If the struct is passed by reference of course then you're fine, but if
it's by value then you need a C wrapper. The reason is because it's
beyond the scope of the FFI to know the structure layout and how to map
that to haskell types. That's the domain of FFI pre-processors. However
I don't know

Yes, but programmer *knows* the structure layout, so she usually can emulate
it with a sequence of primary ffi type arguments. It's pretty trivial for
the original example (see my previous post on this subj) and can be extended
