boost vc6 使用filesystem时，文件err_code.hpp编译通不过（使用模板） 敬请各位高手能不吝赐教！

问题如题目。补充一下：最近在使用boost，使用了filesystem类库。
引用头文件：#include "boost/filesystem/operations.hpp"
#include "boost/filesystem/path.hpp"

源代码：//先测试使用filesystem有没有问题，程序主体未完成
namespace fs = boost::filesystem;
// get the path
if (strPath.size() < 2)
{
return;
}

fs::path full_path(fs::initial_path());
full_path = fs::system_complete(fs::current_path(strPath,fs::native));

unsigned long file_count = 0;
unsigned long dir_count = 0;
unsigned long err_count = 0;

if (!fs::exists( full_path ))
{
//TODO
}
但在编译时，在err_code.hpp文件中出现了大量错误：

我使用的是vc6，敬请各位高手能不吝赐教，解决这个问题。

谢谢大家 是编译器的问题 刚刚换了vs2005 通过了

[Treazy]

错误这么多，一个一个改吧

[czxstarhust]

err_code.hpp 是boost自带的system库的文件，我估计是vc编译器的问题，但不确定。

[taodm]

VC6，建议升级编译器，或者不考虑使用boost。

[珍惜生命远离CPP]

看看是什么代码引起的，通常你得升级编译器。
