Thanks for the report. I see where the problem occurs. It's one of
the hoops the rename(2) function jumps through to support .lnk-style
symlinks which has a buggy condition. This should be fixed in CVS.
If you're not set up to build your own Cygwin, please give the next
developer snapshot a try.
Thanks,
Corinna
