Yes. If we release from revision r2473 it will work with gcc-5.1, not trunk.

If we release from last revision r2474, it will work with gcc trunk, not 

So, we need to change avr-libc to build with all versions of gcc.

Lib directories and startup file names are decided in bootstrapping. But valid 
compiler is checked in configure. So, auto detection of compiler and configure 
libs/startups will require infrastructure change.

Do you have any input on this?

My in-progress patch will work with additional user options, not auto detection.
I could submit this by early next week.
