Modified Files:
	getaddrinfo.c 
Log Message:
- - - -- -- A U T O M A T I C   C H E C K I N -- -- - - -
	(gaih_addrtuple): Change type of addr to avoid casts.
	(gethosts): Removed.
	(gethosts2): Renamed to gethosts.  Make it usable for family !=
	AF_UNSPEC.  Fix AI_V4MAPPED.
	(gaih_inet): Remove use of old gethosts.  Always use what used to be
	gethosts2.  If entry is found, try to use the same NSS module's
	getcanonname_r function.  Use gethostbyaddr for AI_CANONNAME only
	if getcanonname_r was not available.  Fix filtering of AI_V4MAPPED
	addresses.  Numerous cleanups.
