You can use the corresponding -Wno-* option to remove it.

There's no much point in voting on this or other bugs: What is needed is
someone brave enough to tackle the problem and figure out how to solve it in a
way that is accepted by the maintainers.

Comment #6 is as relevant today as it was 6 years ago. But perhaps simple cases
can be detected without any CCP or VRP in the FE. Someone needs to figure it
out.
