 Component:  Cabal library    |      Version:  HEAD

Difficulty:  easy (<4 hours)  |   Ghcversion:  6.8.3    
  Platform:                   |  
------------------------------+---------------------------------------------
 It is possible to build ghc without support for object splitting. In such
 a case Cabal should refuse to work if the user enables split objs.

 All one has to do is to parse the output of `ghc --info` (which is in a
 `Read/Show` format).

 See also #24.
