  19. That means that given
  20.  
  21.   enum c { red, green, blue };
  22.   int f( x ) enum c x; { }
  23.  
  24. there is no strictly-conforming way to write a parameter-list prototype
  25. for the function f.
  26.  
  27.   int f( int );
  28.  
  29. would be right if  enum c  were of short or char size.  If  enum c  were
  30. of int or long size, then
  31.  
  32.   int f( enum c );
  33.  
  34. would be the prototype, right?
