I still think we're better off removing header files completely and having the Haskell type completely determine the calling convention employed.

I agree. The Haskell compiler doesn't necessarily need to spit out its own prototypes for the benefit of the C code, but it should be able to compile Haskell without needing the header files. In particular, if I specify this: foreign import ccall "swapHalves" swapHalves :: Int64 -> IO Int64; ...the Haskell compiler ought to call the function as if it returns a "long long" (or other 64-bit signed integer type). -- Ashley Yakeley, Seattle WA
