Just noticed that we can simplify life further.  Instead of:

we could use using declarations to quickly pick up the names:

#ifdef BOOST_NO_NAMESPACE_FOR_STDC
 #include <cstddef>
 #include <cstdlib>
 #include <cmath>
 namespace std {
  using ::size_t; using ::ptrdiff_t;
  using ::div_t; using ::ldiv_t;
  using ::abs; using ::labs;
  using ::srand; using ::div; using ::ldiv; using ::rand;
  using ::acos; using ::asin; using ::atan; using ::atan2; using ::ceil;
  using ::cos; using ::cosh; using ::exp; using ::fabs; using ::floor;
  using ::fmod; using ::frexp; using ::ldexp; using ::log; using ::log10;
  using ::modf; using ::pow; using ::sin; using ::sinh; using ::sqrt;
  using ::tan; using ::tanh;
 }
#endif
