IMM, how about?

#ifdef __cplusplus
extern "C" {
#endif

#ifndef _Static_assert
#define _Static_assert static_assert
#endif /* _Static_assert */

#ifndef _Alignof
#if defined(_MSC_VER) && !_CRT_HAS_C11
#define _Alignof __alignof
#else
#define _Alignof alignof
#endif
#endif /* _Alignof */

ok

This make a lot error. So I revert it.

May I ask about the error? the modification I apologize for the confusion. My intention is to expand the compatibility of _Static_assert and _Align_of.

As far as I know, if __cplusplus >= 201103L, static_assert is a keyword. if __STDC_VERSION__ >= 201112L, _Static_assert is a keyword. Both __GNUC__ and __clang__ support _Static_assert since version 4.6, and if _MSC_VER >= 1600 supports _Static_assert for both C++ and C.

Therefore, we might need to reorganize to cover all these cases.

I am not familiar with gcc/clang. Seems gcc and clang is ok when use c99. Only msvc must use c11.
