+ * that has 64-bit inums.
+ *
+ * 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.
+ *
+ * FIXME: In future, we should probable split the device number into
+ * major/minor, and transfer the two parts as 32-bit ints. That gives
+ * you somewhat more of a chance that they'll come from a big machine
+ * to a little one in a useful way.
+ *
+ * FIXME: Really we need an unsigned type, and we perhaps ought to
+ * cope with platforms on which this is an unsigned int or even a
