Both can be loaded and if we have the luck that only one version of a
symbol gets loaded, it could happen that we take all symbols from
one library but the ones that are unique to the other library
are used from this one.

Both versions are not compatible and we should clearly mark them so.
I think even if it would not happen in practice, I'd like to change the
magic value. As debugging such problems is really, really ugly without
the abort directly when it happens.

This patch compiles...now
