Re: MSVC sillywarnings -- more?

That is not silly at all, and do catch mistakes -- though too bad it can't
guess where we used a constant intentionally...


Some versions create different names for class/struct so ignoring this may
lead to cryptic linker errors...

My tuning file looks like below. I normally compile at W3 switching to W4
only occasionally. So most tuning is actually to elevate levels...
