You've done a good job chasing down the problem so far, and I
sympathize with the hassle involved in tests that require restarting
NT over and over.

I would suggest adding some trace statements that write to a file
rather than depending on the syslog facility.  I would put one right
after the entry to main() to see if the process is even entered.  Be
sure to flush() the trace output after each message in case the
process aborts and loses buffered output.  I would put another trace
message at the point where StartServiceCtrlDispatcherA() fails in
main().  Then I'd put another right after the entry to service_main().

It looks like failure of StartServiceCtrlDispatcherA() would not be
reported currently, given that error() writes to stderr and that
stream is useless in this case.  However, it's hard to see how that
API could fail in some cases and not others.

Your questions about possible problems in loading the cygwin1.dll
occurred to me too, but I don't know anywhere near enough about Cygwin
to suggest how to explore that possibility.
