So basically if the code continues compiling, even if it produces an
incorrect result, the C++ standard says that the compiler is conformant
because it issued a warning to the end-user instead of an error. Thanks
for notifying me about this. I really did not know that this is how the
standard is written. Needless to say if I were on the C++ standard
committee I would have voted against this, but that is irrelevant to the
way things are. At least I have learned something.
