have you had a look at

my goal is to have an abstraction in the code regarding the on-disk
format. The first goal is to have a common data format on all
platforms plus the ability to update/read the old native format of
the platform. But even cooler would be to make it so that formats
of different platforms would become accessible.

looking at your code, you seem to have some good insights into how
to wrestle something like this into shape.

on another note, have you considered running a 32bit version of
rrdtool on your x86_64 platform ?
