How about...

   #define VECTOR(signame) \
   void SIG_ ## signame (void) __attribute__ ((interrupt)); \
   void SIG_ ## signame (void)

This way it would get closer to Atmel's datasheets. Instead of...

   SIGNAL(SIG_ADC)
   {
        // ...
   }

one could simply use:

   VECTOR(ADC)
   {
        // ...
   }

I'm aware that there's already _VECTOR(x) macro, but as it's internal to 
avr-libc, it shouldn't cause any confustion.
