Writing modern C

For the v4 LCFG client project I’ve been writing lots of C. To get my C knowledge up to scratch I’ve been consulting many books of varying vintages which leads to quite a mixture of coding styles. I’m quite keen to create code which is concerned “good” according to modern coding standards but I also want to ensure it will compile on a wide range of Unix-like systems, that seems to mean right now that the standard to aim for is C99. I recently came across an interesting article titled "How to C (as of 2016)" which gives a good summary of many important topics to consider. I’ve already been following many of the suggestions but there are also quite a few which are totally new to me. I’m not sure I agree with all of them (e.g. not using char) but I shall definitely be applying some of them.
