lint and the compiler

Nearly five hundred diagnostic messages are issued by lint. However, this list only contains those lint-specific warnings that are not issued by the compiler. Also listed are diagnostics issued both by lint and the compiler that are capable of being suppressed only by lint options. For the text and examples of all messages issued exclusively by lint or subject exclusively to its options, refer to the ``lint-specific messages''. For the messages also issued by the compiler, consult the ``Compiler diagnostics''.
