Is that for real? I admit I have not used this library so maybe I should be
ignored, but what is the reasoning for only being able to serialize consts?
At the moment it does not sound useful.

One tip --> in 1.33 you will need to make the date const or oa << d will
Serialization is now enforcing this previously documented part of the
date d(2004, Apr, 5);
needs to be
const date d(2004, Apr, 5);

It's missing :-(

Doesn't seem like it. I'm getting the same problem on Linux with gcc 3.x
with the modification suggested above. I'll look into it and let you know.
BTW, the regression tests are passing, so I'm unsure what's happened here...
