parser: add const to parser token table

From: Steven Whitehouse
Date: Mon Jul 21 2008 - 10:52:21 EST

This patch adds a "const" to the parser token table. I've done an
allmodconfig build to see if this produces any warnings/failures and the
patch includes a fix for the only warning that was produced.
