I sometimes see Bison related problems in setting up build environments. Therefore to remove Bison from build time dependencies, add `y.tab.c` generated by Bison to the repository. The reduction of dependency at build time also reduces the labor and time for setup and installation in CI. In addition, a path in `#line` directive is converted to a relative path so that its path is constant regardless of development environments.
