15.3.3 Multiple dependencies
----------------------------

On most modern platforms the order where dependent libraries are listed
has no effect on object generation.  In theory, there are platforms that
require libraries that provide missing symbols to other libraries to be
listed after those libraries whose symbols they provide.

   Particularly, if a pair of static archives each resolve some of the
other's symbols, it might be necessary to list one of those archives
both before and after the other one.  Libtool does not currently cope
with this situation well, since duplicate libraries are removed from the
link line by default.  Libtool provides the command line option
‘--preserve-dup-deps’ to preserve all duplicate dependencies in cases
where it is necessary.
