   A brief question: are htonl(), ntohl() and friends allowed to evaluate   
   their argument more than once (i.e. if they're implemented naively as   
   macros?)   
      
   The man pages I've seen are silent on the subject so one would assume   
   they behave like normal functions -- but I've wasted a day debugging a   
   problem caused by my (in-house) implementation evaluating the argument   
   four times.
