GCC doesn't emit this warning if such typedefs are annotated with __attribute__((__unused__)). We just need to fix all instances of this problem. So far I identified these there: - https://svn.boost.org/trac/boost/ticket/8844 (Boost.Bind) - https://svn.boost.org/trac/boost/ticket/8847 (Boost.ConceptCheck) - https://svn.boost.org/trac/boost/ticket/8859 (Boost.Serialization) Thanks, PM
