Bison version 2.2 has been released.
To make GPC work with it requires some minor changes. Patch attached, details in the ChangeLog entry.
Bison 2.2 also has a new feature:
: * %require "VERSION" : This specifies that the grammar file depends on features implemented : in Bison version VERSION or higher.
Since we actively use some newer (2.0 and/or 2.1) features of Bison, we actually should use this check, to avoid users even trying with older Bisons which cannot work. OTOH, since the check is new in 2.2, we can't "%require 2.1", so by using this check we would needlessly (ATM) require Bison 2.2.
What should we do? Perhaps wait until 2.2 is more widespread, then require it?
