Please include cstdint for gcc13

[toge]

There are several compilation errors with gcc 13. You need to include cstdint and add the std:: prefix as described in the error message.

This fix is within the scope of the C++ standard and should not affect other compilers.

Thanks for the fix. My only issue with this PR is that I am not a fan of prefixing simple basic types with std::. I would work without the prefix, wouldn't it?

@toge : can you check if changing g++/gcc13 to version 14 in the GH workflow already works? I think Ubuntu 24.04 ships GCC 14 or at least has install options for it.

@Bouncner Sorry for not responding to your reply. I haven't had a lot of time recently, but I will try to respond to the points you pointed out within the next couple of weeks.

@Bouncner Sorry for the delay. I changed this PR to include stdint.h instead of cstdint to avoid compilation errors with gcc13 and later without std:: prefix.

This modification will allow compiling with gcc13 without using std:: and without affecting the previous gcc.

Could you review it again?

I checked sql-parser works fine on gcc14 without this PR on Fedora Linux 40. This PR seems to be only for gcc 13 now.

Hi @toge, I would go ahead and merge the main branch, but since you are working on a fork, I am not able to.

Are you still interested in getting this PR landed? If you don't have the time, I would take it from here.

@Bouncner Sorry for suspending this PR.

Please go a head. I am happy if this library works on much more environment.

Oh ... did not know I can resolve conflicts on my own here.
