Oops.  Libraries built for avr4 also can't be used on attiny2313
and the like.  Until this "half-enhanced" ;) AVR core (with MOVW,
without MUL) is supported properly, these devices will have to be
moved from avr4 to avr2.  This is sub-optimal (MOVW not used),
but GCC 4.0 release is too close for more significant changes...
