---------------------------------+------------------------------------------
 In ghc-6.12, we had the situation that base-3 was a wrapper around base-4.
 The modular solver can currently not handle that situation, thereby making
 it mostly useless when used with ghc-6.12. For later ghc versions, this no
 longer occurs, thus isn't an issue. This is one reason why the modular
 solver currently is not the default.

 Options:

    * Add a hack to the modular solver to deal with it, much like it is
 done in the topdown solver.
    * Make the default solver being used dependent on the version of ghc
 (but that might be confusing).
