(What's new in 4.8 is it being included in -Wall, which is why I never noticed it in 4.7). > It affects Boost more than most code because of the prevalent use of > concept checks and static assertions which are usually implemented > using typedefs but only conditionally compiled. I've seen spews of that warning for other large projects, such as clang or wxWidgets, not just boost.
