/*	set.h\r
\r
	The following is a general-purpose set library originally developed\r
	by Hank Dietz and enhanced by Terence Parr to allow dynamic sets.\r
	\r
	Sets are now structs containing the #words in the set and\r
	a pointer to the actual set words.\r
\r
	1987 by Hank Dietz\r
	\r
	Modified by:\r
		Terence Parr\r
		Purdue University\r
		October 1989\r
\r
		Added ANSI prototyping Dec. 1992 -- TJP\r
