MSVC 2022 warning using environment

[fsmoke]

When i use environment stuff i'ev got warnings

my code

int main(int argc, char * argv[])
{
	namespace bp = boost::process;

	auto env = boost::this_process::environment();
	bp::environment new_env = env;
	std::vector<std::string> args;
	std::copy(argv + 1, argv + argc, std::back_inserter(args));

	boost::filesystem::path initial = argv[0];
	initial.remove_filename();

	std::vector<std::string> paths_vec;
	boost::split(paths_vec, std::string(start_info::paths), [](char_t c)->bool { return c == ';'; },
		boost::algorithm::token_compress_on);

	std::stringstream rebuilded_paths;
	std::string delim;
	for (auto const & p : paths_vec)
	{
		boost::filesystem::path path = p;
		rebuilded_paths << delim;
		if (!path.is_absolute())
			path = initial / path;

		rebuilded_paths << path.string();
		delim = ";";
	}

	for (auto const & e : new_env)
	{
		if (boost::iequals(e.get_name(), "path"))
		{
			new_env[e.get_name()] += rebuilded_paths.str();
			break;
		}
	}
	
	return bp::system(initial / boost::filesystem::path(start_info::filename), args, new_env);
}

piece of build log:

What about this issue? I don't think that's hard to fix....
