For those who want to see test their C skills, determine what this
program does.  (Send me email if you do not want to run it on your system.
It was sent to me by a friend and appears to be harmlessly doing only
putchar() invocations but I cannot guarantee it.)

 * LEAST LIKELY TO COMPILE SUCCESSFULLY:
 * Ian Phillipps, Cambridge Consultants Ltd., Cambridge, England
 * 
 * An appropriate program for December 25th, this consists primarily of
 * calls to main() combined by a lot of the ternary conditional (?:)
 * operators. Have you ever seen a more forceful return? The judges note
 * that this program looked like what you would get by pounding on the
 * keys of a type writer at random.
