+       maint: detect usage(1) and other suspicious exits
+       * top/maint.mk (sc_prohibit_magic_number_exit): New rule.

+
+       timespec: long-to-int truncation could make timespec_cmp malfunction
+       * lib/timespec.h (timespec_cmp): Do not interpret a difference of
+       a multiple of 2^32 nanoseconds as no difference.

+       fprintftime: wrap macro code argument in "do {...} while(0)"
+       * lib/strftime.c (cpy) [FPRINTFTIME]: The second argument to the
+       cpy macro must be a statement that can be followed by a semicolon.
+       Now that the else clause contains a comment and is hence longer
+       than one line, I require curly braces.  That in turn requires
+       that we wrap this code block in the standard do...while(0).
+
+       fprintftime: remove stray semicolon from previous change
+       * lib/strftime.c (cpy) [FPRINTFTIME]: Remove trailing semicolon.
+
+       fprintftime: avoid a warning about ignored fwrite return value
+       * lib/strftime.c [FPRINTFTIME]: Include "ignore-value.h".
+       (cpy) [FPRINTFTIME]: Ignore fwrite failure, even though technically,
+       that is unsafe.
+       * modules/fprintftime (Depends-on): Add ignore-value.
+
        exclude: avoid an unwarranted warning
        * lib/exclude.c (excluded_file_name): Initialize "rc" before switch.
