Re: [boost] lots of warning with gcc-4.8.1 + boost-1.54.0

Lots of warnings like this:

./boost/bind/arg.hpp:37:22: warning: typedef ‘T_must_be_placeholder’ locally defined but not used [-Wunused-local-typedefs]

when building 1.54.0 with gcc-4.8.1 (fedora f19)

This warning is new in GCC 4.8, and I have been seeing a ton of them not just in boost, but in every codebase I've built. IMO gcc should not have this warning turned on by default. CC'ing the gcc folks. Regards, Nate
