I can sympathize here.  But the serialization library is already split into 
two libraries.  Combining this with auto-linking turns out to complicate 
things.  Making into four libraries would be even worse.

All I can say it that this has worked from me as well as the testers in our 
matrix.

I do have a good fix for you though.  You can comment out the xml_*.cpp 
files in the Jamfile that builds the library.  This will exclude these 
modules from the library.  This should permit one to build and use all the 
other types of archives.

There is another option as well, for some applications (e.g. those that want 
to do global optimization) it might be more convenient to skip the library 
step altogether and just included the *.cpp files for the archives that are 
to be used.  This seems less attractive to me - but it might be an option 
for some people.
