 * RULE Rule-2.1 (Required):
 * A project shall not contain unreachable code
 * 
 * Implemented by messages:
 *  594   Negative 'case' label expression is incompatible with
 *        unsigned controlling expression in 'switch' statement.
 * 
 * 1460   'Switch' label value, %s, not contained in enum type.
 * 
 * 1503   The function '%1s' is defined but is not used within
 *        this project.
 * 
 * 2742   This 'if' controlling expression is a constant
 *        expression and its value is 'false'.
 * 
 * 2744   This 'while' or 'for' loop controlling expression is a
 *        constant expression and its value is 'false'. The loop
 *        will not be entered.
 * 
 * 2880   This code is unreachable.
 * 
 * 2882   This 'switch' statement will bypass the initialization
 *        of local variables.
 * 
 * 3219   Static function '%s()' is not used within this
 *        translation unit.
