+       cycle-check integer overflow fixup.
+
+       * cycle-check.h: Remove now-inaccurate comment about the files
+       you need to include first.  You don't need to include any files
+       other than the usual config.h.
+       Include <inttypes.h> and <stdint.h> if available, for uintmax_t.
+       Remove 'struct stat;' not needed since we know sys/stat.h has
+       been included by dev-ino.h.
+       (struct cycle_check_state): Change chdir_counter to uintmax_t,
+       not size_t, since it isn't limited by object sizes.
+       Change magic from long unsigned int to int; that's good enough
+       for our use.
+       * cycle-check.c (is_zero_or_power_of_two): Renamed from
+       is_power_of_two, to reflect better what it really does.
+       All uses changed.  Arg is now uintmax_t, not unsigned int
+       (it should have been unsigned long int -- that was a bug).
+       (cycle_check): Check for integer overflow in cycle count,
+       and report a cycle if that happens, as it must be a cycle
+       by this point.
+
        backupfile.c rewrite to avoid arbitrary limits on lengths of
        numeric backup extensions.

+
        * addext.c: Remove; no longer needed.
        * Makefile.am (libfetish_a_SOURCES): Remove addext.c.
        * backupfile.h (addext): Remove decl.

        new numbered backup name has the same length as the old.
        Also, use xmalloc rather than malloc, so that the caller
        needn't worry about memory exhaustion.
