Note the cygrunsrv error message above. I was able to reproduce it in
non-verbose mode.
Running cygcheck under strace shows that after listing all the available
services, it invokes "cygrunsrv --query grunsrv.exe --list", which results
in the above message. I think this may be because the output of
"cygrunsrv --list" doesn't contain a trailing '\n', and so strtok gets
confused. The following patch (against a slightly older cygcheck) fixes
it for me, but I haven't had the time to test it extensively:
