This is true.  But unless I missed something, the code checks if the
-Wno-error=... option can be used, but doesn't make DEPRECATED a noop if it
cannot be used.  If that is the desired behaviour (and I think it is) then
some more simple work is needed on top of that.  I volunteer to take care of
it.
