> The constructor for `CInt` is not hidden, just import `CInt(..)`.
I looks like CInt constructor is imported since GHC-7.4 but was hidden
until GHC-7.2. Importing CInt(..) gives a warning on GHC-7.2 whereas
importing CInt gives a warning on GHC-7.4. Hm. Maybe I should import the
types with qualification.
Btw. if the type would be named Int in the module Foreign.C.Types I would
already use qualification and write C.Int.
