Engage Applink in mingw. Note that application-side module is not

compiled into *our* aplpications. That's because mingw is always
consistent with itself. Having library-side code linked into .dll
makes it possible to deploy the .dll with user-code compiled with
another compiler [which is pretty much the whole point behind Applink].
