latest build of abseil-cpp failed with elaborated-type-specifier for a scoped enum must not use the ‘class’ keyword

Build fail
Build fail with elaborated-type-specifier for a scoped enum must not use the ‘class’ keyword in 3rd party code in
build/_deps/grpc-src/third_party/abseil-cpp/absl/strings/internal/str_format/extension.h:34

Reason is a missing include of #include <cstdint> before.

#include <cstdint>

#include "absl/base/config.h"
#include "absl/base/port.h"
#include "absl/meta/type_traits.h"
#include "absl/strings/internal/str_format/output.h"
#include "absl/strings/string_view.h"

namespace absl {
ABSL_NAMESPACE_BEGIN

enum class FormatConversionChar : uint8_t;
enum class FormatConversionCharSet : uint64_t;

I was able to complete the build (a few warnings though).
I wonder whether the include statement could be done outside of the fetched as a cmake statement.

Hi Jens, Thanks for reporting.
I will have a look, maybe we could simply step up the gRPC version of the dependency, as I am sure this problem would affect upstream code too.

reproduced with gcc (GCC) 13.2.1 20231011 (Red Hat 13.2.1-4)

I added PR #152 to step up gRPC version, which should fix this issue.

@ja66 : would you be willing to review this PR? (I somehow cannot request an official review from you, probably because you are not in the correct ORG)
