Yes.  It's an uncompressed disk image of a 26-Gbyte disk.

# 104 "c:/chris/mingw/2.0.0-3/include/sys/stat.h" 3
struct stat
{
        _dev_t st_dev;
        _ino_t st_ino;
        _mode_t st_mode;
        short st_nlink;
        short st_uid;
        short st_gid;
        _dev_t st_rdev;
        _off_t st_size;
        time_t st_atime;

        time_t st_mtime;
        time_t st_ctime;
};

# 53 "c:/chris/mingw/2.0.0-3/include/sys/types.h" 3
typedef long _off_t;

This program:

  main() {  printf("%d", sizeof(long)); }

prints "4"

Sounds like you've found the cause of the problem.

Chris.
