+       * These changes should make it unnecessary to call tzset from
+       Scheme after modifying the TZ environment variable, even if the
+       system date facilities cache the value.
+       * stime.c (setzone, scm_localtime): added comments.
+       (tzset): don't define a noop tzset macro if HAVE_TZSET not defined.
+       (setzone): don't call tzset.
+       (restorezone): call tzset only if HAVE_TZSET is defined.
+       (scm_tzset): don't define if HAVE_TZSET not defined.  Change the
+       doc string to indicate that this procedure isn't likely to do
+       anything useful.
+       (scm_localtime, scm_strftime, scm_mktime): call tzset if
+       LOCALTIME_CACHE is defined.
