Re: RFC: -Wall by default

Well there are three possibilities


a) fix the false positives, at the possible expense of introducing
new false negatives, but most of these warnings are very far from
sound anyway (they do not guarantee that code not raising the warning
is free from the problem involved).

b) remove from -Wstandard

c) leave in -Wstandard and live with the false positives

I am saying I prefer these alternatives in the order given above.
I suspect you agree with this ordering?

I use -Wstandard here just as a label for whatever gets turned
on by default if a change is made. Whether the new switch with
this name is introduced is an orthogonal issue.

  (certainly not an attitude that is
taken with -Wall, if I am wrong, I have hundreds of bugs to
report :-)) Yes, occasionally you get a case that you end up
considering SO obscure that you violate this rule, but it is
rare.

-Wall, despite the name, does not turn on all warnings.

Yes, I know, what's that got to do with the comment above
