From e995f3a1ac2ff5b74c1be3670b548c80dd995b46 Mon Sep 17 00:00:00 2001
From: Joel Sherrill <joel.sherrill@OARcorp.com>
Date: Thu, 6 Aug 1998 15:27:08 +0000
Subject: Changed debug enable macros to support individually enabling
 different types of debug information.

Removed call to rtems_panic which was based on checking a variable which
was no longer being set.
