[Boost-users] auto_link question

When I build the serialization library I get two copies of the diagnostic 
message.

I asked this before but now I can't find the answer.  It seems that it was
suggested that this was symptom of some sort of mistake that could/should
be corrected.  In studying this I've come upon the following scenario.

library ab contains

a.cpp - with interface in a.hpp
b.cpp - with interface in b.hpp

User programs might contain a.hpp or b.hpp or both
depending on what they want to call.  So each of
a.hpp and b.hpp should contain auto-link to generate
the pragma corresponding to the library ab.  However
if, it the user includes both a.hpp and b.hpp - which
he gets two diagnostic messages - since auto_link.hpp
has no include guard.  If this is a mistake, where is it
and who is making it?
