commit fb1fe932038e5a9833fcc5fc53365a2212d76584 Author: Corinna Vinschen <[email protected]> Date: Thu Dec 2 14:13:43 2021 +0100 Cygwin: errno: handle ERROR_CASE_DIFFERING_NAMES_IN_DIR Rather than special case status code 0xc00004b3, add status and matching error code to ntdll.h and handle it as part of the standard error mapping.
