The above is true, but then I ran it with --optghc=-D__HADDOCK__ and that
fixed the problem. You see, I didn't know who was actually defining the
__HADDOCK__ macro. Now, after looking at code for Haddock and Cabal, I
realize it's Cabal.

Does Cabal 1.6.0.1 actually define this macro? I don't see it listed when I
run cabal-install with --verbose=3, but I don't know if it's supposed to be
printed.
