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
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));
}
====== The following cmd is used to build it (tried g++ v 4.4.5 and 4.6 with same results)
g++ -ftemplate-depth-128 -O0 -fno-inline -Wall -g -Wconversion -Wno-strict-aliasing -Wextra -Wnon-virtual-dtor -Wno-missing-field-initializers -Wno-array-bounds -Wno-ignored-qualifiers -Wno-parentheses -Wno-strict-aliasing -fPIC -DBOOST_ALL_NO_LIB -I/work/loc1/atddds -I/work/loc1/boost_1_44_0/include -Iinclude -c -o boost_regex_test.o boost_regex_test.cpp
