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.
