Semantic token for _countof macro specifically is incorrect about vscode-cpptools

[Colengms]

Hi @leidegre I can repro this issue with 1.20.5, but it appears to be fixed in the latest prerelease (1.21.0). Closing as fixed.

Could you provide the code snippet that is causing the issue?

Does this issue persist when all other extension except for C/C++ are disabled?

If I try to goto the definition of the _countof macro I end up here, in vcruntime.h. __crt_countof happens to be the same length as the incorrectly colored tokens, so it is somehow mistaking _countof for __crt_countof (it's five additional characters that gets colored incorrectly).

#ifdef __cplusplus
    extern "C++"
    {
        template <typename _CountofType, size_t _SizeOfArray>
        char (*__countof_helper(_UNALIGNED _CountofType (&_Array)[_SizeOfArray]))[_SizeOfArray];

        #define __crt_countof(_Array) (sizeof(*__countof_helper(_Array)) + 0)
    }
#else
    #define __crt_countof(_Array) (sizeof(_Array) / sizeof(_Array[0]))
#endif

The actual definition of _countof is in stdlib.h and looks like this

#ifndef _countof
    #define _countof __crt_countof
#endif

This happens with all other extensions disabled.
