So it seems the following snippet

seems like the right thing to do, as you said.
That version would need updating when we add -std=c2x (once there's a C2x
working draft with features being added to it). If you use std=c* instead
of separate std=c9* and std=c1* you'd avoid needing such a change - but
then of course it would cover -std=c++* for C++.
I know, that why I used the current form. Admittedly it's a maintenance
problem (likely to be forgotten in the future). If we add in -ansi, we
can just as well add -std=c++* (thus -std=c*), too.
I guess that's the safest option overall, unless Jonathan has objections
from a C++ standards perspective.
