Maybe not the smallest one, but still:

int ev, k8, le;

void
vp (int d5)
{
  if (ev != 0)
    ev = 0;

  while (k8 != 0)
    {
      k8 = 0;
      while (k8 != 0)
        {
          k8 = ev;
          while (ev != 0)
            {
              ev = 1;
              while (ev != 0)
                le = 0;
              ++ev;
            }
        }

      le = ev;
      while (ev != 0)
        {
        qd:
          for (k8 = 0; k8 < 1; ++k8)
            {
              k8 /= ev;
              le /= le / ((le + 1) / (k8 != 0));
              if (le != 0)
                {
                  ++k8;
                  ev /= k8;
                }
            }
          ++ev;
        }
      ev = 0;
    }

  while (ev != 0)
    {
      while (le != 0)
        {
          for (k8 = 0; k8 < 1; ++k8)
            {
              k8 /= le + 1;
              if (k8 != 0)
                goto qd;
              while (le < 1)
                ++le;
            }
          ++le;
          ++le;
        }

      if (k8 != 0)
        return;
    }

  vp (d5);
}
