Is there any hope of this working one day?  What would it take?  I suppose
this is an autoconf issue, not a libtool one but am I wrong in thinking that
in some more complete sense of msvc support that it should work?

I blew away all the stuff related to autoreconf and re-ran it and now it
works.  If someone is interested in figuring out more about what's going on
here, let me know and I'll revert the patches and re-test, etc.

This works.

So does this.

Thanks for your help.
