FIX: to kernel/include/a.out.h

[utzoo!decvax!ucbvax!dist2]

	In diff, there is a call to a macro N_BADMAG, which I found in
	the VAX a.out.h, but not in the supplied one.

These changes should be made to kernel/include/a.out.h:

	diff kernel/include/a.out.h.old kernel/include/a.out.h:
	23a24,36
	> /*
	>  * Macros which take exec structures as arguments and tell whether
	>  * the file has a reasonable magic number or offsets to text|symbols.
	>  */
	> #define	N_BADMAG(x) \
	>     (((x).a_magic)!=A_MAGIC1 && ((x).a_magic)!=A_MAGIC2 && \
	>      ((x).a_magic)!=A_MAGIC3 && ((x).a_magic)!=A_MAGIC4 && \
	>      ((x).a_magic)!=A_MAGIC5 && ((x).a_magic)!=A_MAGIC6)
	> 
	> #define	N_TXTOFF(x) \
	> 	((x).a_magic==A_MAGIC5 || (x).a_magic==A_MAGIC6 ? \
	> 	 sizeof (struct ovlhdr) + sizeof (struct exec) : sizeof (struct exec))
	> 

They should be applied to all tapes written before 10/5/81.
