Looks a lot nicer. I'll apply it and see how things go. One thing we
need to address:


It's important that we only use this with haddock-1.x. Lots of packages
use this conditional to hide things from haddock 1. However for haddock
2.x the package actually has to be syntactically correct which
haddock-1.x did not require. So using -D__HADDOCK__ with 2.x can make it
not work. We should check if haddock-2.x defines any cpp macros when it
does it's own cpp'ing and follow that.
