Don't see it here, either. OTOH, it's not easy to see that it isn't the
case.
Line 205 marks the end of the #ifdef _EVERYBODY_AND_HIS_DOG_SOURCE
macros, which start at lines 8 & 9.  I'd like to see an editor where
you can tell that without reading every line in between...(not to start
a war over editors, mind you!)
This is where I see a reason for stuff like:
#endif /* XOPEN/GNU/POSIX */
A comment after every endif (like glibc does) is rather absurd, though.

And it seems to me that usually the non-macro-protected code goes on
top, making it clearer what is ANSI...

Not to say that it's wrong, just that it could be clearer.
