//  MACRO:         BOOST_NO_UNREACHABLE_RETURN_DETECTION
//  TITLE:         detection of unreachable returns
//  DESCRIPTION:   If a return is unreachable, then no return
//                 statement should be required, however some
//                 compilers insist on it, while other issue a
//                 bunch of warnings if it is in fact present.
