I have now added a primitive, called w32-window-exists-p, that you can
use to check whether the agent is running on Windows.  To that end,
test whether w32-window-exists-p is fboundp, and if it is, see if the
expression `(w32-window-exists-p "Pageant" "Pageant")' evaluates to a
non-nil value.  If it does, the agent is running.

I hope this resolves the issue in a way that the Windows port can now
work the same as the Unix one.
