It is, actually, and i'm confused what Josef thinks is wrong.

Josef, it does generate *markers* for the struct definition, they just 
are never *used* anywhere.

It uses the right markers for the table:

static void gt_ggc_ma_decl_loc_table PARAMS ((void *));
static void
gt_ggc_ma_decl_loc_table (x_p)
       void *x_p ATTRIBUTE_UNUSED;
{
   if (decl_loc_table != NULL) {
     size_t i0;
     ggc_mark (decl_loc_table);
     for (i0 = 0; i0 < (size_t)(decl_loc_table_allocated); i0++) {
       gt_ggc_m_12var_loc_node (decl_loc_table[i0].first);
       gt_ggc_m_12var_loc_node (decl_loc_table[i0].last);
     }
   }
}
