'With a better linker' is not really an answer, or at least not one that
would really help you. You can somewhat work around by not linkning
libraries directly into each other or executables but dlopen-ing them.
Ultimately - gnome the platform provides a certain (not so small) set of
fetaures which are presently divided between libraries in a reasonable
way. That's not probablt the right angle to attack it.
