From efa77952c8f99a5a6e0233e935a24ef6bad495b9 Mon Sep 17 00:00:00 2001
From: Ian Lance Taylor <ian@airs.com>
Date: Mon, 8 Jan 1996 22:02:36 +0000
Subject: [PATCH] 	* ieee.c (ieee_write_debug_part): Change return type
 to boolean. 	If there is a SEC_DEBUGGING section, get the contents of the
 debug 	information part from it. 	(ieee_set_section_contents): Store the
 contents of a SEC_DEBUGGING 	section in memory. 
 (ieee_write_object_contents): Check ieee_write_debug_part return.
