POSIX file descriptors are not the same as MPE file numbers.  From
/usr/include/fcntl.h:

#define _MPE_FILENO(fd)   (((fd)>2 && (fd)<10) ? (fd)+1014 : (fd))
    /* POSIX file number to MPE file number */
#define _POSIX_FILENO(fn) (((fn)>1013 && (fn)<1024) ? (fn)-1014 : (fn))
    /* MPE file number to POSIX file number */

You need to compile with -D_POSIX_SOURCE or -D_SOCKET_SOURCE to get those defines.
