Implement the CTYPE pragma; part of the CApiFFI extension
For now, the syntax is
type {-# CTYPE "some C type" #-} Foo = ...
newtype {-# CTYPE "some C type" #-} Foo = ...
data {-# CTYPE "some C type" #-} Foo = ...
Don't we now have a problem with needing header files to define these
types? What if a module in another package uses one of these types in a
foreign import capi?
Also, attaching C types to type synonyms seems a bit fragile - type
synonyms are ephemeral things, and I'm worried the type annotation could
easily get lost.
Cheers,
Simon
