Comment (by johndoe):

Well, I tried to modify `specs` directly, but project failed to build: I've got messagebox that `setup.exe` crashed. That was on my local machine, but the same you can see on appveyor: https://ci.appveyor.com/project/johnd0e/pandoc/build/1.0.79

I am not sure, maybe my `specs` file is not good: https://github.com/johnd0e/pandoc/blob/master/specs But it worked well with other project (not GHC).
