Yeah, it's the third one that many me notice this.  It's Linux/NPTL specific.
Only old systems won't have it.  I'm not even sure how good our support for
LinuxThreads is nowadays.  I occasionally hear about it, but I suppose
maybe even those targets stuck in LinuxThreads already have up-to-date headers.

If gnulib replaces it, then it won't be there.  If it doesn't, then the
fallback would be necessary for old systems.  I'd be totally fine with
waiting to hear if someone actually stumbles on this, as the fix is quite
trivial.  I just mention it so it doesn't pass up as an inadvertent change.
