Description

There are several files under the GPL with BISON expection license.

However none of them are 'GPL-2.0-or-later' today, all of them are 'GPL-3.0-or-later' now, and none of them have '... version 1.24 of Bison' and all of them have '... version 2.2 of Bison'.

Search done by using: grep -i -e "of bison" -r . for quick file listing,

and by: grep --before=20 --after=20 -i -e "bison" -r . | grep --after=2 --before=20 -i exception to list the whole license blocks (with the GPL part), but it contains few false positive results (matched code instead of license block)
