The build is broken on {32,64}-bit Windows

[Páli Gábor János]

Hello there,

For your information, the build has been failing for a few days now on
both my Windows builders [1][2], basically in the same way.

librarieshaskelineSystemConsoleHaskelineBackendWin32.hsc:263:15:
    No instance for (Applicative (Draw m))
      arising from the 'deriving' clause of a data type declaration
    Possible fix:
      use a standalone 'deriving instance' declaration,
        so you can specify the instance context yourself
    When deriving the instance for (Monad (Draw m))

Could somebody do something with this, or does anybody have hints on
how to fix this?  Looks like the culprit is the haskeline library.
