Not boost/config.hpp.  This isn't a configuration tool.  More likely 
boost/utility.hpp.

But jump back a bit.  I missed something.  What is wrong with the 
traditional style of coding for unused parameters, and variables?

void foo ( MyClass const& /*c*/ )
{
    // int a ;
    // float b ;
}

Is the issue that a and b are in fact use in some control paths, and so 
can't just be commented out (or outright removed), yet the compiler is 
warning because they aren't used in all control paths?
