With the latest Cabal (as included in recent GHC), the postInst.sh
(which is the problem) can be rewritten in Haskell and added to Setup.hs
directly.  That should remove this particular problem (but will of
course mean that c2hs doesn't work anymore with earlier versions of
Cabal, but that is probably secondary).

What else apart from pathname separators?  It'd be great if somebody
could look into that.
