This is an interesting list to look through, but things are not as bad as they look. Many of these are warned about on modern compilers, if you use '-Wextra -Wall'. Some of them are even on by default. I think compilers should warn more eagerly. I would put -Wextra -Wall on by default -- it is easier to turn off things you don't want, than to discover things you do not know exist. But I know this is not a popular opinion!
