C-Prolog finds one solution at a time, UNSW looks for all solutions to a
goal.  C-Prolog (and many others) only give you a chance to ask for more
solutions at the top level if there are free non-anonymous variables in
your query.  An easy way to show that C-Prolog was finding both solutions
in the original program is

	?- a([]), write(hello), nl, fail.

Count the number of 'hello's.
