I'm not sure I follow this - if I do
foreign import ccall "static foo.h foo" foo :: Integer -> Integer
then GHC tells me
Unacceptable argument type in foreign declaration: Integer
Unacceptable result type in foreign declaration: Integer
Can you explain what you are doing that makes Integer get flattened,
please?

Another bug, thanks!
Again, this isn't something we claim should work, but it should
definitely either work or give a nice error message.
I've filed it in trac: #1037.
Thanks
Ian
