[BZ #1774] 

2005-11-03  Ulrich Drepper  <drepper@redhat.com>
	[BZ #1774]
	* sysdeps/posix/getaddrinfo.c (gaih_inet): Don't use simple
	gethostbyname2 lookup if AI_V4MAPPED|AI_ALL is set.

	* sysdeps/posix/getaddrinfo.c (gaih_inet): Avoid alloca when possible
	while looking for scope delimiter.
	Some pretty printing.
