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.
