I know, but Thiago said he hadn't seen it actually do any warnings. And 
I agree with him that I haven't seen it warn about integer types.

In one of my customer projects I ported their project to Windows and got 
thousands of the double to float warnings, which is why I mentioned that 
it certainly does do something.
