Removing the deprecated stuff is in most cases not an option. But lowering the
impact is. WHat kind of impact have they?

1) longer symbol resolving on startup
2) memory usage
3) locatisation
4) ???

2) can be addressed like i described in
http://bugzilla.gnome.org/show_bug.cgi?id=471123

Now it would be great if we could also tell the linker to resolve deprecated
entries lazily. That would help with 1).

For 3) one could maybe redef _(). Needs to be tried.
