    top(1): Silence gcc warnings.
    
    The ORDERKEY_XXX() macros build up a deeply nested set of if-statements.
    E.g.,
    
    if (expr)
       if (expr)
          if (expr)
          	 if (expr)
    
    The last if-statement needs to contain nothing (every expression has
    its own side effect, so the whole cascade is actually meaningful). Using
    a ; though, makes gcc generate warnings regarding 'empty body in if
    statements'. That's why we, instead, use:
    
    ORDERKEY_FOO1
    ORDERKEY_FOO2
    ...
    ORDERKEY_FOO3
    {}
    
    We could have embedded the {} in the definition of the macro itself, but
    that would break if someone rearranged the macros' call order.
