When I tried to configure GNU make, I receive

...
WARNING: Your system has neither waitpid() nor wait3().
Without one of these, signal handling is unreliable
You should be aware that running GNU make with -j
could result in erratic behavior.
...

What is that supposed to mean ? my spec:

MinGW and MSYS on Windows 10 (64 bit all)

shell has system mingw64 - environment variable MSYSTEM="MINGW64" - and path to its bin first, before msys/usr/bin, when work's being done

Any sincere useful help is really thanked and appreciated

The make still works right? -j is an option for parallel build, for example -j2 will use two cpu cores to build your program instead of just one(-j1), this makes this much faster to compile huge programs, but not all software supports it.

So if make still works, just make sure you build your software with -j1
