Update.

2004-08-11  Ulrich Drepper  <drepper@redhat.com>

	* time/tzset.c (tzset_internal): Add new parameter which is
	nonzero if called through tzset.  Use TZDEFAULT name including
	name comparison if the new parameter is zero.  This means implicit
	tzset calls will not cause files to be opened and read by tzfile.c
	all the time.

2004-08-11  Jakub Jelinek  <jakub@redhat.com>

	* time/tzfile.c (__tzfile_read): Free transitions only if it will
	not be reused.
