    vec.h: Fix GCC build with -std=3Dgnu++20 [PR98059]

    Apparently vec.h doesn't build with -std=3Dc++20/gnu++20, since the
    DR2237 r11-532 change.
    template <typename T>
    class auto_delete_vec
    {
    private:
      auto_vec_delete<T> (const auto_delete_vec<T> &) =3D delete;
    };
    which vec.h uses is invalid C++20, one needs to use
      auto_vec_delete (const auto_delete_vec &) =3D delete;
    instead which is valid all the way back to C++11 (and without =3D delete
    to C++98).

            * vec.h (auto_delete_vec): Use
            DISABLE_COPY_AND_ASSIGN(auto_delete_vec) instead of
            DISABLE_COPY_AND_ASSIGN(auto_delete_vec<T>) to make it valid C+=
