Looking at the assembly, you probably want:

--cut here--
int test (int a, int b, int c)
{
  unsigned r = a + b;

  if (r < (unsigned) a)
    return 1;
  else if (r > c)
    return 1;

  return 0;
}
--cut here--

gcc-4.8.2 -O2:

test:
        addl    %esi, %edi
        movl    $1, %eax
        jc      .L2
        xorl    %eax, %eax
        cmpl    %edx, %edi
        seta    %al
.L2:
        rep ret

Please note how the compiler is able to generate jc without compare insn.
