Just to let you know.  I have just soldered an ATmega2561 to plug into an old 
Kanda STK300 board so I'll be in a position to check out some 256x related 
changes to the tool set.

Also, I noticed that there is no include files for the new parts.  That must be 
part of the effort to support new parts.

Has anyone thought of parsing the XML files that are supplied with AVR Studio 
to generate the include files.  I played with the PugXML parser available at 
thecodeproject.com and have so far been able to generate signal macros from the 
interrupt vector definitions.

I think it can be made to work, but some of the macro names may have to change 
as a result, for example, instead of SIG_INTERRUPT0 it generates SIG_INT0.  But 
I think that backwards compatibility can be accomplished using macros like:

An alternative would be to code in some additional substitution rules while 
parsing the XML files.  Anyone have thoughts on this?
