Although I think it is good to make it work the same on every platform, I do think that changing it to *match* what the most used compiler (GCC) on our most used platform (Linux/AMD64) is what the new behaviour should be like — not something that "looks best". I think that's what Laruence was trying to say as well. It causes the least amount of BC breaks for our users. cheers, Derick
