Hi,

I've been merging my recent additions to the release branch and came 
across the BOOST_NO_NESTED_FRIENDSHIP macro, which hasn't been merged. 
Looking at its description and test, I'm not certain whether this macro 
actually flags a compiler deficiency, rather than valid behavior. Here's 
the description:

   If the compiler fails to support access to private members
   from nested classes

And the test:

   class A {
      static int b;
      class B {
         int f() { return b; }
      };
   };

To my understanding, 11.8 says that it shouldn't compile, as B doesn't 
have any privileged access to A::b. Am I missing something?
