You are right -  I just created a test-project with two object files that
stem from .cc-files where the same class with an inlined  function "bar" is
included. What happens is that nm shows me that the function "bar" is
defined weak - according to nm (and what I understand about that) this
means that in presence of another symbol of that name, it will be ignored.
So both files contain a definition for bar, but the linker is able to sort
it out.
