Okay, followup question. If a BSD application automatically converts to
the GPL by linking to a GPL library, can the application still be
distributed under the BSD license? Second follow up. Does this mean
that another party can change my license to the GPL against my wishes
by merely linking my code to a GPL library? I thought (and still
believe) that only the copyright holder can change the license.
