What is the problem with the cast? Do you want a warning for the conversion that you asked for with the cast? We want about implicit conversions with -Wconversion but if you use a cast, we understand that you really mean to perform the conversion. Notice that without -pedantic you don't need to do anything, the value is kept as it is. With -pedantic, you don't need the cast either, it is automatically converted to an int (yes, there is a conversion but that is what the warning is telling you). If you use a cast, then you perform the conversion yourself and there is nothing to warn about. Cheers, Manuel.
