I am not sure whether the correct one is OPT_Wcxx0x_compat or
OPT_Wc__0x_compat. You cant test which one works just using
-fdiagnostics-show-option, this should print the option that generated
that warning. If it doesn't print -Wc++0x-compat, then you got it
wrong. (Or also using  -Werror=c++0x-compat as suggested).

I hope GCC will last for another two decades but yes. We can add
-Wcompat=* or -Wstd-compat=* in 2020. That is actually a good
argument. :-)
