• 檢查config.log

忽略cl --version/cl -V/cl -qversion之類的錯誤，定位：

• VS解決辦法

原因目前的lib路徑中，找不到kernel32.lib。

搜尋了一下，說是給VS項目加上路徑，項目屬性->配置屬性->VC++目錄->庫目錄，添加二選一：

C:\Program Files (x86)\Microsoft SDKs\Windows\v7.1A\Lib

C:\Program Files (x86)\Microsoft SDKs\Windows\v7.1A\Lib\x64

• JDK11編譯解決辦法1

修改了toolchain_windows.m4，484處增加了一句：
