Do you read the announcements? Since 5.7, openssh supports ECDSA keys
per RFC5656. Those are stored in the key file using the above name.

sshd tries to load this key by default, but it's missing in your setup,
that's why you get a warning from sshd.
Re-run the latest ssh-host-config script from the openssh-5.8p1
package. You'll see a line like
*** Info: Generating /etc/ssh_host_ecdsa_key
Afterwards, just answer "no" to all questions. Alternatively, you can
create the key manually:
ssh-keygen -t ecdsa -f /etc/ssh_host_ecdsa_key -N ''
In both cases, make sure the files belong to the user running the sshd
service:
chown cygserver /etc/ssh_host_ecdsa_key*
