   4 Subject: [PATCH] Be coherent in type usage
   5
   6 - no need to use off_t because it is read from strtoul()
   7 - print unsigned int type correctly
   8
   9 When built with _FILE_OFFSET_BITS=64, off_t becomes an long long int
  10 and was printed as an unsigned int which lead to a garbled output.
