     Compiler warning (level 1) C4621
 
     no postfix form of 'operator --' found for type 'type', using
     prefix form
 
     There was no postfix decrement operator defined for the given
     type. The compiler used the overloaded prefix operator.
 
     This warning can be avoided by defining a postfix -- operator.
     This is done by creating a two-argument version of the -- operator
     as shown below:
 
          class prepost
          {
          public:
             prepost operator-- ()
             {
                // inline prefix routine
             };
 
             prepost operator-- ( int )
             {
                // inline postfix routine
             };
          }
                                    -♦-
