Besides your code missing linefeeds so it's barely readable: sorry,
GCC code optimization is nothing we could do anything about. We are
*only* dealing with the standard library that is frequently used
together with AVR-GCC.
About AVR-GCC, you'd have to talk to the GCC developers. However, AVR
is a minor target only there. The most competent person to talk to
about AVR-GCC's optimizations is probably stil Georg-Johann Lay
though. He implemented a lot of improvements in that area in the past
years.
