Comment (by chris.cooper@…):

 std::numeric_limits<Number>::min() and std::numeric_limits<Number>::max()
 are not constant expressions unless c++11 is specified, so a better fix is

 {{{
 #if !defined(BOOST_NO_LIMITS) && !defined(BOOST_NO_CXX11_CONSTEXPR)
 template <class Number> struct complement_traits {
    BOOST_STATIC_CONSTANT(Number, min =
 std::numeric_limits<Number>::min());
    BOOST_STATIC_CONSTANT(Number, max =
 std::numeric_limits<Number>::max());
 };
 #else
 [SNIP] All of the other template definitions for complement_traits,
 complement_traits_aux, etc.
 #endif
 }}}
