Windows gtk3-client might be badly broken. I've got a report that one
crosser-based build I made just a couple of days ago doesn't show any
graphics at all. While the sources used in the build are nothing we're
about to release, changes to that tree since previous working build
have been mostly patches that have gone to S2_4 too. I'll test and
debug what I can, but we cannot release anything before we've
confirmed that it works.
