  25  *      Definitions for accessing mach-o headers.
  26  *
  27  * NOTE:        The functions prototyped by this header only operate againt
  28  *              32 bit mach headers.  Many of these functions imply the
  29  *              currently running kernel, and cannot be used against mach
  30  *              headers other than that of the currently running kernel.

  32  * HISTORY
  33  * 29-Jan-92  Mike DeMoney (mike@next.com)
  34  *      Made into machine independent form from machdep/m68k/mach_header.h.
  35  *      Ifdef'ed out most of this since I couldn't find any references.
