Win32: additional error code NGX_EEXIST_FILE (ticket #910). On Windows there are two possible error codes which correspond to the EEXIST error code: ERROR_FILE_EXISTS used by CreateFile(CREATE_NEW), and ERROR_ALREADY_EXISTS used by CreateDirectory(). MoveFile() seems to use both: ERROR_ALREADY_EXISTS when moving within one filesystem, and ERROR_FILE_EXISTS when copying a file to a different drive.
