+Problem reported by Khem Raj in:
+https://lists.gnu.org/r/bug-gnulib/2024-01/msg00045.html
+* lib/posixtm.c (posixtime): Pacify clang 18 by converting bool to int.
+Arguably this is a bug in draft C2x, since the non-pointer args to
+ckd_add should promote just like any other expressions do;
+but that’s not clang’s fault.
