Sorry, miscommunication.... The latest CVS is correct. The avrfreaks 
distribution is an older build and (obviously) changes were made 
between then and now. 

If you use the avrfreaks windows distribution with gcc 3.2 *and* you 
also get the latest iom128.h and sfr_defs.h from CVS (because they're 
very useful), then there is (I think) one change you will need to 
make to the latest sfr_defs.h to make it "backwards-compatible" with 
the avrfreaks distribution to get interrupts to link correctly. (IIRC 
this has to do with the definition of _VECTOR). That's the caveat.
