OK, I took that as an approval and committed the change as 0b7c27325c7.
Generally speaking, I agree that we definitely should not alter the
source code because of all clang warnings and we don't, we filter out
quite many of them in contrib/filter-clang-warnings.py.
But there is also benefit in limiting the number of cases we filter out
and in this case I thought it was easier to change the source code.
Thank you,
Martin
