Proposed resolution:

This wording is relative to N4023 in regard to fundamental-ts changes.

1. In fundamental-ts, change [mods.util.smartptr.shared.const] p34 as indicated:

   template <class Y, class D> shared_ptr(unique_ptr<Y, D>&& r);
   

   -34- RequiresRemarks: This constructor shall not participate in overload resolution unless Y* shall beis compatible with T*.

   -35- Effects: Equivalent to shared_ptr(r.release(), r.get_deleter()) when D is not a reference type, otherwise shared_ptr(r.release(), ref(r.get_deleter())).

   -36- Exception safety: If an exception is thrown, the constructor has no effect.

[ 2015-02, Cologne ]

Unanimous consent.

Addresses: fund.ts

The proposed resolution for LWG 2399 doesn't apply cleanly to the Fundamentals TS, but the issue is still present.
