Since around Visual Studio 2015 you're fine.

AFAIK the STB headers are on C89 mainly because nothings likes to use VC6 as C IDE.

E.g. if you depend on other C99 features anyway, including stdint.h is fine, also on MSVC.

PS: FWIW I use stdint.h types in the Sokol headers since around 2017 and never heard complaints from users, with the supported compilers being MSVC, GCC and Clang.

Since around Visual Studio 2015 you're fine.

I personally use `_MSC_VER >= 1600`, so it's since Visual Studio 2010 from April 2010. Built-in types like __int32 from before then may be used as well.

Oh, I wasn't sure if that was you :)

Thanks for the advice, I'm a little worried about breaking compatibility with compilers that don't support stdint. But if it's standard for C99 thing then sure.
