Report a bug to the gcc-bug mailing list, I guess.  I don't see
anything wrong with the code it flags here.

Note that the complaints are about the calls of ARG with an unsigned
type as its argument, while `flags' is an int.  I don't see how could
that be wrong, but maybe declare `flags' unsigned and see if that
helps.
