I use:

/**
  * Start the RTEMS Shell.
  */
void
shell_start ()
{
   rtems_status_code sc;
   printf ("Starting shell....\n\n");
   sc = rtems_shell_init ("fstst", 60 * 1024, 150, "/dev/console", 0, 1, NULL);
   if (sc != RTEMS_SUCCESSFUL)
     printf ("error: starting shell: %s (%d)\n", rtems_status_text (sc), sc);
}

I suspect something has changed and the documentation is not up to date.

Not sure. I attach the file I use with this code in main:

#if pc586
   int arg;
   for (arg = 1; arg < argc; arg++)
     if (strcmp (argv[arg], "--gdb") == 0)
       pc386_gdb_init ();
#endif

This from the file system test code you can find here:
