commit ccec71ec318fdf739f55858d5bffaf4fd6520036
Author: Sergey Poznyakoff <gray@gnu.org.ua>
Date:   Mon Feb 20 19:51:27 2012 +0200

Always use 32 bit CRC
    
    * src/cpiohdr.h (cpio_file_stat) <c_chksum>: Change type to
    uint32_t.
    * src/extern.h (crc): Change type to uint32_t.
    * src/global.c: Likewise.
    * src/copyout.c (read_for_checksum): Return uint32_t.
    * src/copyin.c: Fix printf formats.
