Even though it is probably there for a reason, I'd like
to try to continue with the build. But I cannot see
what c++ switch prevents warnings from being treated as
errors.

Please advise
many thanks

It is -Werror.

seems to have no effect here:

or is it being overwritten by other -W options?

No, -Werror is the *cause* of that condition.  See the info(1) page.
