I don't see the license in neither generated parsers, but in both
generated parsers there is the same nice exception note, the
`special exception` to `distribute that work under terms of your
choice, so long as [the nesting work is not a parser generator
itself] or a modified version thereof as a parser skeleton`.

My parser generated using Bison 2.3+apple states the
generated parser as (sic) `is free software and you can […]
under the terms of the GNU General Public License version
2, or (at your option) any later version.
