Hi All...

I made a small patch to keychain, so that it creates an additional pid file 
named ~/ssh-agent.bat

This allows non-cygwin ssh-aware programs (such as unison) to take advantage 
of the keychain functionality. The new file can be used from a windows 
command script by

call C:\Cygwin\home\kmoerder\ssh-agent.bat

or better yet

if exist C:\Cygwin\home\kmoerder\ssh-agent.bat call ...

Thanks,

...Karl
