        (auto_ptr): _M_ptr changed to void*.
        (suto_ptr::get): Cast _M_ptr to element type.
        (auto_ptr::auto_ptr(auto_ptr<Tp1>)): Test implicit convetsion.
        (auto_ptr::~auto_ptr): Use this->get() instead of _M_ptr.
        (auto_ptr::operator*): Likewise.
        (auto_ptr::operator->): Likewise.
        (auto_ptr::release): Likewise.
        (auto_ptr::reset): Likewise.
        (auto_ptr::auto_ptr(auto_ptr_ref)): Initialize from __ref._M_release.
        (auto_ptr::operator auto_ptr_rev<_Tp1>): Updated.
        Define nested auto_ptr_ref unless _GLIBCPP_RESOLVE_LIB_DEFECTS.
        Define operator=(auto_ptr_ref) if _GLIBCPP_RESOLVE_LIB_DEFECTS.
