--- Comment #16 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
bison 1.35 doesn't, and that is what has been used last time.
Is even %define api.pure full (vs. %pure_parser) supported in much older bi=
son
versions?  Maybe 1.875 is the oldest people do use in real-world, not sure.
Requiring bison 3 or later only is unacceptable right now.=
