Was this behavior of ++ intentional and documented? Was it's use by this
code intentional? Is this code never intended to be compiled by any
compiler that fails to support this behavior? If the answer to all three
question is "Yes", I can't accept "broken" as a term for code that
reliably, in the context it's intended to be used, works precisely as it
was intended to work.
