[Cc:ing two developers who know a lot about documentation and standards]


Hello Maya,

thanks for your patch!

However, i'm not sure i understand.

  https://www.iso.org/standard/74528.html

seems to indicate the existence of a brand new standard called

  ISO/IEC 9899:2018
  Information technology -- Programming languages -- C

but i failed to find any evidence that an official standard
called ISO/IEC 9899:2017 might exist.

Can you provide a reference to such a standard?


Even if it does exist (or if you suggest s/17/18/), note that mandoc
does not aim to provide macro arguments for all the standards under
the sun.  A new major revision of the C programming language is no
doubt an excellent candidate for addition, but i would still welcome
solid evidence that it will actually see substantial use in practice.

Does the NetBSD base system implement the C18 standard, and are you
going to update all the relevant NetBSD manual pages to refer to it,
where appropriate?  How many manual pages, approximately, do you
expect will reference it in NetBSD in the short term?

Note the in OpenBSD, the only references even to -isoC-2011 are
in mdoc(7) and groff_mdoc(7), and

  https://man.openbsd.org/?query=St%3DC11&apropos=1&manpath=NetBSD-7.1
  https://man.openbsd.org/?query=St%3DC11&apropos=1&manpath=FreeBSD-11.1

only return minimal additional content, which implies to me that even
the addition of -isoC-2011 may have been premature.

Thanks again,
  Ingo
