| 28 | * Revision 1.1.1.1 1998/09/22 21:05:30 wsanchez | |
| 29 | * Import of Mac OS X kernel (~semeria) | |
| 30 | * | |
| 31 | * Revision 1.1.1.1 1998/03/07 02:25:45 wsanchez | |
| 32 | * Import of OSF Mach kernel (~mburg) | |

| 34 | * Revision 1.1.4.2 1997/02/07 12:12:35 barbou | |
| 35 | * Fixed the defines (some were missing the "MACH_" prefixes). | |
