    The function has been officially removed in ISO C11.  This opportunity
    is used to also remove it from the GNU feature list.  It is now only
    available when explicitly using an old ISO C, Unix, or POSIX standard.
+   GCC defines _GNU_SOURCE when building C++ code and the function is still
