Was away for a couple days and just came back to this. Reboots didn't seem to get the DLL replaced, which probably means something is weirdly broken with file permissions in windows on my system. That bodes ill for the future, and probably means a Windows reinstall is in my future.
Eventually I booted to knoppix, deleted the offending file, booted to windows and reinstalled the cygwin package. That fixed the problem.
