mdl_output.cpp: In function ‘void mdl_print_nonstructured_to_chan(mdl_value_t*, const mdl_value_t*, int, bool, bool, mdl_value_t*)’:
mdl_output.cpp:698:38: warning: format ‘%llo’ expects argument of type ‘long long unsigned int’, but argument 3 has type ‘long int’ [-Wformat=]

Should be safe to do an explicit conversion:

                sprintf(buf, "*%022llo*", (long long unsigned) a->v.w);
