[snmp] AsnUnsInteger64

[Josh Bers]

Yes, for unsigned 32 , however, I am talking about unsigned 64 bit integers,
hence the title of my email. This is for HC counters in the ifXTable for
example... you can probably fake it with long's however, it would be better
to use BigInteger or the like...

Isn't Unsigned Int 32 bits?   If so its below the threshold that would cause
negative values on the long as you have 63 bits before the sign bit on the
signed long.

I do not understand how you can use a long (64 byte SIGNED value) to
represent the unsigned values.. it will have the wrong sign for half the
range of the values. it's not clear that you can create an AsnUnsInteger
correctly for the (negative) values.
