There appears to be a regression in the most recent OpenSSH cygwin
package (5.9p1-1, built 1/18/2012) related to the ssh-agent program.

The ssh-add program is unable to add SSH keys because the ssh-agent
program doesn't appear to be creating its socket file properly in
/tmp.

Platform: Windows 7 64-bit
Steps to reproduce:
1. Install OpenSSH 5.9p1-1 in Cygwin (or upgrade to it)
2. Run the ssh-agent program spawning a bash shell
  $ ssh-agent bash
3. Run the ssh-add program with no arguments:
  $ ssh-add
4. You will receive the following error message
   Could not open a connection to your authentication agent.
5. You should be able to confirm that the SSH_AUTH_SOCK environment
variable points to a file that doesn't exist in /tmp
   $ env | grep ^SSH
   SSH_AGENT_PID=8564
   SSH_AUTH_SOCK=/tmp/ssh-ipSOmcSz8532/agent.8532
   $ ls -l /tmp/ssh*
   ls: cannot access /tmp/ssh*: No such file or directory

Workarounds: Downgrade to OpenSSH_5.8p1 using Cygwin's setup.exe.
