Subject: Changes == 0 to <= 0 for node id test
X-Git-Url: http://git.nguyen.vg/gitweb/?p=SXSI%2Flibbp.git;a=commitdiff_plain;h=5979c34ae2455997903c8b2cc43a53f4cc13353c

Changes == 0 to <= 0 for node id test
	* negative node-ids are special values that denote dummy nodes
	or errors, since valide nodes are positive, refusing the root
	with <= 0 rather than == 0 tells the compiler that the value
	of the id is (strictly) positive in the subsequent code,
	allowing the compiler to perform more agressive optimisations.
