Just so you know, yes, we can flatly deny that.  There is *no* contract
between Microsoft and Sage.  Microsoft Research gave us funding
as an unrestricted gift, and mentioned to us that they can't use anything
we give them if it contains GPLv3+ code.  Out of respect we intend
to deliver a version of Sage to them that contains no GPLv3+ code.

I'm very appreciative of Microsoft funding open source mathematical
software development, and I think it is a great step in the right direction.

The *perception* -- wrong or right -- is not that you actually make
much money, but that you try to make money by only allowing
certain code into GMP if you're paid to do so.

OK, that's useful to know.

Why did you reject those files?

Code that goes into MPIR will be refereed in a transparent manner, just
as we do with Sage.
