Also, the issue above is independent of the implicit conversion, it happens
also for int and INT_MIN. Unfortunately, there is some controversy among GCC
developers about whether this is the desired behavior of the warning or not. A
solution that may be accepted by all is to have a new warning option that does
not warn for cases where the target type is the same as the operand type. But
someone needs to implement this solution.
