avr6 definitely does not show up in my "Known MCU names:" list. It ends at 
avr5!? :-(

And my gcc is 

Configured with: ../gcc-4.3.3/configure --target=avr --prefix=/usr/local/avr 
--enable-languages=c --disable-libssp --disable-shared --disable-libada 
--disable-libssp --disable-nls --with-dwarf2 --with-gmp=/usr/local

I need this on Sun Solaris and doubt anyone is offering ready-to-use packages 
for this platform. So I have to build from sources.

Anyone had success building the chain from sources and got avr6 support?

Thanks,
