[ long story deleted... thanks Marcin. ]

To summarise GHC's FFI support:  in the upcoming GHC 5.00 (not long
now!) we have the latest FFI libraries, and we've bundled Marcin's
hsc2hs tool.  This means writing bindings to C libraries is fairly well
supported out of the box; if you want something more sophisticated then
the other tools mentioned in this thread are available.

Cheers,
