... and in this case it would not even have worked: The problem here
was that the user had just the configuration files in two places (not
two complete Sane installations). The "real" configuratio files were
in /usr/etc, which is usually not a place that's used for config
files. What about putting a warning into configure when the config
files go into such a strange place (that is not in /etc or /usr/local/etc)?
