seeing some of the latest commits about fixing compiler warnings I took
a look at the buildfarm to see if there are any interesting ones there
(in total we have a thousends of warnings on the buildfarm but most of
those are from very noisy compilers).

so in case anybody is interested those are a selection of the ones that
at least look somewhat interesting(duplicates mostly removed, windows
ignored):
