C4127 is also awkward. As it gives warnings for some common idioms. It refers to conditional expressions being constant.

These warnings can be annoying, but they aren't useless. They do find bugs.

I agree that 4127 can help you find bugs. But I can't think of any situation where 4511 or 4512 will help you find a bug. If you actually try to call an inaccesible copy constructor or assignement operator, then the compiler (correctly) fails to compile it. Thats why I used the word "awkward" rather than "useless" for 4127. I'll happily be proved wrong though. Sam ****************** This e-mail has been sent from Imagination Technologies Limited.
