Empty body declaration - Rebuild of the Debian archive with clang

"Empty body declaration" build failure(s) — clang 3.1

-Wempty-body warning is enabled by default which is not the case with gcc.
So, the following code will fail with clang but build with gcc:

int main() {
    if (1);
}

clang -Werror -c plop.c
gcc -Werror -c plop.c
