 * This file contains definitions of flag translation tables for the
 * open() system call.  Since the tables are nearly identical
 * across target platforms (other than the values of the target flags),
 * we use a single copy of the tables but include it separately for
 * each target platform.  The TARGET macro must be #defined before including
 * to indicate the class for which the table is being defined.
