   Suppress extern inline with HP-UX cc, as it appears to be broken; see
   <https://lists.gnu.org/r/bug-texinfo/2013-02/msg00030.html>.

   Suppress extern inline with Sun C in standards-conformance mode, as it
   mishandles inline functions that call each other.  E.g., for 'inline void f
   (void) { } inline void g (void) { f (); }', c99 incorrectly complains
   'reference to static identifier "f" in extern inline function'.
   This bug was observed with Oracle Developer Studio 12.6
   (Sun C 5.15 SunOS_sparc 2017/05/30).

   Suppress extern inline (with or without __attribute__ ((__gnu_inline__)))
   on configurations that mistakenly use 'static inline' to implement
   functions or macros in standard C headers like <ctype.h>.  For example,
   if isdigit is mistakenly implemented via a static inline function,
   a program containing an extern inline function that calls isdigit
   may not work since the C standard prohibits extern inline functions
   from calling static functions (ISO C 99 section 6.7.4.(3).
   This bug is known to occur on:

     OS X 10.8 and earlier; see:
     https://lists.gnu.org/r/bug-gnulib/2012-12/msg00023.html

     DragonFly; see
     http://muscles.dragonflybsd.org/bulk/clang-master-potential/20141111_102002/logs/ah-tty-0.3.12.log

     FreeBSD; see:
     https://lists.gnu.org/r/bug-gnulib/2014-07/msg00104.html

   OS X 10.9 has a macro __header_inline indicating the bug is fixed for C and
   for clang but remains for g++; see <https://trac.macports.org/ticket/41033>.
   Assume DragonFly and FreeBSD will be similar.

   GCC 4.3 and above with -std=c99 or -std=gnu99 implements ISO C99
   inline semantics, unless -fgnu89-inline is used.  It defines a macro
   __GNUC_STDC_INLINE__ to indicate this situation or a macro
   __GNUC_GNU_INLINE__ to indicate the opposite situation.
   GCC 4.2 with -std=c99 or -std=gnu99 implements the GNU C inline
   semantics but warns, unless -fgnu89-inline is used:
     warning: C99 inline functions are not supported; using GNU89
     warning: to disable this warning use -fgnu89-inline or the gnu_inline function attribute
   It defines a macro __GNUC_GNU_INLINE__ to indicate this situation.

      So, if we insist on using the 'extern' keyword ('extern CC' idiom):
        * If _GL_ATTRIBUTE_* expands to bracket syntax [[...]]
          in both C and C++, there is one available position:
            - between the function name and the parameter list.
        * If _GL_ATTRIBUTE_* expands to __attribute__((...)) syntax
          in both C and C++, there are several available positions:
            - before the return type,
            - between return type and function name,
            - at the end of the declaration.
        * If _GL_ATTRIBUTE_* expands to bracket syntax [[...]] in C and to
          __attribute__((...)) syntax in C++, there is no available position:
          it would need to come before 'extern' in C but after 'extern "C"'
          in C++.
        * If _GL_ATTRIBUTE_* expands to __attribute__((...)) syntax in C and
          to bracket syntax [[...]] in C++, there is one available position:
            - before the return type.
      Whereas, if we use the 'EXTERN_C_FUNC' idiom, which conditionally
      omits the 'extern' keyword:
        * If _GL_ATTRIBUTE_* expands to bracket syntax [[...]]
          in both C and C++, there are two available positions:
            - before the return type,
            - between the function name and the parameter list.
        * If _GL_ATTRIBUTE_* expands to __attribute__((...)) syntax
          in both C and C++, there are several available positions:
            - before the return type,
            - between return type and function name,
            - at the end of the declaration.
        * If _GL_ATTRIBUTE_* expands to bracket syntax [[...]] in C and to
          __attribute__((...)) syntax in C++, there is one available position:
            - before the return type.
        * If _GL_ATTRIBUTE_* expands to __attribute__((...)) syntax in C and
          to bracket syntax [[...]] in C++, there is one available position:
            - before the return type.
      The best choice is therefore to use the 'EXTERN_C_FUNC' idiom and
      put the attributes before the return type. This works regardless
      to what the _GL_ATTRIBUTE_* macros expand.

/* Attributes in bracket syntax [[...]] vs. attributes in __attribute__((...))
   syntax, in static/inline function definitions.

   There are similar constraints as for function declarations.  However, here,
   we cannot omit the storage-class specifier.  Therefore, the following rule
   applies:
     * The macros
         _GL_ATTRIBUTE_CONST
         _GL_ATTRIBUTE_DEPRECATED
         _GL_ATTRIBUTE_MAYBE_UNUSED

         _GL_ATTRIBUTE_REPRODUCIBLE
         _GL_ATTRIBUTE_UNSEQUENCED
       which may expand to bracket syntax [[...]], must come first, before the
       storage-class specifier.
     * Other _GL_ATTRIBUTE_* macros, that expand to __attribute__((...)) syntax,
       are better placed between the storage-class specifier and the return
       type.
