However if the change distracts a human reader from understanding the intent, code quality is reduced.

I hope this makes sense to our users. Or might be we could just decrease the warning level in every TBB header. I would buy that argument if it were Intel's official view.

We might now start waiting for GCC users to come and require us fixing warnings beyond -Wall.Since GCC does not support warning suppression by pragmas, the code clutter will theninclude GCC-specific C4512 Example : void callAWarning(int a) { //some stuff without a variable } And when you compile : Warning 2 warning C4100: 'a' : unreferenced formal parameter Now how to resolve this The problem you can get is that calling the same function from two contexts might end up calling the same final overrider with different default values: struct base { virtual void
