* @warning Symbols prefixed with either `RBIMPL` or `rbimpl` are

* is also an implementation detail. Do not expect it to persist
* at the place it is now. Developers are free to move it anywhere
* anytime at will.
* @note To ruby-core: remember that this header can be possibly
* recursively included from extension libraries written in C++.
* Do not expect for instance `__VA_ARGS__` is always available.
* We assume C99 for ruby itself but we don't assume languages of
* extension libraries. They could be written in C++98.
* @brief Defines RBIMPL_COMPILER_IS_Apple.
*
* Apple ships clang. Problem is, its `__clang_major__` etc. are not the
* upstream LLVM version, but XCode's. We have to think Apple's is distinct
* from LLVM's, when it comes to compiler detection business in this header
* file.
