If the question were about translating the GPLed code into a different
language, in a way that required significant or creative effort, this
would be a good analogy.  The question isn't about that.

A more accurate analogy for the original poster's case would be that
he wants to include short stories by the first author in a collection,
but also include new short stories that use the same characters or
themes as the first author.  As long as the original short stories are
found in the compilation, the original author holds copyright on those
