They (ntoh64 & hton64) are only used in a few places. In fact, only one
file. So for now they go into the file.

But I'd vote for us adding them. I think they will be useful (isn't IPv6
going to some huge address size?), and we could help set a standard.

I'd actually vote that we move towards numbering, as ntohl & ntohs
implicitly assume that a long is 32 bits and a short is 16. Shouldn't
htonl really convert whatever a "long" is from NBO to HBO, even if a long
is 64 bits?

As a compromise, how about we make both letter and number names, and
recomend people migrate towards the numbers. ??

Take care,
