G_THREADS_ENABLED still exists, but is always defined. It is still possible to use libglib without threads, but gobject (and everything above it) is now guaranteed to be using threads (as, in fact, it was before, since it was accidentally impossible to compile with --disable-threads). https://bugzilla.gnome.org/show_bug.cgi?id=616754
