What happens if two different dynamic objects, destined to be linked
into the same runtime, are linked against different versions of the
library?

E.g. xfoo links libfoo and libbar, two graphics related libraries.
They both have the capability to use DGA, so they both statically link 
the dga lib.

Is that a problem?
