No invalidation would be happening now, merely a note in the coming standard that the %b in printf(1) would (might) be removed in a later version of

version of the standard isn't likely for at least another decade (the
coming one isn't finished yet, and that's not the next that counts here, and later issues that are merely corrections (TCs) don't count either). [As a reference for timelines, the current POSIX standard is from 2008,
though a couple of TCs have followed it - that's 15 years already
between versions.]

Thank you for this detailed clarification.  It's good to know that the 2013,
2016 and 2018 versions/revisions of POSIX actually don't count.

That's not what he said.

Huh, quite frankly, this makes me confused a bit. Now I'm wondering what actually are the 2013, 2016 and 2018 revisions of POSIX? I'd really appreciate further clarification, but please keep in mind that I'm referring to the HTML stuff downloadable for free from The Open Group, such as the 2017/2018 revision linked below.

Is the stated IEEE Std 1003.1 the right stuff at all? The web page says that it also has a couple of TCs integrated, so I'd guess that it is the right stuff, which the link below also suggests by explaining IEEE Std 1003.1 further.

Quite frankly, all this is confusing, and even more is confusing why such standards aren't available for free to anyone interested in that matter. That's ridiculous, IMHO.
