Well Corinna.... THANK YOU, THANK YOU, THANK YOU!!!

I finaly has a viable remote admin solution for win9x boxes.  Needless to
say I am very happy about this.

Included is the new source for daemon.c which makes SSHD register itslef as
a service in Win9x boxes.

Its should be noted that only the master SSHD process is set at a service so
if you hapen to be loged on while the user quits his session you will be
bumped off.  The point is that NOW you can get back on the system and
manualy kill the zomby BASH proccess that was left behind.  No more fear of
being locked out of the system.

I would like to say a thanks to:

Max Bowsher
James Coleman
Corinna Vinschen

I could not have done it without you... "Merci beaucoup" as they say here in
Paris.

Ok here is the code:
