/* The _GL_ASYNC_SAFE marker should be attached to functions that are
   signal handlers (for signals other than SIGABRT, SIGPIPE) or can be
   invoked from such signal handlers.  Such functions have some restrictions:
     * All functions that it calls should be marked _GL_ASYNC_SAFE as well,
       or should be listed as async-signal-safe in POSIX
       <https://pubs.opengroup.org/onlinepubs/9699919799/functions/V2_chap02.html#tag_15_04>
       section 2.4.3.  Note that malloc(), sprintf(), and fwrite(), in
       particular, are NOT async-signal-safe.
     * All memory locations (variables and struct fields) that these functions
       access must be marked 'volatile'.  This holds for both read and write
       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:
     * A signal handler should not modify errno (except if it is a handler
       for a fatal signal and ends by raising the same signal again, thus
       provoking the termination of the process).  If it invokes a function
       that may clobber errno, it needs to save and restore the value of
       errno.  */

   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 Sun C 5.12 SunOS_i386 2011/11/16.

   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.
