Under mingw or cygwin, possibly. Natively, not.

Possibly you just need to move the coercions to a single more manageable
location. e.g. you could rename the FFI calls, then wrap them with a
simple coercion function, and call it by the original name.
inject :: CInt -> Int
eject :: Int -> CInt
foreign import ccall "blah" prim_blah :: CInt -> CInt
blah x = inject (prim_blah (eject x))
By the way, there are tools for generating FFI bindings that can create
code like this (e.g. GreenCard).
