I expirienced the very same problem which you described. I tried to
compile my sources with various options with no success. 

I divided upgrade procedure into two, separate but similar steps.

First, I fetched src/... version just after symbol versioning has been
imported, and it went fine. Once I had my world working, I did second
step by fetching the newest sources at that time and compiled them.

Warnings you've shown here didn't appear then.
