commit c875b085d95377771a5b3cf0f44bb2910dbfe966
Author: Thomas Miedema <thomasmiedema at gmail.com>
Date:   Sat Jul 4 18:20:06 2015 +0200

    Use -fno-warn-unused-imports instead of hiding `ord`
    
    This is more future proof. Maybe later versions of Alex won't `import
    Data.Char (ord)` anymore.
