If the user chooses `yes' and there is no SVG library, this is an
error, and the `configure' script should exit with an error message.
`auto' selects between `yes' and `no', not `no-default'.
`no-default' should be a separate option that must be explicitly
selected.
Thanks for clarifying. I'll make the necessary changes soon. :)
