46 * Each kernel has a major and minor version number. Changes in
47 * the major number in general indicate a change in exported features.
48 * Changes in minor number usually correspond to internal-only
49 * changes that the user need not be aware of (in general). These
50 * values are stored at boot time in the machine_info strucuture and
51 * can be obtained by user programs with the host_info kernel call.
52 * This mechanism is intended to be the formal way for Mach programs
53 * to provide for backward compatibility in future releases.
54 *
55 * [ This needs to be reconciled somehow with the major/minor version
56 * number stuffed into the version string - mja, 5/8/87 ]
57 *
58 * Following is an informal history of the numbers:
59 *
60 * 25-March-87 Avadis Tevanian, Jr.
61 * Created version numbering scheme. Started with major 1,
62 * minor 0.

69 * Version number of the kernel include files.
70 *
71 * This number must be changed whenever an incompatible change is made to one
72 * or more of our include files which are used by application programs that
73 * delve into kernel memory. The number should normally be simply incremented
74 * but may actually be changed in any manner so long as it differs from the
75 * numbers previously assigned to any other versions with which the current
76 * version is incompatible. It is used at boot time to determine which
77 * versions of the system programs to install.
78 *
79 * Note that the symbol _INCLUDE_VERSION must be set to this in the symbol
80 * table. On the VAX for example, this is done in locore.s.
