Treating warnings as errors caused Bison to exit earlier than needed, making it hide warnings that would have been printed had -Werror not been set. Also, fix a bug that caused some context information of errors to not be shown. * src/complain.c (complaint_issued): Rename as... (complaint_status): This, and change its type from boolean to * src/complain.h (err_status): This, new enumeration. * src/main.c (main): Adjust (only finish early if an actual complaint was risen, not a mere warning treated an error). * src/reader.c: Adjust.
