Hmm.  Does the gnu.linkonce trick work for shared libraries?
(If you were building an executable and multiple .o files use,
say, vector<int>, more than one .o file would have a definition
of some of the vector<int> functions but the GNU linker would
eliminate all but one copy.  I don't think this works for shared
libraries, though I may be wrong).
