通过IDA查看微软编译的loadcfg.obj，在结合源代码可以分析得到 微软在编译时定义了 _CRT_LOADCFG_DISABLE_CET 宏。

因此 增加 _CRT_LOADCFG_DISABLE_CET 宏定义 重新编辑即可。

受影响的工具集，LLVM + 14.25、14.26、14.27

后面又发现这个问题……

__std_init_once_complete、__std_init_once_begin_initialize缺失问题只影响 14.27.29110 工具集。

查证是微软新增了别名，从这里复制了他的aliases文件，重新导入到工程。 https://github.com/microsoft/STL/tree/master/stl/aliases

此外还有一个 stl\xonce2.cpp 文件，对于的clr支持，也添加到了选项中。
