Haddock itself never defined __HADDOCK__, because it didn't do the CPP
preprocessing itself. Cabal adds __HADDOCK__ itself when preprocessing
files for passing to Haddock. When used with Haddock version 2, Cabal no
longer defines __HADDOCK__ when preprocessing.
Haddock 2 can do the preprocessing itself, because it is processing the
Haskell files using the GHC API. In this case, if you want __HADDOCK__
defined, you have to add it explicitly with --optghc -D__HADDOCK__.
The easiest way to use Haddock 2 is via Cabal, which will automatically add
the appropriate options for your package, including the right -B option
which Haddock now needs in order that the GHC API can find its package
