Nice, but if the intention is portability my experience has unfortunately been that you pretty much have to stick to C99. MSVC’s C compiler is rough, but pretty much necessary for actual cross platform. I have my own such header which has many, many things like the OP’s. As much as I would find it constantly useful, I don’t have a cleanup utility because of this.

But if you can stay out of MSVC world, awesome! You can do so much with a few preprocessor blocks in a header

MSVC now supports C17.

Does it support C99 with VLAs yet?

It supports C99 minus VLAs. Worth noting that only C99 mandates VLAs. They are optional in C11, C17, and C23.
