 State-Changed-Why:
     Not a bug.  The 's' inside 'C<T>' is hidden since the base
     class 'C<T>' depends on the template parameter 'T'.  Only
     the 's' in 'B' is visible.  Here is the relevant part of 
     the C++ standard that describe the behavior:
     
     14.6.2 Dependent names, para 3:
      In the definition of a class template or in the definition
      of a member of such a template that appears outside of the
      template definition, if a base class of this template depends
      on a template-parameter, the base class scope is not examined
      during name lookup until the class template is instantiated.
      [Example:
       typedef double A;
       template<class T> B {
         typedef int A;
       };
       template<class T> struct X : B<T> {
         A a;  // a has type double
       };
      The type name A in the definition of X<T> binds to the 
      typedef name defined in the global namespace scope, not
      to the typedef name defined in the base class B<T>. ]
