That's not a valid C++ program, even in C++23 after <stdatomic.h> is added. For C++23 it needs to be _Atomic(int) because in C++ _Atomic is not a type qualifier (unlike in C). Clang supports the _Atomic qualifier in C++ mode, but that's non-standard. This code is not portable to any compiler except Clang, and is no longer even portable to Clang when using G++ in C++23 mode. I suppose we could enable the contents of <stdatomic.h> for the non-strict -std=gnu++XX modes before C++23, but you'd still need to adjust your program to use _Atomic(int) instead of _Atomic int. Why not just write it in proper C++, using std::atomic<int> or the atomic_int typedef instead? _______________________________________________ devel mailing list -- devel@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to devel-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/devel@xxxxxxxxxxxxxxxxxxxxxxx Do not reply to spam on the list, report it: https://pagure.io/fedora-infrastructure
