including the include directive. Fix minor build issue corrected by converting yypush_buffer_state and yypop_buffer_state to yy_set_buffer_state and a hard-coded 100-deep stack. It was easier to fix it here than to import that support into our flex. The new tools and test hardness remain unsupported at the moment.
