 - Issue #20517: Added new functions allowing OSError exceptions to reference
-  two filenames instead of one: PyErr_SetFromErrnoWithFilenameObjects(),
-  PyErr_SetFromErrnoWithFilenames(), PyErr_SetFromWindowsErrWithFilenames(),
-  PyErr_SetExcFromWindowsErrWithFilenameObjects(), and

+  two filenames instead of one: PyErr_SetFromErrnoWithFilenameObjects() and
