[avr-chat] gcc/libc 4.0

[Balbo Ezio]

I have a problem about avr-gcc and/or avr-libc (i think).

On the new pc I have installed avr-gcc/libc 4.0
but .hex file DO NOT workink on the board.

The ouptut from avr-gcc/libc/ 3.3 on an 
old PC are OK and I don' have any problem 
on the microcontrolled board.

I don't know how to fix the problem, I need to
continue the development on the new PC.

Here is the avr-gcc/libc version of the old pc (OK)
>>>>>>>>>>>>>> PC OLD NO PROBLEM  :-)
