Proposed resolution:

This wording is relative to N3797.

  1. Edit 23.15.3 [meta.help] as indicated:

    namespace std {
      template<class T, T v>
      struct integral_constant {
        static constexpr T value = v;
        typedef T value_type;
        typedef integral_constant<T,v> type;
        constexpr operator value_type() const noexcept { return value; }
        constexpr value_type operator()() const noexcept { return value; }
      };
      […]
    }
