Thanks for for filing the ticket John.
Turns out Cabal is doing it right and it's c2hs that we need to fix.
Shouldn't be too hard. Just need to change the way c2hs invokes cpp in
let cmd = unwords [cpp, cppOpts, newHeaderFile, ">" ++ preprocFile]
exitCode <- liftIO $ system cmd
to something like:
let args = cppOpts ++ [newHeaderFile]
tracePreproc (unwords (cmd : args))
exitCode <- liftIO $ do
preprocHnd <- openFile WriteMode preprocFile
process <- runProcess cpp args
Nothing (Just preprocHnd) Nothing
Try that, tell me if it works and we can add the patch to the c2hs repo.
