+ nstrftime, time_rz: Avoid using an obsolete Autoconf macro.
+ Reported by Mike Gran <spk121@yahoo.com> in
+ <https://lists.gnu.org/archive/html/bug-gnulib/2021-01/msg00067.html>.
+ * lib/time-internal.h: Test HAVE_STRUCT_TM_TM_ZONE, not HAVE_TM_ZONE.
+ * lib/time_rz.c: Likewise.
+ * lib/nstrftime.c: Set and test HAVE_STRUCT_TM_TM_ZONE, not
+ HAVE_TM_ZONE.
+ * m4/nstrftime.m4 (gl_FUNC_GNU_STRFTIME): Update comments.
