gtk_alignment_new was the key:

    /* create/pack statusbar at end within gtk_alignment */
    guint ptop;
    guint pbot;
    guint pleft;
    guint pright;

    GtkWidget *sbalign = gtk_alignment_new (0, .5, 1, 1);
    gtk_alignment_get_padding (GTK_ALIGNMENT (sbalign), &ptop, &pbot, &pleft, 
&pright);
    gtk_alignment_set_padding (GTK_ALIGNMENT (sbalign), ptop, pbot, pleft + 10, 
pright);

    app->statusbar = gtk_statusbar_new ();
    status_set_default (app);

    gtk_container_add (GTK_CONTAINER (sbalign), app->statusbar);
    gtk_box_pack_end (GTK_BOX (vbox), sbalign, FALSE, FALSE, 0);


Now all things are nice and aligned at the same 10 pixel border.
