It can be ignored, I think -- after all, the presence of that
extension won't cause any miscompiles, but will merely result in a
failure to diagnose a potential problem should the user change some
code that uses those macros. So as long as enough active Emacs
developers use non-ancient versions of gcc, there's really no
problem...
