Generating Function Prototypes

[Ashley Yakeley]

I've been having trouble with an imported function that returns 
Int64/"long long". Haskell doesn't generate a prototype, so regular 'int' 
type is assumed.

Why doesn't Haskell generate a prototype from the 'foreign import' 
declaration, as part of the -fvia-C compilation? When the prototype is 
omitted, a default one is assumed. Surely FFI can improve on the default 
with the information given by the 'foreign import' declaration?

In the mean time, how do I work around the problem and provide a 
prototype myself?
