Comment (by viboes):

 The definition of


 {{{
     template <>
     struct chrono_numeric_limits<float,true> {
         static BOOST_CHRONO_LIB_CONSTEXPR float lowest()
 BOOST_CHRONO_LIB_NOEXCEPT_OR_THROW
         {
             return -(std::numeric_limits<float>::max) ();
         }
     };
 }}}

 where

 {{{
 #if defined( BOOST_NO_CXX11_NUMERIC_LIMITS )
 #define BOOST_CHRONO_LIB_CONSTEXPR
 #elif defined(_LIBCPP_VERSION) &&  !defined(_LIBCPP_CONSTEXPR)
   #define BOOST_CHRONO_LIB_CONSTEXPR
 #else
   #define BOOST_CHRONO_LIB_CONSTEXPR BOOST_CONSTEXPR
 #endif
 }}}


 Please, could you tell me which macro is defined for the library that I
 can check so that BOOST_CHRONO_LIB_CONSTEXPR is defined as


 {{{
   #define BOOST_CHRONO_LIB_CONSTEXPR

 }}}
 ?
