Windows TCP/ip programming - #include <winsock2.h> has funny #define on MinGW 64-bit (MSys2) that can confuse beginner developer's.

Hello,
for those, that would using Turbo'Vision for programming TCP/ip Applications under Windows 10/11 64-bit Professional, the current header source release of the Windows WinSock2 32-Bit has a funny, misspelling typo in winsock2.h.
If you open this file on the source tree of MinGW 64, and navigate to the Line: 13, you can find the pre-processor #define WINSOCKAPI
This macro check, if it already taken, if not then it would be defined.
The funny thing on this is, that, if it is not "defined", it will defined.
On the other Hand: you don't need these 5 Lines of code.
So, I pre-process out comment it with #if 0 ... #ifdef
If you don't do this, the MinGW 64 GNU C++ Compiler will strike the compilation of your source files, and abort the running task.
Here are the source header first lines:

#ifndef _WINSOCK2API_
#define _WINSOCK2API_

#include <_mingw_unicode.h>

// added flag by paule32 at 2023-11-18
#if 0
#ifndef _WINSOCKAPI_
#define _WINSOCKAPI_
#else
#warning Please include winsock2.h before windows.h
#endif
#endif
...

I hope this can help other developers, that working under Microsoft Windows Operating Systems.
