Make 4.2.1 here with gcc 7.2.1 and I get tons of build warnings on my
3.18.y tree on my laptop, but my build machine running Fedora (make
4.2.1 and gcc 7.2.1) I get no build warnings at all.

I've given up trying to track it down for my laptop, something is
preventing the compiler flag from being added to the gcc command line,
and I don't care anymore...
