The idea was to avoid exporting private symbols, and also to avoid
having to build the binary with any dynamic link flags. Since the Glade
3 change, the binary has dynamic link flags anyway, so the reason for
this is gone.
Note: It's a bit annoying that all binary symbols are exported (on some
platforms), ideally only symbols marked with some kind of export
attribute would be.
