* @warning Symbols prefixed with either `RUBY3` or `ruby3` are
|
|
* implementation details. Don't take them as canon. They could
|
|
* rapidly appear then vanish. The name (path) of this header file
|
|

|
|
* 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 #RUBY3_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.
