I hope not: auto-linking doesn't introduce any header dependencies of it's 
own.

I'm paraphrasing but I believe there are two issues here:

1) Some serialisation headers have to be included in a certain order, that's 
a bad thing IMO, and yanking out auto-linking support won't address that.
2) The headers that include the auto-linking code, can be included by 
clients that don't actually need to link to the library. There's no clear 
cut serialisation header that's only included when you need to link to the 
extern lib.

I believe that both issues should be solvable with header refactoring: as 
far as auto-linking goes, it means that the declarations for objects that 
are placed in the compiled lib need to be factored out into separate 
headers.

Robert: is there any help you need from me with the auto-linking code? 
Anything that you don't understand or is causing problems here?

HTH, John.
