+Subject: [PATCH] Fix time_t vs long int mismatches.
+
+Old gnulibs used randomly either time_t or long int, with a compile-time
+assert to ensure sizeof(time_t) <= sizeof(long int). This is not the
+case on x32 where the machine word is 32 bit, yet time_t is 64 bit to
+be able to handle dates after 2038.
+
+This is not relevant for modern versions of gnulib which has rewritten
+this code, but, sadly, findutils 4.4.* uses an embedded copy of ancient
+gnulib.
