Description

clang-3.6 introduces a new warning for unused local typedefs, which is enabled by -Wall and causes a build failure in debug mode (due to -Werror).

Nothing we can do since it's in boost. Therefore I propose to disable the warning (-Wno-unused-local-typedef) or make it non-fatal (-Wno-error=unused-local-typedef).
