In Microsoft mode, within class scope, if a CXXScopeSpec's type is equal to the type of one of the base classes then downgrade the missing typename error to a warning. Up to now this is the only case I found where MSVC doesn't require "typename" at class scope. Really strange!

Example:
template<class T> class A {
public:
typedef int TYPE;
};
template<class T> class B : public A<T> {
public:
A<T>::TYPE a; // no typename required because A<T> is a base class.
