Package: byacc
Version: 20100216-1
Severity: wishlist
Tags: patch
bison allows for posix yacc emulation via a yacc directive in the yacc file, and
also via a command line switch.
This patch turns the directive and command line
option into noop's for byacc, since byacc is designed to be posix yacc
compatible anyway. This allows for better compatibility with yacc sources
written for bison. Note this patch applies after all the other patches I've
submitted.
