posixtm-tests: port to buggy compiler Problem reported by Simon Josefsson in <http://lists.gnu.org/archive/html/bug-gnulib/2012-06/msg00246.html>. * modules/posixtm-tests (Depends-on): Add stdint. * tests/test-posixtm.c (struct posixtm_test.t_expected): Now of type int_least64_t, not int64_t, both because that's what INT64_C returns and because int_least64_t works even on 72-bit hosts. (T): Use INT64_C on constants outside the traditional int range, to work around compiler bug noted by Simon.

+	* tests/test-posixtm.c (struct posixtm_test.t_expected):
+	Now of type int_least64_t, not int64_t, both because that's

 	mktime: fix integer overflow in 'configure'-time test
 	* m4/mktime.m4 (gl_FUNC_MKTIME): Do not rely on undefined behavior
 	after integer overflow.  Problem reported by Rich Felker in
