bool is already defined in C++.

Only in C++-17, as std::bool. As I mentioned earlier, tbprobe.c is intended to be compiled either as C99 or C++. Either should work, although I have not tested C++17. I have compiled it with MSVC 2019 (C++) and it worked.

I think it would be very helpful if this was hosted on a proper version control system such as Github. I know there was some unofficial hosting there but really it should be authorized by Bob. If that is done it is possible to submit patches via pull request. And there is a place to go for the lates...

tbprobe.c requires a C99 compiler. So for MSVC you need to specify that as the language, or compile that file as C++.

I think Crafty is now using the latest Fathom code, in which case tbcore.h/tbcore.c should be no longer used (these are from the older version before 7-man support was added). Btw your archive only has the .exe - did you mean to include source?

All versions of Crafty are Winboard compatible. I think Fruit was/is only UCI.

Arasan supports both Winboard and UCI (https://www.arasanchess.org).

join waits for the thread to complete, which happens on exit from the thread procedure. So that is an option, if you want to start all the threads when a search starts, and then wait for them to all complete. But my engine (and I think others) has the model that threads are started when the program ...
