Comment(by cal@…):

 The clang compatibility problems are instances of
 http://clang.llvm.org/compatibility.html#dep_lookup_bases,
 http://clang.llvm.org/compatibility.html#dep_lookup and
 http://stackoverflow.com/questions/7774188/explicit-specialization-after-
 instantiation. I've attached a set of patches that fix the build with
 clang. If the maintainer approves, I will commit them.

 Since the hard work has already been done, these patches should probably
 be sent back upstream, too.
