It should be provided when the POSIX feature test macros are used. Are there any POSIX.1-2024 macros yet, or is there any ongoing work for that? Have a lovely night!

I started working on conform tests for ISO C23 [1]. It is my goal to work on updating conform for C23 and then moving to POSIX.1-2024. That will involve updating the feature macros like __USE_GNU to use new ones defined under _POSIX_C_SOURCE==202405L || _XOPEN_SOURCE==800.

Thanks! Please let me know when you're done with C23; we should document that in the manual pages. Have a lovely night!
