Weird things happen when a friend operator= function is declared within a
class.  See code comments below....

// The first declaration of a friend operator= function is used as the
// default operator= declaration in any class that doesnt define its
// own.

class FooA
{
    friend FooA& operator=(FooA&,FooA&);
};

class FooB
{
    friend FooB& operator=(FooB&, FooB&);
};

class Foo
{
  public:
    // Declaring is enough to prevent the bug but it needs to be
    // implemented for ld (of course)
//    Foo& operator=(Foo&);
};

main ()
{
    Foo f1,f2;
    f1 = f2;
}
