I don't understand what you mean here. You said you never know what is enabled by -Wall or -Wextra, I pointed out the manual explains it. It is quite rare for a -W option to be moved in or out of the -Wall set, so it doesn't vary between versions. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=44210
