[Boost-users] boost::serialization Bug

Ok, it's not a "bug"... but it's damn annoying to get
compiler warnings from library header. Especially when
those compiler warnings are 1 page long.

Is it possible to please not mention variables that
aren't being used?

This is what I get for a SINGLE warning:

unused parameter ‘t’

Moreover, I normally treat warnings as errors (with -Werror); which is
impossible when a third party library generates warnings.
