        * src/atomic.cc (atomic_flag_test_and_set_explicit): Add
        static_cast from base to derived.
        (atomic_flag_clear_explicit): Same.
        * include/bits/atomic_2.h (__atomic2::atomic_flag): Public derivation.
        Remove value type constructor.
        * include/bits/atomic_0.h (__atomic0::atomic_flag): Same.
        * include/std/future (_Future_state): Use ATOMIC_FLAG_INIT to
        initialized the atomic_flag member.
