It is an issue of my own making. We still have quite a few released libraries
built on boost 1.33. Our newer prototype version is 1.34 based. It is now
generating files that can't be read by those older binaries. In my case, I am
lucky enough that the format is actually compatibly, except for the version
number and a couple previously non-existend lines (if I change the file to 3,
and remove two lines, it all works).

So, my problem is that we need to move to Boost 1.34, but I need a serialization
library that interoperates with 1.33 serialization. I could hack my code to
post-process the file, but it would be ugly.

I phrased that horribly. I meant, has anyone tried to use the Boost 1.33 version
in 1.34 (instead of the one that ships with it).
