How about compiler warnings (and errors)? When I compile on Windows,
there are a boatload of orange-yellow warnings. Some are about using a
deprecated featured; some about dodgy casts; some (I presume) about
other things. Should 'no warnings' be a goal?
I believe you once fixed some, but new commits added more. Could 'no
additional warnings' be a CI requirement for merging? I expect that a
new "How to avoid compiler warnings on Windows" section of the devguide
would be needed.
