| | 29 | * Import of Mac OS X kernel (~semeria) |
| | 30 | * |

| | 32 | * Import of OSF Mach kernel (~mburg) |
| | 33 | * |
| | 34 | * Revision 1.1.4.2 1997/02/07 12:12:35 barbou |
| | 35 | * Fixed the defines (some were missing the "MACH_" prefixes). |

| | 38 | * Revision 1.1.4.1 1996/11/29 16:59:20 stephen |
| | 39 | * nmklinux_1.0b3_shared into pmk1.1 |
| | 40 | * Contents of sys/ioctl.h. Prefixed the definitions with "MACH" to avoid |
| | 41 | * conflicts with UNIX servers. |
