From 331d9e3b91c21b3c592882ac90df0c6210868d8c Mon Sep 17 00:00:00 2001
From: Joel Sherrill <joel.sherrill@OARcorp.com>
Date: Fri, 8 Nov 1996 20:08:52 +0000
Subject: Added asserts for unhandled conditions which need to result in error
 statuses being returned to gnat runtime in order for it to raise use_errors. 
 This was needed to identify the places in gnat's runtime which needed to be
 addressed.
