Ah, right!

I was intending to support C++ classes via the same API, so users only needed one code path to build C++ and ObjC class hierarchies (the same cursor will never be both a valid C++ and ObjC class, so the hierarchies will be distinct).

With C++, we have the CXCursor_CXXBaseSpecifier cursor.  It encapsulates both the reference to the super class as well as the access control and kind of inheritance.

We should probably not to overly collapse APIs for querying the two object type systems from Objective-C and C++.  While they both have the notions of superclasses, they semantically are very different.
