Proposed resolution:

Add in [memory], Header <memory> synopsis missing declarations as shown below:

// 20.8.11 Class unique_ptr:
template <class X> class default_delete;
template<class T> struct default_delete<T[]>;
template <class X, class D = default_delete<T>> class unique_ptr;
template<class T, class D> class unique_ptr<T[], D>;

template<class T, class D> void swap(unique_ptr<T, D>& x, unique_ptr<T, D>& y);

template<class T1, class D1, class T2, class D2>
bool operator==(const unique_ptr<T1, D1>& x, const unique_ptr<T2, D2>& y);
template<class T1, class D1, class T2, class D2>
bool operator!=(const unique_ptr<T1, D1>& x, const unique_ptr<T2, D2>& y);
template<class T1, class D1, class T2, class D2>
bool operator<(const unique_ptr<T1, D1>& x, const unique_ptr<T2, D2>& y);
template<class T1, class D1, class T2, class D2>
bool operator<=(const unique_ptr<T1, D1>& x, const unique_ptr<T2, D2>& y);
template<class T1, class D1, class T2, class D2>
bool operator>(const unique_ptr<T1, D1>& x, const unique_ptr<T2, D2>& y);
template<class T1, class D1, class T2, class D2>
bool operator>=(const unique_ptr<T1, D1>& x, const unique_ptr<T2, D2>& y);

Moved to Tentatively NAD Editorial. The editor has adopted the fix.

Related to 296. Some unique_ptr signatures are missing from the synopsis in [memory].
