I don't think it's really the point. There actually has to be only one thread
besides the process' main thread, the one that is produced by the call to
StartServiceCtrlDispatcher (Service_Table);
It's true that it's convenient to make a service multithreaded, at least to be
able easily pause and resume it, but there's no such a requirement at all.

I just don't see how one using cygwin32 gcc can build an application that uses
Win32 SDK API. Say you need to use winsvc.h #include file for the data structures
like SERVICE_TABLE_ENTRY to be defined and there it starts -- gcc gives a lot
of stuff like "in the file included from service.c: winsvc.h: ..."

The solution is maybe to compile separately the code for the service itself by gcc
and all the stuff you need to `decorate' the application as an NT service by MS VC++
and then link it together (I don't know whether it's possible or not)
