I'm currently playing with gcc-7, which adds a lot of new warnings
(including many false positives). gcc-6 was supposed to have better
warnings than 5, but I didn't find the difference that noticeable. 5
or 6 is probably best at the moment, and if you have at least 4.9
there is no urgent need to upgrade.
