alt Hacker NewsNice, 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

You can use GCC on MS Windows just fine. Installing MSYS2 will also give you a package manager.

That's the nice thing about macros, you can also have the macro generate C++ code using destructors instead of using the cleanup attribute. As long as your other C code is also valid C++ code, it should work.
