This is not a bug, its a feature.  MAX is not a number, its an expression.
Thus, the evaluation of MAX is a long int.  The first printf only prints
the high word of the long int MAX.  The second printf properly casts the
long int to an int and prints the correct result.  Try:

	printf("3: %ld\n", MAX);
