From 89ccd2b16f496ea7d898ef66fa2e47db5a8d5ca2 Mon Sep 17 00:00:00 2001
From: Albert Cheng <acheng@hdfgroup.org>

Subject: [svn-r10829] Purpose: Bug fix

Description:
Various system or software (e.g. MPE) will print some diagnosis
messages to stderr that cannot be suppressed.  They messed up
the output matching. Installed the STDERR_FILTER() to remove
all these messages.

Platforms tested:
LANL flash.

Misc. update:
