I don't agree here. It's a hint for compilers and developers that the address of such variables won't be needed (and cannot be taken) to enable whatever optimizations are possible knowing this. Somewhat like inline functions, it's not a forced optimization, just a useful hint that shouldn't hurt if used wisely. Besides, cassette decks are not dead yet :) -- Adrien Mazarguil 6WIND
