Error code 23, delete failed, error 0

[Rob Bosch]

I'm getting errors in my rsync.logs using rsync3.0.0pre8 with the -vv
option.  The client is running on cygwin as the client, CentOS as the
server.  The error in the log is:

rsync: delete_file: rmdir(filepath) failed: No error (0) 

When I look on the server/receiving side the directory does not exist.  Just
trying to understand why this would cause a non-zero exit code.
