Expression result unused - Rebuild of the Debian archive with clang

"Expression result unused" build failure(s)
clang 3.4

clang triggers a warning on this useless usage of the define. The -Werror causes the failure.

#define bar(int) (1)

void foo() {
    bar(2);
}

With gcc, this warning is only displayed with -Wall.
