当我尝试使用/std:c++latest标志在MSVC2015上构建boost时，会出现错误：
boost\algorithm\string\detail\case_conv.hpp(33): error C2143: syntax error: missing ',' before '<'
它指向：
// a tolower functor
template<typename CharT>
struct to_lowerF : public std::unary_function<CharT, CharT>
现在，这似乎是由于N4190所引起的，如此在此处提到：https://www.visualstudio.com/en-us/news/releasenotes/vs2015-update3-vs
/std:c++latest 还控制以下旧特性的删除：N4190“删除auto_ptr，random_shuffle()和旧内容”，P0004R1“删除已弃用的Iostreams别名”，LWG 2385“function::assign allocator argument doesn't make sense”，以及一些非标准功能（std::tr1命名空间，一些仅限于TR1的机制和std::identity结构）。
当使用：
std::string a,b;
return boost::iequals(a,b);
使用 boost::ilexicographical_compare。
这里也提到了：

Stephan T. Lavavej - MSFT Azarien: Removing auto_ptr/etc. will have positive consequences. It will prevent new code from using outdated/complicated/unsafemachinery, and it will reduce confusion among non-expert users. (For example, unnecessary unary_function/binary_function inheritance is common, because many users thought that STL algorithms/containers required this, when in fact only the outdated adapters did.) And auto_ptr in particular is unsafe, because its mutating "copy" constructor silently moves from lvalues.
那么，我该如何使用VC2015的 /std:c++latest 编译boost呢？目前看来，Boost似乎不兼容C++17？
