Oh -- not one version of Int for 32-bit execution and another version for 64-bit execution? Seen on #haskell today:

Yeah, that is actually a difference between jhc and ghc, jhc always uses a 32 bit type for 'Int', while with ghc it follows the machines pointer size. But they do both implement it as a standard haskell data type with a single unboxed component. I used the jhc definition in my message as I couldn't remember the exact way ghc defined it off the top of my head. Although, I don't think any such user visible representation of Int or other basic types should be mandated by the standard, I think it can be useful as a way to express a portable denotational model for understanding what operations on these types mean.
