1) Can a template be a friend ? I always thought that only concrete
instantiations
of template can be declared as friend.
2) By the way, "friend" in c++.
I think (I currently have no access to compiler), that in gcc-4.0.2 :
class B{};
class A{
typedef B BB;
friend BB;
};
won't be accepted, although gcc-3.36 did accept this.
If true, why ?
Thank you.
