+       test-sys_socket: mark variables as used more readably
+       * tests/test-sys_socket.c (main): Mark otherwise unused variables
+       as "used" explicitly via (void) statement casts.  This is more
+       readable than using them in an artificial return expression.
+       Suggestion from Bruno Haible.

        Avoid some more warnings from "gcc -Wwrite-strings".
