imported return type not masked

This might be difficult to reproduce. Try this:

Haskell looks like this:

foreign import foo :: IO Word8

do {
 f <- foo;
 putStrLn (show f);
}

C looks like this:

HsWord8 foo ()
  {
  HsWord8 f;
  ... f should be zero
  return f;
  }

On running, I might get something like this:
1074803456

...which is clearly not a Word8, although the low byte is zero.
