The size argument is based upon using printf() and not Write().  The
program Loren posted is a good example of how to make a small 'C' program!

Please note that I made zero attempts at optimizing for size or speed while
Loren made every attempt.  Also note that my post was not meant as a challenge,
but just as an illustration of how you get smaller code WITHOUT trying.  It was
the most minimal program example, which K&R defines as:

main() {
	printf("Hello, world\n");
}

Of course, no offense taken.
