Anatoly recently introduced two new AVR categories into GCC: avr25 and
avr35.  They should be though of as avr2.5 and avr3.5: while they
share almost everything with avr2 and avr3 respectively, they add the
MOVW instruction.  This is e.g. the case for all recent ATtinys: they
do have MOVW but they don't feature a hardwar multiplier.

I believe the change to __AVR_HAVE_MUL__ is part of that change.
Anatoly might correct me if I'm wrong.

Never trust an operating system you don't have sources for. ;-)
