+is not possible to declare an Objective-C class from plain old C or C++
+code.  Furthermore, because of C++ name mangling, the type name must
+be the same for both C++ and Objective-C++ code.  Therefore, we define
+what should be a pointer to an Objective-C class as a pointer to a plain
+old C struct with the same name.  Unfortunately, because the compiler
+does not see a struct as an Objective-C class we cannot declare it
+as a struct in Objective-C(++) mode.
