It's like an "#include <...>" statement in C source code. Compiling it might make a derived work, but it's not a derived work just because it mentions the name of a file it's asking a compiler to include when executed. Anyway, you could possibly argue either way if the .elc file is make a derived work by "linking" to emacs. But the .el file by itself is unquestionably not a derived work and could be under any license at all. -- Wesley J.
