It's in stock 4.3BSD, i think (i don't have a pristine copy of 4.3 to
tell from right now). There was a point where we had ENDIAN defined
as either BIG or LITTLE, and the code looked like
#if ENDIAN == BIG ...
but that went away, and now it's BYTE_ORDER defined as either
BIG_ENDIAN or LITTLE_ENDIAN (or pdp, the crooked endian...).
I'll append our current endian.h for the vax.
