Private key file permissions w/Cygwin OpenSSH on Vista

[Siva]

Re:  binary distro of OpenSSH 3.8.1p1

I've been unable to use Cygwin's OpenSSH on Vista w/public key 
authentication because ssh.exe always states the file permissions on the 
private key file--"id_rsa"--are too open.

I've used the chmod.exe utility to change the permissions on the id_rsa 
file to 600, but ssh.exe still pops up with the same error message.

I've also used Windows' cacls.exe command to alter the ACLs for the file 
to be ONLY read-accesible to the current user, and the same thing happens.

This behavior DOES NOT occur on XP and 2000 when I try it, i. e. 
chmod.exe WORKS on these OSs to change id_rsa's permissions so that 
ssh.exe is happy (i. e. to 0600).

Is there a specific bona-fide way to set the id_rsa file's permission to 
always be acceptable to Cygwin SSH on Vista, in addition to the other 
Windows OSs?

Let me know.  Thanks.
