  67 * Strictly speaking, this will lead to invalid C when

  71 *      static const char s[] = ("FOO");
  72 * and in valid C, the initializer on the right hand side must
  73 * be without the parentheses.  But many compilers do accept it
  74 * as a language extension and it will allow us to catch mistakes
  75 * like:
  76 *      static const char *msgs[] = {

  80 *              NULL
  81 *      };
  82 * (notice the missing comma on one of the lines) by forcing
  83 * a compilation error, because parenthesised ("one") ("two")
  84 * will not get silently turned into ("onetwo").
