This works fine in coreutils-8.15. Actually, this was an intentional upstream change made by coreutils 8.16, but which has a negative effect on cygwin .exe magic. The real reason for the change is this upstream testcase: $ ln -s nowhere a $ ln a b $ mv a b $ ls [ab] b In coreutils 8.15, this mistakenly errored out instead of deleting 'a'. But the upstream fix for this needs additional cygwin magic to realize that when 'b' and 'b.exe' are both symlinks and have the same inode, then it is the same as a case change, and NOT a case of hard link renames. I'm cooking up the patch now. -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
