Can't chmod 700 in Windows 8 CP x64

[lost]

Hi everyone!

I faced this problem while trying to use public key authorization with
ssh (it says, key permissions are too open). I tried chmod 700 id_dsa,
but that resulted in 770 permissions. I can't set zero second digit.
It seems I'm not the only one with this problem:
