Why hide Distribution.Compat.FilePath, or what to use instead?

Hi Dimitry,

you don't want to use Distribution.Compat.FilePath, it is not there  
anymore in future versions of Cabal, starting with 1.1.7. In my  
experience, the only things that you will miss in filepath are those  
exeExtension, dllExtension... functions. It may be reasonable to  
import those from  Compat.FilePath if you want, because they are kept  
(in another module I believe) in Cabal 1.1.7. Or better, update to  
Cabal 1.1.7 and import theM from the right module

To unhide the module, you need to list Cabal as a dependency in the  
Cabal descriptor.
