Get the patches from the WinAVR project's CVS. See the README file that
comes with them. It explains the patch naming convention; some patches won't
be applicable to your system (i.e. MinGW/Windows only). The patch filenames
are prefixed with a number, so they are applied in order in which they are
numbered. Use binutils 2.17 (plus patches) and gcc 4.1.2 (plus patches) and
avr-libc 1.4.6. The patches in WinAVR also include the patches for the
ATmega256x devices.

And get in contact with Colin O'Flynn (CCed). As he is a regular on the
Dalhousie campus, he should be able to help you out in this direction. ;-)
