mc2_1909.c contains following code:

Code:
#define SUM(A,B,C) ((A) + (B) + (C)) /* Violates Rule 17.4 */

Rule 17.4 is "Array indexing shall be the only allowed form of pointer arithmetic." - the code does not seem to be violation of this rule.

Code:
#define SUM(A,B,C) ((A) + (B) + (C)) /* Violates Rule 17.4 */

The comment above is incorrect. This is a function-like macro which violates rule 19.7.

Code:
mc2_1909_s16a = SUM( 5,

#ifdef SW

                        mc2_1909_s16b,

#else

                        mc2_1909_s16c,

#endif

                        0 );

The above lines should be flagged as a violation of Rule 19.9.
