- * The only exception is if we're on a platform with no 64-bit type at

- * Because we use read_longint() to get these off the wire, if you

- * with no 64-bit types then you will get an overflow error. Probably
- * not many people have that combination of machines, and you can
- * avoid it by not preserving hardlinks or not transferring device
- * nodes. It's not clear that any other behaviour is better.
- *
- * Note that if you transfer devices from a 64-bit-devt machine (say,
- * Solaris) to a 32-bit-devt machine (say, Linux-2.2/x86) then the
- * device numbers will be truncated. But it's a kind of silly thing
- * to do anyhow.

- * where dev_t is a struct.
