如何使用 clang 11 编译 Windows API C++ 代码？ [复制]

Question

我刚刚从 llvm 官方网站下载了 llvm-11-win64（我需要使用 clang 而不是 mingw-g++）。我正在尝试编译一个包含 的测试 C++ 文件（头文件取自 mingw64 安装）

// test.cpp
#include <windows.h>

bool WINAPI DllMain(HINSTANCE hModule, DWORD fwdReason, LPVOID reserved)
{
    return TRUE;
}

典型的命令行编译报错，我应该做一些不同的事情吗？

$ clang++ -I "/c/mingw-w64/x86_64-8.1.0-posix-seh-rt_v6-rev0/mingw64/x86_64-w64-mingw32/include/" -c test.cpp

头文件取自 mingw64 安装

Microsoft 提供了与 Clang 一起使用的官方 Windows 标头（如果我没记错的话，Microsoft 不久前开始在 Visual Studio 中提供 Clang）。
