Microsoft didn't institute this.  John Reiser did when he was at Bell Labs.
This feature has been in UNIX since Version 7, and has been documented since
System V.  It is also in the ANSI C draft standard.

Wrong.  You can't say

	#ifdef FOO || BAR

to include code if FOO or BAR is defined, but you can say

	#if defined(FOO) || defined(BAR)

This is useful, and has in fact been used in a number of programs.
