Erm... sed is just as crossplatform as Ant :) but, really, I didn't mean to argue. I'm used to compile with patches, besides, since signed RSLs are no longer an option, (so far I understand it) - that doesn't matter, if I'll compile for production, I'll probably have much more patches to apply, so that's fine.
By the way, is there any decision on how SDK is compiled? I would be willing to write a scons build (I am not an expert in scons, but I liked what I saw, and that would be an interesting learning exercise). I know, I'd need to start another thread, if there's not already, sorry for the flame :)
