Comment:

 Regarding the change in memory_datasrc_link.cc, I see why it would work,
 but I do wonder if there is also not some static check that flags using
 methods or constructors that don't put the result somewhere :) (of course,
 if so, it's easy to fix as well)

 The problem in the scoped_lock one really does seem like a checker bug btw

 Changes look OK, but I must admit I have not tried building it with clang
 myself yet.

 In effect, the changes to configure.ac are small, but shall we run it
 through buildbot first just in case?
