I'm not denying that there is lots of room for -Os code size improvements, but from the http://embed.cs.utah.edu/embarrassing/ results GCC doesn't perform that bad in comparison with other compilers (gcc 3.4 best, then icc and then gcc 4.5), and all the results there were from -Os compilations across the different compilers.
