That question rather goes to Ted.  To the best of my knowledge, he's
considering that move, too, but that implies to me it might still be
some way to go.

By now, we only benefit from the generic DWARF2 work that has been
done in GCC, i. e. as far as I know, nobody has ever done anything
specific for the AVR for this to happen.  So what you're seeing is
basically a by-product of the IA32 (aka. i386) world moving away from
stabs to DWARF2 as their default debugging format, which is obviously
the driving force behind all this.  (That's the good thing about GCC:
there are so many things that are completely architecture-independant,
so all the supported archs automatically benefit from work done on
some mainstream arch.)

It's probably best if you asked that on the GCC developers mailing
list, I guess (or maybe the embedded GCC list -- I think Eric is
subscribed there; I'm not).
