Current values are:

__POSIX_VISIBLE 199009
__POSIX_VISIBLE 199209
__POSIX_VISIBLE 199309
__POSIX_VISIBLE 199506
__POSIX_VISIBLE 200112
__POSIX_VISIBLE 200809
__POSIX_VISIBLE 201402

and anticipated release date is 2022 from FAQ

	https://www.opengroup.org/austin/faq.html

	Q8. Where is the schedule for draft development?

so could use:

__POSIX_VISIBLE >= 202202 /* FIXME when POSIX Issue 8 released */
