No, so I think the change is certainly not appropriate in that form.
The porting_to.html, in particular porting_to.html#warnings-as-errors
has detailed explanation on what actually changed etc., so I think we just
want one short sentence that certain C warnings are now errors and refer
to particular porting_to.html#warnings-as-errors for details.
Because the above shortcut is certainly not true.
