I now have a nice little thick binding built for NT services that seems
to be working. Its a generic that you simply instantiate with your
handler routines. It takes care of all the details of registering the
service and its handlers with NT.

It appears to work nicely. The only real glitch I've seen is that some
test code of mine, in trying to write to a file in a handler, causes an
exception to get raised (and handled) in the ServiceMain routine, which
should be in a completely different thread!

Other than that, with Gnat Text_IO to files works fine. "delay" works
fine. I haven't tried any other tasking or protected type primitives
yet. I'm having trouble creating processes with CreateProcess, but
that's probably an unrelated bug.

Right now I'm using this as part of a mini-project to create a SETI@Home
controller service (something I've wanted for a while), which I plan to
release as free software if I can get it working well enough. If anyone
is interested in the NT service binding itself, let me know.

Would someone familiar with CLAW care to comment on how/if it handles NT
services? I'm interested in what other thick bindings have done.
