In PR69864 Manu suggests improving the docs to explain that
-Wnarrowing sometimes produces errors not warnings.
I think the right way to do that is clarify how it interacts with
-std. Specifically that the effect of -Wnarrowing listed first in the
manual *only* applies to C++98 modes, For all later modes (not just
with -std=c++11 as it says now), narrowing conversions produce errors
or warnings by default.
OK for trunk?
OK, thanks.
I suppose the patch is OK as it stands, but I was going to suggest
restructuring it so that it talks about the default behavior first and
what it does with non-default -std= options after that, instead of
vice-versa. Unfortunately I am backlogged on other things right now
and it might take me a day or two before I have time to come up with
some alternate wording. If we are in a rush, go ahead and commit the
existing patch meanwhile, I guess.
I did wonder about that but couldn't come up with wording I liked.
I went ahead and committed it after Jason's OK, but I can take another
look at it next week.
