These give source compatability. I need binary compatability. Let me
expand; I am working on a new High Availability, large scale file server.
The entire server stores all numeric data as 64bit quantities (the decision
to do so is a bit outside the scope of this note :-). Part of the HAS
concept is integral support for clustering. I.E. Multiple nodes/hosts can
concurrently access the same physical filesystem. To ensure portability, I
need to store these values in a universal format.

See my comment above. You can view my need as a network need :-)

Thanx! Gone are the VAX orders, then...
