No, I thought of doing that in my tree.  But the problem is then someday
someone will go to use that second arg and they'll be very surprised when
it doesn't work right.  Seems to me it's better to be incomplete (ie not
have the prototytpe) that to seem complete, but have a broken
implementation.

I haven't looked, but do any of the other m68k ports have a longjmp
implementation that can be used?  Maybe sys/systm.h should include
machine/systm.h and have the kernel longjmp prototyped there.
