Yes. So there are a couple of things here. First, the dll has
SO_MAJORVERSION in the name. And second it stops building any static
libraries and instead builds windows import libraries with names like
lippq.a.

I've tested this on both HEAD and REL9_3_STABLE and it works fine.

I think we should apply this to HEAD. If it's not too late it would
probably be a good thing for release 11 - would need a release note.
