 *	Functions for maintaining the Lst allTargets. Target nodes are
 * kept in two structures: a Lst, maintained by the list library, and a
 * hash table, maintained by the hash library.
 *
 * Interface:
 *	Targ_Init 	    	Initialization procedure.
 *
 *	Targ_End 	    	Cleanup the module
 *
 *	Targ_List 	    	Return the list of all targets so far.
 *
 *	Targ_NewGN	    	Create a new GNode for the passed target
 *	    	  	    	(string). The node is *not* placed in the
 *	    	  	    	hash table, though all its fields are
 *	    	  	    	initialized.
 *
 *	Targ_FindNode	    	Find the node for a given target, creating
 *	    	  	    	and storing it if it doesn't exist and the
 *	    	  	    	flags are right (TARG_CREATE)
 *
 *	Targ_FindList	    	Given a list of names, find nodes for all
 *	    	  	    	of them. If a name doesn't exist and the
 *	    	  	    	TARG_NOCREATE flag was given, an error message
 *	    	  	    	is printed. Else, if a name doesn't exist,
 *	    	  	    	its node is created.
 *
 *	Targ_Ignore	    	Return TRUE if errors should be ignored when
 *	    	  	    	creating the given target.
 *
 *	Targ_Silent	    	Return TRUE if we should be silent when
 *	    	  	    	creating the given target.
 *
 *	Targ_Precious	    	Return TRUE if the target is precious and
 *	    	  	    	should not be removed if we are interrupted.
 *
 *	Targ_Propagate		Propagate information between related
 *				nodes.	Should be called after the
 *				makefiles are parsed but before any
 *				action is taken.
 *
 * Debugging:
 *	Targ_PrintGraph	    	Print out the entire graphm all variables
 *	    	  	    	and statistics for the directory cache. Should
 *	    	  	    	print something for suffixes, too, but...
