--- Comment #16 from Jonathan Wakely <redi at gcc dot gnu.org> ---
We could also just add:

#if __cplusplus > 202002L
  template<floating_point _Tp>
    void
    nexttoward(_Tp, long double) =3D delete;
#endif


The existing overloads would be preferred for float, double, long double and
integral types, so this would only be chosen for extended floating-point ty=
pes.=
