	The compiler should complain about the following because
	the "," operator works with expressions, and "return"
	is NOT an expression (ie. it doesn't have a value).

	is OK because "exit()" is a function call and therefore
	has a value.  (though I am willing to guess that it would
	be invalid if "exit()" was defined as a function returning
	"void".
