    PyDescr_NewWrapper(PyTypeObject* cls, wrapperbase* wrapper, void* wrapped)

appears to be a function binding, but there is no specified return type. I don't know if this is an error or not but it is unusual, and is breaking my translator script which expects functions to have a particular lexical structure, including a specified return type. What's the correct return type?
