From 4a5f83b8f0cf0d6899940f1940ac1f63bac847ca Mon Sep 17 00:00:00 2001
From: Pedro Vicente Nunes <pvn@hdfgroup.org>
Date: Tue, 28 Jun 2005 11:25:42 -0500
Subject: [svn-r10994] Purpose: bug fix

Description:
when 2 objects were not comparable, the final print information for the non verbose mode printed "0 differences found"


Solution:

replaced instead with a Summary message that says
"Some objects were not comparable"


Platforms tested:
linux
solaris
