Subject: [PATCH] include <cstdint> explicitly
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Prior to gcc-13 various C++ headers in gcc included `<cstdint>` even
though it was not strictly necessary; this results in the compiler
having to parse unnecessary code and thus slows down compilation for
everyone. Those unnecessary #includes of `<cstdint>` have been removed
and applications which need the `<cstdint>` header file need to
explicitly include it.
Without the patch, when compiling with gcc-13 you will get this error:
```
