That's the point.  It seems to be mainly the GNU version of libc which has them.
If you have GNU libc installed for your system, you're OK.  If you use the
native one (the one which comes with the manufacturer's version of cc) it may
well be missing.

Which is, of course, not 'standard' except on those sytems.  The only standard
is the ANSI one, and that doesn't mention it, so library manufacturers are
free to not include nonstandard functions.

Ours seems to be missing.

I've seen several over the years.  Perhaps it's become more common now,
but until another ANSI/ISO standard comes out including it or a replacement
the only portable way to go is to ignore it.
