Yes I had. I do want implicit conversion in some of those cases.

I'd be happy to add a cast, but there is no way in C/C++ to say: "cast it
to the actual type of the function argument".

I've now checked GCC sources, and it seems that this warning is
unconditional in 4.1.1, whereas it has been fixed and put under
-Wconversion in 4.2.0.

Yeah, I mostly use C++.
