From 7c31742a07c7fa311b0c78c598066944db1ca900 Mon Sep 17 00:00:00 2001
From: Peter Eisentraut
Date: Fri, 29 Aug 2008 13:02:33 +0000
Subject: Remove all traces that suggest that a non-Bison yacc might be
 supported, and change build system to use only Bison.  Simplify build rules,
 make file names uniform.  Don't build the token table header file where it is
 not needed.
