gcc v3 issue -- hacky solution

[Christopher Faylor]

If we can generate new operators for all of the builtin types that are
currently being used in setup.exe, then, if we compile everything with
-fno-exceptions (which I've just added to Makefile.in) we won't have to
worry about having a mingw version of libstdc++.a around.

It's a hack, I know, but the alternative of somehow building a mingw
version of the stdc library is not too attractive.

So, if anyone was looking for something, oh I don't know, repetitive to
do, that would be a good project, assuming that Robert agrees.

(Unfortunately, my internal Robert simulator gives this about a 30% chance of an
agreement)
