The Arduino IDE performs some "magic" before it starts the gcc compiler, among which is adding this:

#include <WProgram.h>
int main(void)
{
   init();
   setup();    
   for (;;)
      loop();        
   return 0;
}

So don't let you become fooled by fancy ideas. What's inside init() you can find by looking into:
