Or performing a cast? 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. > Also you're compiling a .cc file which GCC assumes is C++ not C. Yeah, I mostly use C++. -- Sergei.
