It is relevant that the invariant sections are not executable code;
since they do not affect the execution of the program, they are only
one step further from an author attribution notice that may not be
removed.
The latter are allowed under GPLv3 as an Additional Term
under 7 b - does that make GPLv3 w/ author attribution similarly
non-free in the eyes of Debian?
