Arduino mit Eclipse

Hallo zusammen,
ich habe nach vielen Stunden Eclipse (Galileo) für Arduino configuriert. Der Testcode lt. Tutorial war auch OK. Habe nun diesen Code versucht, das allseits bekannte "Blink":

/*
 * main.c
 *
 *  Created on: 09.04.2010
 *      Author: Willi
 */

#include <avr/io.h>
#include <WProgram.h>
 int ledPin = 13;

 int main(void) {
                 pinMode(ledPin, OUTPUT);

       for(;;) {
               digitalWrite(ledPin, HIGH);   // set the LED on
               delay(1000);                  // wait for a second
               digitalWrite(ledPin, LOW);    // set the LED off
               delay(1000);                  // wait for a second
             }
 }

Dann werden folgende Meldungen in der Console angezeigt:
