Only on trying to verbalize the new option, that is, the semantics I expected
this warning to have, did I realize that such a warning is unrealistic to

However, that doesn't change the fact that I find this warning to be misleading
as illustrated by the perceived false negatives in the description of this bug
report at http://llvm.org/bugs/show_bug.cgi?id=16621#c0

Hence, though I don't feel qualified to decide whether this is no longer
relevant, if it is indeed seen as no longer relevant by a qualified person
(such as someone who has made use of this warning in the past), I request this
warning to be removed.

Thank you
