I would much rather see us change the default, if that is really
necessary, than muddy the waters with confusing semantics, semantics
that will change due to minor adjustments to the compiler.
Changing the default may be a good solution for this issue. But when
you describe option #3 as "confusing semantics", I think that means
you still judging this as if it were a proposal for a feature.
Features have semantics, which may be confusing or clear.
If it isn't clear, that is an argument against the feature.
But option #3 is not a feature. It does not have semantics.
To ask whether its semantics are clear or not is to treat it
like a feature, which is a misunderstanding of the basic idea.
There will be other occasions in the future to consider using option
#3, so it is essential for decisions about GCC to be made with clear
understanding of this alternative.
