soemthing like

Can't find room 'inthere'.
Can't find room 'inthere'.

to fix,  room.c : trans_fn ()

add the declaration
   room    *r;


then change
   move_to(p, str, 0);
   do_str_inform(p, str);
to
   r = p->location;
   move_to(p, str, 0);
   if (r != p->location)
      do_str_inform(p, str);
