   6 //  MACRO:         BOOST_NO_USING_DECLARATION_OVERLOADS_FROM_TYPENAME_BASE
   7 //  TITLE:         using declaration function overloads from a typename base
   8 //  DESCRIPTION:   The compiler will not accept a using declaration
   9 //                 that brings a function from a typename used as a base class
  10 //                 into a derived class if functions of the same name
  11 //                 are present in the derived class.
