In a recent article, I suggested some changes to Dick Dunn's ANSI C version
of IEFBR14.  I originally suggested that exit(0) could be replaced
by return(0), and the setlocale() could be dropped, eliminating the need
for include files.  But then I said that return(0) was non portable;
it had to be EXIT_SUCCESS, which required an include file.

Apparently, Gordon Burditt (gordon@sneaky.lonestar.org) can read
better than I can, since he pointed out in mail that the section on exit()
in the C standard makes a special case for zero as successful
termination.  So:

int
main(void)
{
	return 0;
}

is all you need for IEFBR14.

As penance, I suppose I should read the standard again, but
I've already lost as much hair as I can afford.
