Comment (by asr):

 Replying to [comment:3 asr]:
 > If I understand correctly, the proposed fixes require at least `Cabal >=
 1.24`. Is there a fix which also work with the `Cabal` version (i.e.
 `Cabal 1.22.*`) shipped with `GHC 7.10.3`?

 I realise that oldest versions of Cabal just ignore the `custom setup`
 stance, so please ignore my question.
