121,Fail to link haskeline 0.7.0.x on Windows.,shelarcy,,"System.Console.Haskeline.History module depends on System.Console.Haskeline.Backend.Posix.Recover module even though Windows. 

  http://hackage.haskell.org/packages/archive/haskeline/0.7.0.0/doc/html/src/System-Console-Haskeline-History.html#line-35

But only unix environment specify as the Other-modules to System.Console.Haskeline.Backend.Posix.Recover in .cabal file. Windows environment doesn't specify  as the Other-modules to that in .cabal file.

  http://hackage.haskell.org/packages/archive/haskeline/0.7.0.1/haskeline.cabal

So, GHC fail to link System.Console.Haskeline.Backend.Posix.Recover modules' symbol when building program on Windows.
