Yes, and all symbols have a different version name in 1.0.2 and
1.1.0. (What is actually the important thing.)

When linking you actually get a warning.

As far as I know, it should only break when they use dlopen().
They most likely won't be using dlvsym() in that case and then it
can pick any version. It could of course also break if they do
very weird things.

But I guess we'll have to see if something breaks or not.
