From 04049103c8d246d5dbc6c6d62e12b2f462208abb Mon Sep 17 00:00:00 2001
From: "jan.nijtmans" <nijtmans@users.sourceforge.net>
Date: Tue, 7 Aug 2012 14:58:34 +0000
Subject: add 3 testcases for "dde poke", only active with --enable-symbols (we
 need a "dde poke" server for that, which is now built into tcldde14g.dll, but
 not in tcldde14.dll)
