Yeah, cross my mind too. I'd like to understand why it was
removed first. (I don't know whether it used to be in -Wall, or
default, or enabled along some other -Wfoo option.)
I found these:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=7302
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=15214
but those fixed false positives. I think that would
have supported enabling by default. Sounds like something
else might have been identified.
Thanks,
