I don't think the loss of precision is an issue here.
It isn't a problem on my little-endian machine (which also has 64-bit IV and 
32-bit mp_prec_t).
I'm thinking that if, on a big-endian machine, I can re-rarrange the byte 
order of the long long (IV) appropriately, then the 'P' specifier should 
still be able to come up with the right figure.
And I speculate that the 'return unpack("J>", pack("J<", $_[0]));' will 
perform that re-arrangement correctly.

At least, that's what I guess/think/hope .... but I don't have a big-endian 
machine at my disposal, so I'm making quite a few assumptions - which is not 
exactly a wise thing to be doing. (I could be way off track :-)

Cheers,
Rob
