No, it was written by an electrical engineering Ph.D. student (i.e. me).

Note that if you are that concerned with warnings (and code quality I
hope), perhaps the best thing to do is start using *stable* versions. If
you use a stable version (1.0.2, but I'll release 1.0.3 soon), you'll
see these warnings go away. Versions 1.1.x are unstable and CVS head is
definitely unstable.
