  Yes, that's basically it (or equivalent in a .directve section), but,
indeed, as you point out:

  Nah, it's only libtool and autoconf, nothing to be scared of!

  Yes, that's what we'd want to happen isn't it?  The import stub imports the
symbol from libgfortran, the runtime loader finds it in libgfortran and
performs the forwarding, everything Just Works.  No?

  Urgh.  Don't want to diverge our DLL numbers from upstream if at all possible.

    cheers,
