Description
The Cabal --c2hs-option option has been ineffective for a long time (haskell/cabal#853), because c2hs does not accept options passed after filenames on the command line:
$ cabal repl --c2hs-option=-h
...
There must be exactly one binding file (suffix .chs),
and optionally one or more header files (suffix .h).
Try the option `--help' on its own for more information.
This is how Cabal attempts to invoke c2hs:
