  33  *      Definitions for accessing mach-o headers.
  34  *
  35  * NOTE:        The functions prototyped by this header only operate againt
  36  *              32 bit mach headers.  Many of these functions imply the
  37  *              currently running kernel, and cannot be used against mach
  38  *              headers other than that of the currently running kernel.

  40  * HISTORY
  41  * 29-Jan-92  Mike DeMoney (mike@next.com)
  42  *      Made into machine independent form from machdep/m68k/mach_header.h.
  43  *      Ifdef'ed out most of this since I couldn't find any references.
