32 * Revision 1.1.1.1 1999/06/14 22:02:09 donut
33 * Import of d1x 1.37 source.
35 * Revision 1.12 1994/06/17 15:22:46 matt
36 * Added pragma for Error() for when NDEBUG
38 * Revision 1.11 1994/03/07 13:22:14 matt
39 * Since the Error() function has 'aborts' set in pragma, we do a jmp
40 * to the function rather than call.
42 * Revision 1.10 1994/02/17 12:37:15 matt
43 * Combined two pragma's for Error(), since second superseded the first
45 * Revision 1.9 1994/02/10 18:02:53 matt
46 * Changed 'if DEBUG_ON' to 'ifndef NDEBUG'
48 * Revision 1.8 1994/02/09 15:18:29 matt
49 * Added pragma saying that Error() never returns
51 * Revision 1.7 1993/10/19 12:57:53 matt
52 * If DEBUG_ON not defined, define it to be 1
54 * Revision 1.6 1993/10/15 21:40:39 matt
55 * Made error functions generate int3's if debugging on
57 * Revision 1.5 1993/10/14 15:29:22 matt
58 * Added new function clear_warn_func()
60 * Revision 1.4 1993/10/08 16:16:47 matt
61 * Made Assert() call function _Assert(), rather to do 'if...' inline.
63 * Revision 1.3 1993/09/29 11:39:07 matt
64 * Added Assert() macro, like the system one, but calls Error()
66 * Revision 1.2 1993/09/27 11:47:03 matt
67 * Added function set_warn_func()
69 * Revision 1.1 1993/09/23 20:17:46 matt
