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).

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.

accesses. Otherwise the compiler might optimize away stores to and
reads from such locations that occur in the program, depending on its
data flow analysis. For example, when the program contains a loop
that is intended to inspect a variable set from within a signal handler
while (!signal_occurred)
;
the compiler is allowed to transform this into an endless loop if the
variable 'signal_occurred' is not declared 'volatile'.
Additionally, recall that:

======================================================================
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_NODISCARD
_GL_ATTRIBUTE_PURE
_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.
