Update.
1998-05-14 13:25  Ulrich Drepper  <drepper@cygnus.com>

	* inet/netinet/in.h: Add defines for multicast.
	Reported by Jeremy Hall <jhall@UU.NET>.

	* stdlib/stdlib.h: Add prototypes for __setenv and __unsetenv.
	* sysdeps/generic/putenv.c: Use __setenv and __unsetenv, not setenv
	and unsetenv.  Optimize _LIBC case.
	* sysdeps/generic/setenv.c: Prevent unnecessary memory leaks.
	Define functions with leading __.

	* time/tzfile.c: Correct handling of global variables daylight,
	timezone, and tzname.
	* time/tzset.c: Likewise.
	* timezone/Makefile (tests): Add tst-timezone.
	* timezone/tst-timezone.c: New file.

1998-05-14 10:35  Ulrich Drepper  <drepper@cygnus.com>

	* timezone/asia: Update from tzdata1998d.
	* timezone/australasia: Likewise.
	* timezone/europe: Likewise.
