    I don't know the state of this problem, but I do know that Alex Oliva
    has a patch which auto-detects cases when we need to use long long for
    HOST_WIDE_INT.  That's probably a cleaner solution than hacking up the
    xm files to do this.

I don't like that patch either, for essentially the same reason as you, but
also because using long long for HOST_WIDE_INT is sometimes problematical
and I'm leery about it happening as automatic as the above way. If we
auto-detect we can, theoretically at least, do enough testing to verify
that it actually works.
