[Haskell-cafe] Haddock/Cabal/base bug?

Hi, I want to generate documentation for the base libraries, so I darcs get the base libraries, and a very basic (the sample default) Setup.hs, and try: runhaskell Setup configure runhaskell Setup build Pretty much no luck, but I'll leave that for someone else to sort out :) runhaskell Setup haddock First task is to remove errors about -fno-implicit-bangs, which are in a few files, relatively easy to do. After that it gets quite far (invokes haddock a fair bit) before failing with: haddock.exe: Main.all_subs_of_qname: unexpected unqual'd name:IOMode This is on Windows, cabal, base and haddock all fresh from darcs, GHC 6.4.2 Can anyone point out what the problem is, whose fault it is, and what can be done to fix it? Thanks Neil
