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 just reject patches out of hand then I give up. 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.
