Thanks Till, I tried that, but the compiler complains that my lcd.c (not
'foo', but lcd.. ;-) uses undeclared functions and defines, despite in
main.c (let's call the main C source file this way, I took care to
include my lcd.h statement UNDER all other usual includes.


main.c :
-------
#include <stdio.h>
#include <stdlib.h>
#include <avr/io.h>
#include <avr/interrupt.h>
#include <avr/signal.h>
#include <avr/delay.h>

#include "lcd.h"    <----------- my file with LCD related routines
(well, only the prototyptes of course)



Am I supposed to copy all the "regular" includes at the top of lcd.h as
well ?
