Proposed resolution:

This wording is relative to N3797.

1. Edit 21.3.4 [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; }
     };
     […]
   }
