 * $Revision: 1.12 $
 * $Author: matt $
 * $Date: 1994/06/17 15:22:46 $
 *
 * Header for error handling/printing/exiting code
 *
 * $Log: error.h $
 * Revision 1.12  1994/06/17  15:22:46  matt
 * Added pragma for Error() for when NDEBUG
 * 
 * Revision 1.11  1994/03/07  13:22:14  matt
 * Since the Error() function has 'aborts' set in pragma, we do a jmp
 * to the function rather than call.
 * 
 * Revision 1.10  1994/02/17  12:37:15  matt
 * Combined two pragma's for Error(), since second superseded the first
 * 
 * Revision 1.9  1994/02/10  18:02:53  matt
 * Changed 'if DEBUG_ON' to 'ifndef NDEBUG'
 * 
 * Revision 1.8  1994/02/09  15:18:29  matt
 * Added pragma saying that Error() never returns
 * 
 * Revision 1.7  1993/10/19  12:57:53  matt
 * If DEBUG_ON not defined, define it to be 1
 * 
 * Revision 1.6  1993/10/15  21:40:39  matt
 * Made error functions generate int3's if debugging on
 * 
 * Revision 1.5  1993/10/14  15:29:22  matt
 * Added new function clear_warn_func()
 * 
 * Revision 1.4  1993/10/08  16:16:47  matt
 * Made Assert() call function _Assert(), rather to do 'if...' inline.
 * 
 * Revision 1.3  1993/09/29  11:39:07  matt
 * Added Assert() macro, like the system one, but calls Error()
 * 
 * Revision 1.2  1993/09/27  11:47:03  matt
 * Added function set_warn_func()
 * 
 * Revision 1.1  1993/09/23  20:17:46  matt
 * Initial revision
