From 15eae3dbb3d6824a0fd478e2ce0fe879496bb72c Mon Sep 17 00:00:00 2001

Subject: [PATCH] be coherent in type usage

- no need to use off_t because it is read from strtoul()
- print unsigned int type correctly

When built with _FILE_OFFSET_BITS=64, off_t becomes an long long int
and was printed as an unsigned int which lead to a garbled output.
