    This  turns  out  to  also	be  the  case  for  Amdahl   UTS   (in
contradiction to the April ANSI C draft and every  other  Unix	system
I've worked on.) In fact, crt0.s under UTS explicitly says 'exit  with
0 status if main returns'.  Sigh.  Probably  the  distributed  munch.c
should be modified to call exit instead of return to  account  for  as
many (brain-damaged) environments as possible.
