Ruby 2.6.0-preview1 で再現した。

↓のマクロ定義の分岐が #define RUBY_ALIGNOF alignof に行くはずなのに #define RUBY_ALIGNOF _Alignof に行ってしまっているっぽい。 C++ のソースがCのソースとして処理されてしまっている様子。

#ifdef RUBY_ALIGNOF
/* OK, take that definition */
#elif defined(__cplusplus) && (__cplusplus >= 201103L)
#define RUBY_ALIGNOF alignof
#elif defined(__STDC_VERSION__) && (__STDC_VERSION__ >= 201112L)
#define RUBY_ALIGNOF _Alignof
#else
#define RUBY_ALIGNOF(type) ((size_t)offsetof(struct { char f1; type f2; }, f2))
#endif

でマクロを展開してみると、以下のようになっていた。

#define RUBY_ALIGNOF _Alignof
#define __cplusplus 201103L

Rubyのバージョンを変えるとビルドできるのでRubyの方で質問してみた。
