No, you really should extend IUnknown, it's going to be massively
confusing otherwise.

Please do proper reference counting, it doesn't cost anything, and
someday we might need it. If you can't use standard ref counting it
probably means you are doing something wrong.

You don't have to include any of the headers, that's the whole point
of interfaces. Just have wined3d export an IWineD3DUser interface and
have both d3d8 and d3d9 implement it. wined3d doesn't have to know
anything about the implementation, just like d3d8 and d3d9 don't have
to know anything about the implementation of IWineD3D.
