I wasn't suggesting a problem with the current distribution, that -D is
a simple workaround (but expecting a gnuXX to work isn't - not everything
is gcc), but in your earlier message you quotes the 2023a NEWS:

     The two new macros are transitional aids planned to be removed in a
     future version, when C99 or later will be required.

and my point was just that that future version probably ought to be
rather distant future, not next year sometime (or even the next few years
after that).

It might be worth adding a "common issues" file (with some rational name,
not that) that people can look in, if things don't simply work first time,
if for nothing else, to avoid needing to send queries to this list.
