We need the ability to use deep paths for complex builds on Windows 2K. All other calls seem to behave properly if we modify fixpath to avoid using a bad getcwd. Maybe we should only use _truename if we return root as the path. I also did not try using the findfirst call in this patch, but also seemed to perform the same action as truename on "." if it would be a better choice?
