Argh. And 6.6 was working before, wasn't it, with LANGUAGE CPP #-} in
that file? What the heck, 6.6. You used to be cool, man.
Well, we could either revert my patch, or we could remove the CPP
pragma. All GHCs should work without the CPP pragma because of -cpp,
and if the issue with 6.6 is that it can't handle multiple LANGUAGE
pragmas, then removing CPP (to leave just the one GADTs pragma) will
fix it.
However, maybe the problem is that GHC simply can't handle the GADTs
pragma in any way shape or form? In which case unpulling the patch is
the only approach. 6.6 users?
