Yes i see. I won't fix the code as there are no problems with compilation.
[Book compatibility issues]
Below is the problem with the book. If there is no moving content in the book after moving the first 2 or 3 times, or if the movement is different from the book, the engine does not search. I don't know if this is an engine problem or a winboard problem. After edit game, I ordered the engine to search again.
