Update.
1999-04-28  Andreas Jaeger  <aj@arthur.rhein-neckar.de>

	* nss/digits_dots.c: Use inet_aton to parse IPv4 numbers.
	This allows e.g. gethostbyname to accept "10.1234".
	Reported by Alexander V. Lukyanov <lav@long.yar.ru> [PR libc/1096].

	* nss/test-netdb.c (test_hosts): Add test for gethostbyname and
	non quad IPv4 numbers.

	loaded shared object with all loaded objects.  Initialize l_ino
