    pygtkcompat: Work around IndexError on large flags
    
    On 32 bit systems pygtkcompat currently fails with
    
      File "pygtkcompat/pygtkcompat.py", line 74, in _install_enums
        name = flag.value_names[-1].replace(modname + '_', '')
    IndexError: cannot fit 'int' into an index-sized integer
    
    on 32 bit systems as some flags in Gdk are too large to fit into a 32 bit
    "long". Work around this crash until this gets fixed properly (marked as
    FIXME).
