Sounds good.  There's a bunch of changes I'd like to make including:

- get Float == float, Double == double
- strip out greencard support since the ffi is sufficient
- cleanup internal names used for all the ffi-related primitives
  to match the names used in the ffi spec.
- add a few ffi-mandated C functions that Sven(?) pointed out 
  (hs_free_funptr I think - maybe one or two others)

Mind you, the next 2 months see me moving home, getting married and
drumming up more consulting work so I may not get round to it right
away...
