- * @file
- * @author     Ruby developers <[email protected]>
- * @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.
- * @cond       INTERNAL_MACRO

- * ### Q&A ###
- *
- * Q: Why all the macros defined in this file are function-like macros?
- *
- * A: Sigh.   This  is  because of  Doxgen.   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()
- *    ```
