Esegui ./python -m test -v test_os su Windows e leggi Lib/test/test_os.py nelle vicinanze di test_attributes, check_entry e assert_stat_equal. Confronta il fallimento con la PR collegata gh-156305; il lavoro è completato quando test_os passa su Windows senza la discrepanza st_file_attributes segnalata.
