--- Comment #11 from Frank Heckenbach <f.heckenbach@fh-soft.de> ---
For file modes we have S_IXUSR etc., and most programs don't even need them
very often. So I think making it part of -Wextra seems reasonable these days,
but I'd welcome such a warning either way.

https://thedailywtf.com/articles/padded-mailers recently reminded me that
0-prefixed octals can cause real problems even for experienced programmers.
