Secondly, has Gtk2Hs compatibility been tested with GHC 6.10? In the past there have sometimes been problems with new GHC releases and Gtk2Hs. These have always been addressed, but it usually took a few months..

I just built Gtk2Hs with the 6.10-rc on Windows, and it seems to work. The release version, 0.9.13, is a no-go though: I needed a patch (related to an "instance Binary Integer") before I got it to compile. And a lot of other messing about as well, but I've got used to that on Windows.
