Thank you for your help.
I tried to copy/paste these files into my project and to modify them in 
order to compile with different primitive types. But new linker errors 
arise because more source files are required. Besides, copying Boost 
files in local project source files is dangerous because the copied 
files have to be updated along with new Boost versions...

So I give up, but I would strongly recommend to allow native template 
archivers with generic primitive types in the Boost serialization library.

Thanks again,
Florent
