microsoft C considered stupid

[Rick Genter]

     Actually, the defined() preprocessor function does provide a convenience
over #ifdef in one specific case:

	#if defined(VAX730) || defined (VAX750) || defined (VAX780)
		< code which is included when any of the three symbols
		  are defined >
	#endif /* defined ... */

This is a royal pain to accomplish with #ifdef:

	#undef KLUDGE
	#ifdef VAX730
	#define KLUDGE
	#endif /* def VAX730 */

	#ifdef VAX750
	#define KLUDGE
	#endif /* def VAX750 */

	#ifdef VAX780
	#define KLUDGE
	#endif /* def VAX780 */

	#ifdef KLUDGE
		< code which is included when any of the three symbols
		  are defined >
	#endif /* def KLUDGE */

Alternatively, you have to include the code three times.
