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