compiling glad clang and pedantic causes warning on windows

[mhhany2000]

when compiling glad with clang using the flag -pedantic I get these warnings:

C:/Dev/glad/include\KHR/khrplatform.h:189:9: warning: extension used [-Wlanguage-extension-token]
  189 | typedef __int32                 khronos_int32_t;
      |         ^
C:/Dev/glad/include\KHR/khrplatform.h:190:18: warning: extension used [-Wlanguage-extension-token]
  190 | typedef unsigned __int32        khronos_uint32_t;
      |                  ^
C:/Dev/glad/include\KHR/khrplatform.h:191:9: warning: extension used [-Wlanguage-extension-token]
  191 | typedef __int64                 khronos_int64_t;
      |         ^
C:/Dev/glad/include\KHR/khrplatform.h:192:18: warning: extension used [-Wlanguage-extension-token]
  192 | typedef unsigned __int64        khronos_uint64_t;
      |         

these warnings do not happen on linux.

this seems to be the piece of code where the warning is generated:

#elif defined(_WIN32) && !defined(__SCITECH_SNAP__)

/*
 * Win32
 */
typedef __int32                 khronos_int32_t;
typedef unsigned __int32        khronos_uint32_t;
typedef __int64                 khronos_int64_t;
typedef unsigned __int64        khronos_uint64_t;
#define KHRONOS_SUPPORT_INT64   1
#define KHRONOS_SUPPORT_FLOAT   1

which is only used if _WIN32 is defined, it uses __intN types that are not standard, causing warnings.

How to reproduce:

1. download glad from here
2. add glad.c to your project
3. include glad/glad.h
4. compile with clang and the compiler flag -pedantic

this will cause the warnings mentioned above.

more info:

OS: Windows 11
clang was installed through visual studio installer (C++ Clang Compiler for Windows)
clang --version output:

clang version 18.1.8
Target: x86_64-pc-windows-msvc
Thread model: posix
InstalledDir: C:\Program Files\Microsoft Visual Studio\2022\Community\VC\Tools\Llvm\x64\bin

note sure any of this information is important to the issue but I included them just in case

This is unfortunate, this is coming from a khronos header and is not generated code.

Here is the location: https://github.com/KhronosGroup/EGL-Registry/blob/29c4314e0ef04c730992d295f91b76635019fbba/api/KHR/khrplatform.h#L186-L194

You can try filing an issue in the Khronos repo, I don't think I can (or want to) mess with the official headers on this level in glad.
