--- Comment #2 from Jonathan Wakely <redi at gcc dot gnu.org> ---
I think we should just change it to check __cpp_lib_concepts, which is only
true for C++20 anyway:
-#if __cplusplus <= 201703L
+#if ! __cpp_lib_concepts
That is the right condition for using __clamp_iter_cat, iter_value_t,
iter_difference_t and iter_reference_t.
