// 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.
