   In other words, it relies on:
	   awk '' files...
   to exit with a nonzero status if not all of the files exist.
   This seems to be what "old" awk does.
   However, "new awk" (/bin/nawk on SunOs 4.1) prints nothing and exits
   with status 0 in this case, and GNU awk prints a usage message.

... and people keep claiming that awk is portable.  :-)

Well, you could use perl to test if all of the files are present.... no,
wait....  :-)
