Hi, At some point in the history of the c2hs repo, the files hipar/base/todo and hipar/base/TODO both exist. This is not good for people who want to get the repo on Windows :-) After playing around a bit, I have made a version of the repo that can be got fine from Windows. It doesn't involve modifying any existing patches, just adding a couple of new ones and reordering them in the repo so that the two files todo and TODO never exist simultaneously. My fixed up repo is at http://urchin.earth.li/darcs/ganesh/c2hs - I believe that you can sort out the main c2hs repo by getting a fresh copy from my repo, pulling in all the outstanding changes from the original c2hs repo, and then swapping the new one into place. A more detailed explanation: The current repo starts off with hipar/base/todo. At some point later, hipar/base/TODO is introduced. Later still, in the patch "rearranging darcs repo", hipar/base is renamed to base and the new base/todo is deleted. I wrote a patch that renames hipar/base/todo to hipar/base/todo-lowercase. This solves the name conflict for Windows, but annoyingly it conflicts with the delete of base/todo later on, so another patch is needed to resolve this conflict. There's also a final patch at the end to actually delete the renamed todo-lowercase file, because I got confused when resolving the conflict and didn't do it then, and I only realised after the person I was helping on #darcs had pulled from me. So the sequence of patches in the modified repo is: - Original import - Rename hipar/base/todo to hipar/base/todo-lowercase - "rearranging darcs repo" and all its dependencies - Resolve conflict between rename of todo and delete of todo - Rest of the patches - Actually delete base/todo-lowercase Cheers, Ganesh
