/*	Bit patterns to allow fast answers to set questions about classes.
	The classes in the inpdef are given as single letters; the array
	class[] contains a bit pattern for each letter, with those bits set
	that correspond to the lint class meaning of the letter.

	This facility is used through the macro  is_class(inpdef_var, CL_XXX)
