Hi,
 
I am writing my first boost program and having trouble with the compiler warning against boost 1.44.0.
Is there any way to get rid of those warnings so I can focus on real warnings in my code ?
The gist of warning is :
        boost_1_44_0/include/boost/mpl/aux_/integral_wrapper.hpp:73:96: warning: the result of the conversion is unspecified because '-0x00000000000000001' is outside the range of type 'boost::numeric::udt_builtin_mixture_enum' [-Wconversion]
 
Any help or pointers are appreciated.

====== The following program is a cut down version of my code, just declares sregex
#include <iostream>
#include <boost/xpressive/xpressive.hpp>
 
int main (int _argc, const char** _argv)
{
  std::cout << "argc=" << _argc << " argv=" << _argv << std::endl;
  using namespace boost::xpressive;
  std::string keyword("");
  sregex const re(sregex::compile(keyword, sregex::icase));
}

Just tried this with both gcc 4.2.1 and clang 3.0 using the current Boost (1.48), and it worked fine.
No warnings, even with -Wall

The PO is using -Wconversion

Best,
