Commenting out the -optP-P in Haddock's PreProcess.hs fixes the problem.
Thanks.
Any takers for Duncan's suggested fix?

Fiddling with flags, I see that -optP-P is the culprit. Removing it:
bash-3.2$ ghc -E -cpp -o z src/Graphics/UI/TV/Input.hs -Dmingw32_BUILD_OS -Dmingw32_HOST_OS -Di386_BUILD_ARCH -Di386_HOST_ARCH -D__GLASGOW_HASKELL__=606 -D__HADDOCK__; head -3 z # 1 "src/Graphics/UI/TV/Input.hs" # 1 "<built-in>" # 1 "<command line>" bash-3.2$
Any ideas? - Conal
So for a quick hack, modify Cabal to unconditionally omit -optP-P and see if that makes all your links come out right.
Probably the right thing to do however is to have Cabal use the -optP-P option only when we're using haddock-0.7 or older (otherwise haddock-0.7 users will get a lexical error when haddock encounters the C line pragmas).
I think at the moment Cabal doesn't check haddock's version number at all. So that's something to look at if you or anyone else want to come up with a patch for this.
