status of GreenCard support

c2hs seems to be quite stable. It's used in gtk2hs which exists for a
long time now. c2hs is one way only. There is yet another tool: hdirect.
But because its using an extra description language (IDL) it seems to be
not the best choice for this task. It has been developed to interface
with COM on windows. Please correct me if I'm wrong ;-)

When using cabal and GreenCard it might be the case that you have to
tweak setup.hs to add --libdir parameters. Probably it would be better
to update cabal. Maybe I've missed a point to configure it correctly?
If I can save you some minutes by dropping you me quick setup.hs hack
let me know it.
