C++ "using" overload bug in 1.1 and mainline

[Mumit Khan <khan at xraylith dot wisc dot edu>]

Someone just pointed this out in comp.lang.c++ ... almost verbatim from
D&E I believe.

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

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

ns-overload-bug.cc:12: cannot adjust access to `void A::f(int)' in `class B'
ns-overload-bug.cc:11:   because of local method `void B::f(long int)' with same name
