I think my answer was on the money, actually.

If it isn't clear by now that we accept contributions and that we don't

Or, maybe that's another FAQ entry

I have some changes that I've made to the Cygwin DLL.  Will they be accepted?

Yes.  Patches are gratefully accepted.  However, to minimize email churning,
please check out the Contributing link at .
