That's an ancient standard; the current one is here:

http://pubs.opengroup.org/onlinepubs/9699919799/utilities/getconf.html

It does not mention the macros you asked about. But it's also
describing the getconf utility, not the unistd.h header. The latter is
here:

http://pubs.opengroup.org/onlinepubs/9699919799/basedefs/unistd.h.html

and I don't see anything about the above macros. For what it's worth,
even the old version corresponding to the page you linked doesn't seem
to specify them:

http://pubs.opengroup.org/onlinepubs/7908799/xsh/unistd.h.html
