Details:

Changes from 2013-05-03 introduce bug in:
/usr/avr/include/util/delay.h
With gcc-4.8 I get:
usr/avr/include/util/delay_basic.h:83:2: error: '__ticks' may be used 
uninitialized in this function [-Werror=maybe-uninitialized]
  __asm__ volatile (
  ^
/usr/avr/include/util/delay.h:248:10: note: '__ticks' was declared here
  uint8_t __ticks;
          ^
lto1: all warnings being treated as errors
make[1]: *** [/tmp/ccVIU3hR.ltrans8.ltrans.o] Błąd 1

Maybe there is an error in /usr/avr/include/util/delay.h ?
_delay_loop_1(__ticks) should be run always or it should be in braces with:
else    {
         __ticks = (uint8_t)__tmp;
    _delay_loop_1(__ticks);
}
