--- Comment #6 from Marc Glisse <glisse at gcc dot gnu.org> --- (In reply to Paolo Carlini from comment #5) > Detail: normally we just pass around tsubst_flags_ts, no complain & tf_error > to bool, etc. Those flags are not available in c-family, this is not the first place where we pass a bool in this case.
