As long as I'm not completely lost, those values are often passed on the command
line via `-D`. Wouldn't a random \[aq] interfere with shell quoting and result in
hard to find bugs and unexpected bahavior? So is it really a good idea to present
those values in such a way in the manpage? Or am I simply underestimating the
intelligence of the readers? :-)
Hi Tom,
As \[aq] renders as aprostrophe/single-quote "'" the value can be "1993'09L"
quoted if required.
I would expect these values to most often be set and tested in headers and
sources, mainly from systems, compilers, or libraries, to indicate support of
certain features or enable their interfaces to be defined.
I would expect these to be rarely set nowadays in hopes of enabling otherwise
disabled features required to build a package or application, more likely to
change or disable undesired interfaces, and instead expect them to be configured
by compiler options e.g. -std=gnu23 and/or in library headers, and tested by
application or package sources.
