我使用vcpkg成功安装了AWS SDK，但在编译我的项目时，我遇到了以下语法错误：'error:'*'token'之前的预期主表达式和第58、86、105和138行的"error:"stdext"尚未声明"。如果这是一个简单的问题，我很抱歉，因为我是C语言和AWS SDK的新手。

我试图按照微软文档中的说明解决：https://learn.microsoft.com/en-us/cpp/standard-library/stdext-namespace?view=msvc-170
但是还没有成功。。。如有任何回应，我们将不胜感激，谢谢。
我刚刚遇到了这个问题，使用非_WIN32代码路径似乎可以工作。
