That ship has sailed ages ago. There are some things you should just accept about C, or any programming language really. Just because you can do something doesn't mean you should do something. I don't know how many years of experience in C this guy has, but this is a "been there, done that" case for me. I stick to stdint and stdbool today, and even if only half the code/libs I interface with do that, it's already worth the extra _t-typing all the time. Just the fact that they use the i prefix for signed, and s for string has a high chance that his s8 string type gets confused with an 8-bit signed int.

But as you say, it's a personal style, and the author seems to be aware of that:

Because that's by far the most important rule to follow in any language.

I think the rest is less controversial, the 0 vs. NULL thing has been going on forever; I didn't check recently but I'd assume "const somestruct *foo" would still sometimes help out the compiler to optimize vs. the non-const version.
