* time/tst-mktime2.c (N_STRINGS): Remove.
(set_timezone): New function.
(spring_forward_gap): Call it. Use FAIL_EXIT1.
(mktime_test1): Report localtime failure and check errno value.
Use TEST_COMPARE.
(irix_6_4_bug, bigtime_test): Use TEST_COMPARE.
(do_test): Remove alarm call. Use set_timezone and array_length.
