I don't understand the problem.  I thought the original problem was that
the C front end doesn't accept the switch.  So I tell you how to get it
to accept it.  Then you say the problem is that the C front end accepts
the switch?

The correct place to modify C front end options is the big table in
c-opts.c; nowhere else.
