We do define __EXTENSIONS__, this is not the issue. We define
_XOPEN_SOURCE to 600 on all systems, because that is the highest value
specified by any X/Open spec today. The system may not support all of
the latest Posix features; this is not problem because we
autoconfiscate them.

The problem really only occurs if somebody thinks they need to define
_XOPEN_SOURCE to some other value; the compiler will then complain.
