Well I'm trying with avr-gcc 3.4.3 to use -minit-stack=0x10FA (I'd like 
to keep away 5 bytes: I do some sort of circular buffer to have up to 4 
reboot 'cause' + the current one) and when I look at main.sym, I see 
that __stack is still at 0x10FF.

However using (&__bss_end)+1 is okay, I made some tests and I'm able to 
get back my bytes after reboot.
