Update.
2004-09-26  Ulrich Drepper  <drepper@redhat.com>

	* sysdeps/posix/getaddrinfo.c (getaddrinfo): Remove incorrect
	requirement on socktype and protocol.
	(gaih_inet): If numeric port number is given, return records for all
	possible socket types.
	* posix/tst-getaddrinfo2.c: New file.
	* posix/Makefile (tests): Add tst-getaddrinfo2.  [BZ #358]
