gcc bails out on the attached code with:

  test.cpp:8: no type named `B' in `class A'

Moving the forward declaration above the friend declaration
solves the problem. As the two don't refer to each other
I don't see why the order should make a difference, though.

//////////////// test.cpp ////////////////

class A
{
    friend void abc();
    class B;
};

class A::B
{
};
>How-To-Repeat:
gcc -c test.cpp
