Amplification:
This rule applies to all keywords, including those that implement language extensions.
Example Code:
#include "misra.h"
#include "m3cmex.h"
extern int16_t rule_2004( void )
{
return 1;
}
#define auto AUTO /* 3439 */
#define break BREAK /* 3439 */
#define case CASE /* 3439 */
#define char CHAR /* 3439 */
#define const CONST /* 3439 */
#define continue CONTINUE /* 3439 */
#define default DEFAULT /* 3439 */
#define do DO /* 3439 */
#define double DOUBLE /* 3439 5209 */
#define else ELSE /* 3439 */
#define enum ENUM /* 3439 */
#define extern EXTERN /* 3439 */
#define float FLOAT /* 3439 5209 */
#define for FOR /* 3439 */
#define goto GOTO /* 3439 */
#define if IF /* 3439 */
#define int INT /* 3439 5209 */
#define long LONG /* 3439 5209 */
#define register REGISTER /* 3439 */
#define return RETURN /* 3439 */
#define short SHORT /* 3439 5209 */
#define signed SIGNED /* 3439 5209 */
#define sizeof XSIZEOF /* 3439 */
#define static STATIC /* 3439 */
#define struct STRUCT /* 3439 */
#define switch SWITCH /* 3439 */
#define typedef TYPEDEF /* 3439 */
#define union UNION /* 3439 */
#define unsigned UNSIGNED /* 3439 5209 */
#define void VOID /* 3439 */
#define volatile VOLATILE /* 3439 */
#define while WHILE /* 3439 */
/* additional keywords required for C99 */
#define inline INLINE /* 3439 */
