I know this very good: in the Cygwin-svc code I have already set a Tcpip &
Afd dependency like Apache service. But, with the latest Cygwin, Squid
service no more starts, and ONLY in NT eventlog I can found time-out
events, so Squid code doesn't start. Please note that the some service code
with Tcpip & Afd dependency runs very fine in the NT 2.3 branch.

I think that cygwin1.dll try to make some new long initialization (or it
wait for the start of some service), but it can't signal anything to
service control manager because it doesn't know to run as a service. This
morning Squid doesn't start at boot again, even with LanmanWorkstation
dependency, with the same time-out errors.

So may be that this cygwin1.dll CAN'T run as a service at boot time
(remember same problems on Cygwin mailing list).

I will try to find for you what system calls hangs.
