be nice to upgrade to it at some point, but the question of the old Newton development tools comes up again… I guess there is really no way around replacing the tools with GCC and NEWT/0. For GCC, the problem is that a new backend is needed to take care of the proper creation of the vtables, and last time I looked, NEWT/0 does not create NSOF output, but rather NewtonScript bytecode for functions. Well, I guess neither problem requires rocket science to be solved, just some work :)
