_XOPEN_SOURCE_EXTENDED is obsolete (it existed in SUSv1, but not
subsequent standards). _XOPEN_SOURCE >= 500 produces the same
effects as (_XOPEN_SOURCE && _XOPEN_SOURCE_EXTENDED). Modifying
the SYNOPSIS of various ages that contain:
_XOPEN_SOURCE\ >=\ 500 ||
_XOPEN_SOURCE\ &&\ _XOPEN_SOURCE_EXTENDED
to just:
_XOPEN_SOURCE\ >=\ 500
This has the following benefits:
a) Simplifying the SYNOPSIS by removing ancient
historical information.
b) Preventing users from being misled into using
_XOPEN_SOURCE_EXTENDED in new source code.
