'cygcheck -srv' is always a help.  I'd suggest *attaching* an uncompressed
version in any follow-up.  How large could it be?  Mine's 43K.

Also, please note that if any of your mounted drives ('/cygdrive/X')
require windows authentication to access, you'll have trouble with that
when running as a service (if the service is run as 'SYSTEM' rather than
under your Windows login).
