I do not see what is supposed to be resolved by me. I have already stated
which cases are overflow or underflow (those arising from conversion of
preprocessing tokens to tokens) and which are different and should be
under -Wconversion (those arising from conversion of a value from one type
to another), and which of the former should be pedwarns and which
shouldn't. I'll defer to a diagnostics maintainer on whether there should
be separate -Woverflow and -Wunderflow.
