The PIO port is connected to the LEDS on the board. Each bit in the PIO port corresponds to an LED. So if you change the one line to read: 

IOWR_ALTERA_AVALON_PIO_DATA(LED_PIO_BASE, count & 0x03);

You should get two leds blinking ... oh the excitement. :) Amazing how rewarding the blinking of a little light can be.
