[Bug c++/13935] [3.4/3.5 Regression] Template friend lookup bug

Well, when I say:

friend class B;

I'm saying that ::B is a friend of MainClass<> (and ::B is thus predeclared). 
Then, I'm defining MainClass<>::B<>, which is a totally unrelated type. I don't 
see how this could be illegal.

I think the crucial point is about this:
template < class TP2 > friend class B;

Does this refer to ::B or to MainClass<>::B<>? How is the lookup performed, 
exactly? There are a couple of DR in TC1 about name lookup issues of friend 
templates, I'll give them a deeper look.
