* $Source: f:/miner/source/misc/rcs/error.h $
* $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* Combined two pragma's for Error(), since second superseded the first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
