Description (last modified by mietek)
Haddock fails to cooperate with OS X clang CPP:
<no location info>: module ‘pkgid-pkgversion:Main’ is defined in multiple files: dist/build/tmp-#####/Stuff
A workaround is to pass --ghc-options=-optP-P to cabal haddock.
This prevents cabal-install from bootstrapping, unless --no-doc is specified.
The original Haddock ticket and the corresponding Cabal issue were both closed as invalid, but there appears to be no GHC ticket to track the underlying cause.
