EDG and Solaris CC also accept it, clang doesn't
The code looks similar to this example from [class.protected] in the standard:
class B {
protected:
int i;
static int j;
};
class D1 : public B {
};
class D2 : public B {
friend void fr(B*,D1*,D2*);
};
void fr(B* pb, D1* p1, D2* p2) {
// ...
p2->i = 3; // OK (access through a D2)
p2->B::i = 4; // OK (access through a D2, even though
// naming class is B)
// ...
B::j = 5; // OK (because refers to static member)
D2::j = 6; // OK (because refers to static member)
}
Note that the friend of D2 can access non-static members of B through D2* and
can access static members of B directly.
