    Propagate the value of CYGWIN environment variable into scripts
    
    Propagate the value of the CYGWIN environment variable into the
    sanitized environment we use to run scripts.
    
    Note: as it stands, this isn't always useful as the initial environment
    isn't propagated when setup re-runs itself elevated.
