People told you that your code relied on undefined behaviour. I can see that that is not the best answer from your perspective, but to me it does not seem like an unreasonable answer. If you would like a specific warning, then present a specific case of code which is undefined, and suggest what warning it should issue. Also indicate which warning options you tried; for example, did you try -Wstrict-aliasing? Ian
