注意： mingw32 不支持wWinMain作為程序入口，需要將wWinMain改為WinMain 。

One thing to note is that Visual C++ supports a “wWinMain” entry point where the “lpCmdLine” parameter is a “LPWSTR”. You would typically use the “_tWinMain” preprocessor definition for your entry point and declare “LPTSTR lpCmdLine” so that you can easily support both ANSI and Unicode builds. However, the MinGW CRT startup library does not support wWinMain, so you’ll have to stick with the standard “WinMain” and use “GetCommandLine()” if you need to access command line arguments.

Use WinMain instead. This program doesn't use pCmdLine value, so it should compile when you change wWinMain to WinMain and PWSTR pCmdLine to PSTR pCmdLine.
