Redundancy REFERENCE - ISO:C90-6.6.1 Labeled Statements

A label that is not used is harmless except that, like any other redundancy in code, it may cause confusion and is best avoided.

For example: 


/*PRQA S 2006,2015,2017,2201,3227,3408 ++*/

extern int foo(int i, int j)
{
   int r = 0;

   if (i && j)
   {
      r = 1;
   }

A: return r;                    /* Message 3202 */
}
