Thanks for pointing this out.

For firefox/fennec compiling, according comments in this thread (Quote from Taras Glek: "I tried 4.5 -O2 and it's actually faster than 4.3 -Os.") with 4.5, can we have some changes on their default flags, say using -O2 instead of -Os (also check how much the size will increase), then see what's the performance regression?

Meanwhile, 1.0 update will still use 4.4.2, and now in Trunk:Testing, 4.5 is for 1.1 Oct release, even though we should nail down it asap, but we still have some time on this.

Are we migrating to GCC 4.5 in Trunk? If so, please at least provide
also a GCC 4.4 package. Because there is "massive performance
regression" in GCC 4.5 impacting firefox (thus fennec in MeeGo):
