 * @file
 * @author     Ruby developers <ruby-core@ruby-lang.org>
 * @copyright  This  file  is   a  part  of  the   programming  language  Ruby.
 *             Permission  is hereby  granted,  to  either redistribute  and/or
 *             modify this file, provided that  the conditions mentioned in the
 *             file COPYING are met.  Consult the file for details.
 * @warning    Symbols   prefixed  with   either  `RBIMPL`   or  `rbimpl`   are
 *             implementation details.   Don't take  them as canon.  They could
 *             rapidly appear then vanish.  The name (path) of this header file
 *             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_WARNING_PUSH.

 * ### Q&A ###
 *
 * Q: Why all the macros defined in this file are function-like macros?
 *
 * A: Sigh.   This  is  because of  Doxygen.  Its  `SKIP_FUNCTION_MACROS = YES`
 *    configuration setting  requests us  that if  we want  it to  ignore these
 *    macros,  then we  have to  do  two things:  (1)  let them  be defined  as
 *    function-like macros,  and (2) place  them separately in their  own line,
 *    like below:
 *
 *    ```CXX
 *    // NG -- foo's type  considered something like `unsigned int`.
 *    RBIMPL_WARNING_PUSH
 *    int foo(void);
 *    RBIMPL_WARNING_POP
 *
 *    // OK -- the macros are ignored by Doxygen.
 *    RBIMPL_WARNING_PUSH()
 *    int foo(void);
 *    RBIMPL_WARNING_POP()
 *    ```
