Why not? We already do many workaround in avr-libc because of issues
with dealing with GCC, such as the long release cycles. If we get this
fix into AVR GCC, it might be available in 4.3.0, which could still be
2-3 months out. If we miss the window, it will have to be in 4.4, which
is certainly a lot longer.
