Gentlemen,
I encountered the follwing problem:
In one of your example files, the file <avr/sleep.h> is not found by the compiler.
from the scetch:
// We need these includes to program the WDT
#include <avr/sleep.h>
Then I have the following (verbose) compiler output.

C:\Users\Axel\Documents\Arduino\sketch_feb01b\sketch_feb01b.ino:18:23: fatal error: avr/sleep.h: No such file or directory
As far as I can see the avr directory is not in the include paths.
I assume this path should be included automatically and is not related to a library that I have to include.
What do I overlook?
