<pre>7.3.1.2/3:
"If the name in a friend declaration is neither qualified nor a template-id and
the declaration is a function or an elaborated-type-specifier, the lookup to
determine whether the entity has been previously declared shall not consider
any scopes outside the innermost enclosing namespace."
Therefore a (not-yet-declared) 'template<typename V> class B::Class1;' is
befriended, not the global Class1.
=> This is a GCC bug, not a Clang bug.</pre>
