Hi,

I have not yet submitted the bug report, I want to feel extremely confident that I understand the bug so i'm doing some research.  It seems this strategy "removes" extraneous warnings from boost :


instead of 

#include <boost/numeric/conversion/cast.hpp>

change to

#include "hushup/cast.hpp"


then put cast.hpp in hushup directory:

#ifdef __GNUC__
#pragma GCC system_header
#endif

#include <boost/numeric/conversion/cast.hpp>



p00ntang# g++ -I./ -I/usr/local/include -L/usr/local/lib boing.cpp -Werror
p00ntang# ./a.out 
p00ntang#

Perhaps this strategy can be used?

 I'm still checking it out...,


Thanks,
