I put a fopen, fputs and fflush at the top of service_main before anything 
else happens. The times when cygrunsrv starts up, everything works and I get 
my output. The times when it does not start, I get nothing (no file creater 
and no output).

I also completely removed cygwin and reinstalled everything with setup 2.57. 
No change: sometimes it works, sometimes it doesn't. I wasn't expecting this 
to make a difference.
