 void bb_perror_nomsg(void)

 {
-	/* Ignore the gcc warning about a null format string. */
-	bb_perror_msg(NULL);
+	bb_perror_msg(0);
 }

Why don't use NULL here?

It seems gcc 3.3.5 or above is smarter on this.  If I add another
parameter after `NULL', it'll warn:

   warning: too many arguments for format

Otherwise, it just keeps silent.
