Ok, what has changed from your previous version that I rejected that is
going to actually allow this to build?

Hint, you gotta tell me what version of the patch this is, and what
changed, otherwise I'll just assume this is a resend of the previous
patch and go ahead and delete it from my queue.

In fact, I might as well do that, now deleted :)
