--- Comment #1 from Richard Smith <richard-llvm at metafoo.co.uk> ---

"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.
