I saw recently that gcc 4.0 will be able to help with this. Apparently
the webpage is gone now (it was at
http://www.nedprod.com/programs/gccvisibility.html), but the essence
is that gcc 4.0 can make symbols not visible unless you explicity
tells it that they are.

GTK+ and GLib currently has a scheme to do this with invisible
'internal aliases', but doing it with gcc should be a bit easier.
