needing to know install paths

Hi Cabal hackers, For c2hs we've run into a problem. See the thread about c2hs on window over on the haskell list. c2hs wants to install a data file (actually a .hs source file) and wants to know where it's been installed so that c2hs --copy-library can find and copy said file. So how do we do this? At the moment c2hs's Setup.hs calls a postInst script which installs a wrapper script (much like all the little ghc wrapper scripts which specifies the path where things can be found). Of course this doesn't work on Windows. I recall some talk about making this sort of thing easier? Where did we get with that? Duncan
