>Description:
If class A defines a couple of overloaded methods (virtual or not), and one inherits this class in another class, let's say B, that redefines one of these methods, the other overloaded methods from A are not accessible anymore without prepending "A::".
>How-To-Repeat:
#include <iostream>

using namespace std;

class A
{
public:
  void f();
  void f(int);
};

void A::f() { cout << "A::f()" << endl; }
void A::f(int) { cout << "A::f(int)" << endl; }

class B : public A
{
public:
  void f(int);
};

void B::f(int) { cout << "B::f(int)" << endl; }

int
main(int argc, const char **argv)
{
  A a;
  B b;

  b.f();  // <-- compilation fails here: no matching function for call to `B::f()
}

State-Changed-Why:
    not a bug. this is the correct behaviour. you need
    a using declaration to do what you want
