In the Bug Justice minigame code, clang warns of bitwise shifts of a negative value, which are undefined behavior in C++:

engines/bbvs/minigames/bbant.cpp
591: obj->yIncr = (-1 << 16);
733: obj->x < (-10 << 16) || obj->x > (330 << 16) ||
734: obj->y < (-10 << 16) || obj->y > (250 << 16);
934: obj->yIncr = (-4 << 16);
