It's only used in static assertions, so they can just be omitted if the trait isn't available. libstdc++-v3/ChangeLog: PR libstdc++/114891 * include/std/generator: Check feature test macro before using is_pointer_interconvertible_v. (cherry picked from commit 1fbe1a50d86df11f434351cf62461a32747f9710)
