It was new in GCC 4.7, http://gcc.gnu.org/gcc-4.7/changes.html
I've seen spews of that warning for other large projects, such as clang or wxWidgets, not just boost.
Would GCC consider removing it from -Wall?
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
