just to be clear, what i suggested as a better solution is for any implementation of target specific stuff consists of at least two implementations, one generic and one specialize. This way, it will not break any build, while give the specific target the implementation the developer really wants. The actual implementation could be templates, or weak/strong symbols Naturally, any better solution is welcome. Let's put to rest any argument on Is_target_xxx or ifdef. Sun
