The interrupt vectors are defined in:
/usr/local/avr/include/avr/iom128.h
but the numbers are off-by-one for some reason.
TWI and TWO_WIRE are there too...although I had
some trouble following your question's path
from ADC to there...
Other interesting tidbits can be found in the
compiler header files as well.
