I'd recommend reducing the -O3 to -O2 since gcc has bugs which will make -O3 sometimes break utterly and in many cases it slows stuff down anyway.
Not to mention that -O3 doesn't guarantee faster code. In fact, lots of things end up much slower, because -O3 generates much larger code, which cocks up the use of the instruction cache.
I think I have a play with this over the xmas break. Providing it all go okay and I got a lot of movies to watch ;)
