Here we go.

We used to generate the part descriptions for AVR-Ada by a Perl script  
that read the corresponding avr-libc io files and generated Ada code.  I  
recently changed to Ted Roth's Python script and generate the Ada specs  
directly from Atmel's XML "Partdescriptionfiles".  As a result many  
interrupts (and some pins) changed their names and I had to change my  
application code accordingly.  I considered this a good thing as the code  
has (almost*) the same interrupt identifiers now as the data sheets.  But  
then AVR-Ada has practically no code base out there and I don't have to  
care much about compatibility.


I would welcome if avr-libc accepted the interrupt names as given in data  
sheets.  One less source of confusion.  For some time the old names should  
still be supported as alias names.


* the interrupt short names in the XML files sometimes contain funny  
characters that cannot be part of an identifier.  I replace all of comma,  
blank, or slash to underscores in the Python script.  I don't know why  
Atmel created interrupt names containing these characters in the first  
place...
