@Gabor
It seems your msys2 installation never was really complete, as grep is already in the 'base' group. https://packages.msys2.org/group/
I suggest running all those commands again one by one, it will only load, what is missing or otherwise update.
Thanks for the hints. I did a complete -Syu and -Su this morning then did everything as you had told me, no success. I'm going to investigate further, as a last resort I may delete the whole msys2 and reinstall everything again.
While I certainly don't understand what I am doing, the result is success. I have installed manually the whole Cygwin base package therefore grep as well. Now CFish compiles perfectly. Thank you both for yor help.
What I still don't understand, although it is not important any more, is why I have this directory in my MSYS2 installation:
Directory of e:\msys64\var\lib\pacman\local\grep-3.0-2
If I could get Cfish to log analysis to disk, I would use it for most of my chess analysis.
I could just make a C interface to the C++ file I use for logging with all of the SF variants, but I won't do that because I feel like it is contrary to the spirit of Cfish (minimalistic C approach using the same algorithms as Stockfish).
Taking ideas is not a vice, it is a virtue. We have another word for this. It is called learning.
But sharing ideas is an even greater virtue. We have another word for this. It is called teaching.

Is CFish now at the same commit level again as SF dev currently?
It is a couple of days behind at the moment.
It seems it is faster than my SFdev compile w/o nnue included. Need to check this more precisely.
The NNUE version should also be faster, in particular if you have an older CPU.
That's what I meant (w/o nnue included = nnue NOT embedded, but used from outside).
Your CFish is a lot faster than SF Devs, compiled by me.
Yours is around 400kn/s, SF dev nnue embedded around 290 and nnue not embedded around 300.
Measured at the date of my previous post from start position, may be depth 25-27.

CFish on my AMD 3970x absolutely rocks.
And AVX2 added so much speed, people will think I am lying if I say it.

If you have a recent AMD and don't want to build it yourself:
