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.
