void test1(void){

  printf("\ntest1   count = %d ", ++count);

}



void test2(void){

  static int count;                   /* This hides the global count */

}





int main(void){

  int count = 0;                      /* This hides the global count */



  for( ; count < 5; count++) {

    test1();
