Hi,

For those of you which doesn't follow the discussion on Boost developers mailing list. We now have a new module, Boost.Core. It's a module for various light-weight tools with nearly no dependencies. Headers from Utility, Detail, etc. are being moved into it.

Today the new tool was added - boost::ignore_unused(). More or less it's upgraded boost::ignore_unused_variable_warning(). It allows handling more unused variables than one and unused typedefs as well. Like this:

#include <boost/core/ignore_unused.hpp>

// ...

boost::ignore_unused(v1, v2, v3);
boost::ignore_unused<T1, T2, T3>();

I'd like to use it to fix GCC >=4.8 unused local typedefs warnings (in strategies concept checks). This means that in order to properly build tests you'd need to update ModularBoost (and if needed manually initialize the new module - I was forced to do it on Windows but maybe I did something wrong).

Are you ok with this?

I recently updated to Ubuntu 13.10, where g++ 4.8 is the default compiler. When trying to compile unit tests I got all sort of unused typedef warnings, which was really annoying, and I had to install g++ 4.7 to be able to avoid them. Hopefully what you propose will change this.

BTW, it would be convenient to explain in more detail what you mean by "initialize the new module".
