Uh, maybe
    /* Remember first to #define signed or #define unsigned. */
    IsUnsigned(a)
    #ifdef signed
            int a;
    #else
            unsigned a;
    #endif
    {
    #ifdef signed
            return 0;
    #else
            return 1;
    #end
    }
Doesn't sound like a job that a programmer would want.....
