	29	* File: kern/mach_header.h
	30	*
	31	* Definitions for accessing mach-o headers. This header wraps the
	32	* routines defined in osfmk/mach-o/mach_header.c; this is made clear
	33	* by the existance of the getsectcmdsymtabfromheader() prototype.
	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.
	39	*
	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.
