  error C2876: 'Base::fun' : not all overloads are accessible

Please refer to the sample code in the "More Information" section for details.

STATUS
======

Microsoft has confirmed this to be a bug in the Microsoft products listed at the
beginning of this article.


MORE INFORMATION
================

The compiler does not allow a private base class member name to be injected into
a derived class by a using declaration even though the derived class is declared
as a friend class of the base class.

Steps to Reproduce Behavior
---------------------------

The following sample code demonstrates the bug:

  //test.cpp
  // compiler option needed: none
  class Derived;
  class Base
  {
  friend class Derived;
  void fun(void);
  };

  class Derived : public Base
  {
  protected:
  using Base::fun;
  };
