--- Comment #2 from Harald van Dijk <harald at gigawatt dot nl> ---
The warning is suppressed because it is supposedly from a system header (even
though clearly, that is not the case) and including -Wsystem-headers on the
command-line shows:

$ gcc-run/bin/g++ -std=c++11 -c test.cc -Wsystem-headers
