(void)s;

Results:
----------------------------------------------------------------------
$ clang -std=c11 -Weverything -O3 test.c && ./a.out

5 warnings generated.

clang version: clang version 3.9.0 (trunk 268228)
I guess the 2nd and 5th warnings intended to warn about missing braces around
"2" only.
