  As far as I can tell by googling, _POSIX_SOURCE, despite the leading
underscore, is in fact a user-land feature test macro that it is up to each
individual application to decide whether to switch it on or not according to
whether the application itself is compliant or not.

  IOW, the system headers should have nothing to say about it at all, although
they may well want to react to it if it is defined at the time they are

Can't think of a witty .sigline today....
