vs中也没有提示msvc需要升级，vs用的是visual studio 2019版本

已采纳

确认了一下问题，可能是 msvc 版本更新之后对 ThreadLocal 的支持收紧了。用 mingw 运行吧。msvc 本来也不是什么正经 C 编译器。

不过也可以 cmake 里面替换一下标准版本的设置，msvc 用 c99：

if (MSVC)
    # MSVC 现在对 C11 做了部分支持，反而导致 tinycthread 无法通过编译，因此我们还是以 C99 的模式运行本章示例
    set(CMAKE_C_STANDARD 99)
else()
    set(CMAKE_C_STANDARD 11)
endif ()

课程源码已经更新。
