../src/as-pool.c:1287:29: error: implicit declaration of function ‘g_ptr_array_steal_index_fast’; did you mean ‘g_ptr_array_remove_index_fast’? [-Werror=implicit-function-declaration]

g_ptr_array_add (result, g_ptr_array_steal_index_fast (tmp_res, 0));
                         ^~~~~~~~~~~~~~~~~~~~~~~~~~~~
