Hi!

dup3(2) is now specified by POSIX.1-2024.  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!
Alex

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.
