How can I call (not define) a function with a variable number of arguments in C?

Question

Is there any way to make this code shorter?

long call_f(int argc, long *argv) {
  switch (argc) {
    case 0:
      return f();
      break;
    case 1:

Which seems to work, yet scare people. It's not guaranteed cross-platform or portable, but it seems to be workable on a couple of platforms, at least. ;)
