You don't need that init stuff... Where did You find that? Try this: 

# include "altera_avalon_pio_regs.h"# include "system.h"# include <stddef.h>
int main(void) {
while (1)
  {
    usleep(1000*1000);
    IOWR_ALTERA_AVALON_PIO_DATA(USER_LEDS_BASE, 1);
    usleep(1000*1000);
    IOWR_ALTERA_AVALON_PIO_DATA(USER_LEDS_BASE, 0);
  }
  return 0;
}
