Error: "cannot use values types here"

I'm working on bringing Claw-Torch up to date. The first problem I ran into when trying to compile the generated bindings file was an error cannot use values types here. The fix is one word:

Translating function pointers as :void caused the error when a parameter was of function-pointer type; a parameter can't be void. I poked around CFFI a little and saw evidence that it also translates function pointers as :pointer (though arguably, there should be a distinct type :function-pointer, as C++ does not require them to be the same size as ordinary pointers).

I just looked at PR #16; it's the same issue, with almost the same fix suggested.
