    gmmproc: _WRAP_ENUM: Skip enum constants whose names are deleted.
    
    * tools/pm/Enum.pm, build_element_list(): If a custom substitution argument
    in _WRAP_ENUM() removes all of an enum constant's name, exclude that constant
    from the element list. Useful for GdkEventType. Bug #544694.
