Hi
I'm happy to do the work for adding it to GHC, but I'll need to talk to SimonM when he returns about the details first: It would make sense to either do the switch to building with cabal in 6.8 first (thus avoiding needing to add it the Makefile way), or to do it the Makefile way and also put it into 6.6.1 (which obviously has the advantage that it's available RSN by default with GHC; I don't think there's an interface issue here as it's a separate package, but I'd like to get Simon's input first!).
This hasn't come up before, but I don't see any reason why we shouldn't add to the set of core-packages we ship in a minor patchlevel release.
http://darcs.haskell.org/packages/filepath/ Once you've checked it meets whatever you need, I'll add a darcs tag. If anyone has any comments, please speak up quickly. I'm now NOT looking for remarks like "how about filepath's based on bytestrings?", but if anyone was to take a quick look over the structure, the use of CPP, anything else etc, I'd be grateful. Thanks Neil
