Oh, I certainly wouldn't deny that. :-)

Yes, the tendency to handle far too many items as 16 bits (the
sizeof(int) on that machine) when 8 bits would suffice is one of the
major issues the AVR-GCC users have with the compiler.  If we could
really find someone to improve that, we'd probably even catch up with
the rather famous IAR compiler (that right now generates about
10...20 % tighter code, at a price of some four-digit USDs per
license...).
