In dir.c -->

  if (dir->dirstream == 0)
  {
#ifdef WINDOWS32
    /*
     * Check to see if directory has changed since last read. FAT
     * filesystems force a rehash always as mtime does not change
     * on directories (ugh!).
     */
     if (dir->path_key)
     {
       if ((dir->fs_flags & FS_FAT) != 0)
       {
         dir->mtime = time ((time_t *) 0);
         rehash = 1;
       }
       else if (stat(dir->path_key, &st) == 0 && st.st_mtime > dir->mtime)
       {
         /* reset date stamp to show most recent re-process.  */
         dir->mtime = st.st_mtime;
         rehash = 1;
       }
       /* If it has been already read in, all done.  */
       if (!rehash)
         return 0;
       /* make sure directory can still be opened; if not return.  */
       dir->dirstream = opendir(dir->path_key);
       if (!dir->dirstream)
         return 0;
     }
     else
#endif
    /* The directory has been all read in.  */
