commit 7a48e6caad54609f1bbefc3bd60e8352edcd2cc7
Author: Herbert Valerio Riedel <hvr at gnu.org>

    Make ghc-cabal's `System.Directory` import more robust
    
    Starting with directory-1.2.5 there will be a nameclash with
    `withCurrentDirectory` and `MIN_VERSION_filepath()` isn't available at
    bootstrap-time with the current GHC build-system.
    
    By using explicit import lists we avoid CPP altogether
