Yes, you are right. If we make decision to use "lib per device" patch shoul be 
added to HEAD only.

What minimal required version of GCC should be chosen for avr-libc 2.0? 

If 4.4  then we need to add a patch to the GCC faster, GCC 4.4 it is planned to 
release in January. 

If  "lib per device" will be added to GCC 4.5 and avr-libc 2.0 will require GCC 
4.5 then the new toolchain will be released only after one year, it is very 
late. 

I prefer variant avr-libc 2.0 / GCC 4.4. But I assume that Dmitry would object, 
he prefers not to restrict the GCC version for using with avr-libc. In this 
case, I agree with the option to add the "lib per device" patch in avr-libc 1.8.
