State-Changed-Why:
    Confirmed with present 3.4. The standard says in 3.6.1.2:
    
    An implementation shall not predefine the main function.   This  func-
      tion  shall  not  be  overloaded.  It shall have a return type of type
      int,...
    I can't say whether this rules out having a typedef to
    int instead. I think the answer is: don't do it, there's
    no good reason for such bogosity.
