src/Language/C/Analysis/Debug.hs:94:34:
    Ambiguous occurrence `empty'
    It could refer to either `Data.Generics.empty',
                             imported from Data.Generics at src/Language/C/Analysis/Debug.hs:28:1-20
                          or `Text.PrettyPrint.HughesPJ.empty',
                             imported from Text.PrettyPrint.HughesPJ at src/Language/C/Analysis/Debug.hs:29:1-32
