I think at least for Linux and Unices this gets solved when linking the final executable. Stuff in an archive (static library for you AIX users) that is not referenced evaporates.

It's also need for fast linking. You just create a link line that creates an executable based on one or more objects files in front of an archive. The symbols in the object file take precedence, which can make incremental builds really fast. This last bit is where cmake is much slower than my original build system, but arguably more safe.
