   * Add a test case (tests/0021.{in,out,sh}) to verify that tbl-dctrl
     handles UTF-8 correctly.
      - As it requires the C.UTF-8 locale, build-depend on libc-bin >= 2.13
+  * Since mblen is unnecessarily marked warn_unused_result with
+    _FORTIFY_SOURCE, (see bug #674917), causing spurious warnings upon
+    mblen initialization calls, switch to using mbrlen in tbl-dctrl.c (a
+    good idea in any case).
