test_create_directory_with_write in test_zipfile fails in AIX with the below message

======================================================================
FAIL: test_create_directory_with_write (test.test_zipfile.test_core.TestWithDirectory.test_create_directory_with_write)

Traceback (most recent call last):
File "/cpython/Lib/test/test_zipfile/test_core.py", line 2879, in test_create_directory_with_write
self.assertEqual(zinfo.external_attr, (mode << 16) | 0x10)
AssertionError: 1106051088 != 5401018384

The reason being AIX stat call st_mode returns 240700 (in octal) for a directory with 700 mode. In linux, it returns 40700. So there is extra “2” which seems to be related to journaled filesystem. So the logic requires that the mode should go a bitwise AND operation with 0xFFFF , like how it is done intest_write_dir intest_core.py to be in sync withzinfo.external_attr
