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

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

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