Nice work. I'm all for it :)

You header file includes many "fixes" similar to what is present in my
own, custom header file(s) - it would be nice if these changes could
be included in avr-libc proper.

I noticed that your ISR() macro is defined as:


   #define ISR(vector, ...)                       \
      void vector (void) ISR_BLOCK __VA_ARGS__;   \
      void vector (void)


Will this allow for the following syntax:


   ISR(VectorName, ISR_NOBLOCK)
   {
   // Code goes here
   }


Wouldn't this set both the 'interrupt' and 'signal' attributes at the
same time?

Regards,
Brix
