I haven't looked at the code, but based on some historical emails on this list it seemed like multiple <compilerArgument> tags were the way to go. One possible fix would be to take away the quoting of these arguments, but I'm not sure if this wouldn't create some new unintended side-effects.
It certainly sounds like this is something that could stand to be improved.
