Those pieces of code are pretty much the same.

If you look at the arduino source code you'll see:

setup();
for (;;) {
 loop();
 if (serialEventRun) serialEventRun();
}

(I'm not sure what serialEvent() does)

I don't think you can 'overload' the main function declaration. Also note that the main function calls init, which e.g. configures the timers, so millis() etc. will work.
