   8  * @warning    Symbols   prefixed   with   either  `RUBY3`   or   `ruby3`   are
   9  *             implementation details.   Don't take  them as canon.  They could
  10  *             rapidly appear then vanish.  The name (path) of this header file
  11  *             is also an  implementation detail.  Do not expect  it to persist
  12  *             at the place it is now.  Developers are free to move it anywhere
  13  *             anytime at will.
  14  * @note       To  ruby-core:  remember  that   this  header  can  be  possibly
  15  *             recursively included  from extension  libraries written  in C++.
  16  *             Do not  expect for  instance `__VA_ARGS__` is  always available.
  17  *             We assume C99  for ruby itself but we don't  assume languages of
  18  *             extension libraries. They could be written in C++98.
  19  * @brief      Signal handling APIs.
