    I just installed MS VC++ 4.1.  The following code (strained 
from my larger code) now fails to compile:

    class A { virtual ~A() };
    class B : public A {};

    void test( const A&  a )
      {
        const B& b = dynamic_cast<const B&>( a );
          // gives "... error ... cannot use dynamic_cast to 
          // convert from 'const A &' to 'const B &' "
      }

    Did Microsoft goof or did I?  The draft standard (Sect. 5.2.6) 
seems to equate a reference to an lvalue for dynamic_cast, but 
gives no clear wording for this case.  The same problem happens 
for const A* to const B*.
    If the new MSVC++ behavior is correct, why?
(Eagerly awaiting BC++ 5.0, hope it really works with MFC)
