--- Comment #1 from Jonathan Wakely <redi at gcc dot gnu.org> ---
We also retain the pre-LWG280 homogeneous overloads:

  template<typename _Iterator>
    inline _GLIBCXX17_CONSTEXPR bool
    operator=3D=3D(const reverse_iterator<_Iterator>& __x,
               const reverse_iterator<_Iterator>& __y)
    { return __x.base() =3D=3D __y.base(); }

I don't have a demo, but this might be non-conforming for cases where we
compare reverse_iterator<T> and something convertible to that type.=
