 * File:		aixwrap.c
 * Description:
 *     This file contains a single function, _MD_SELECT(), which simply
 *     invokes the select() function.  This file is used in an ugly
 *     hack to override the system select() function on AIX releases
 *     prior to 4.2.  (On AIX 4.2, we use a different mechanism to
 *     override select().)
