1076    Suppress extern inline with HP-UX cc, as it appears to be broken; see
1077    <https://lists.gnu.org/r/bug-texinfo/2013-02/msg00030.html>.
1078
1079    Suppress extern inline with Sun C in standards-conformance mode, as it
1080    mishandles inline functions that call each other.  E.g., for 'inline void f
1081    (void) { } inline void g (void) { f (); }', c99 incorrectly complains
1082    'reference to static identifier "f" in extern inline function'.
1083    This bug was observed with Oracle Developer Studio 12.6
1084    (Sun C 5.15 SunOS_sparc 2017/05/30).
1085
1086    Suppress extern inline (with or without __attribute__ ((__gnu_inline__)))
1087    on configurations that mistakenly use 'static inline' to implement
1088    functions or macros in standard C headers like <ctype.h>.  For example,
1089    if isdigit is mistakenly implemented via a static inline function,
1090    a program containing an extern inline function that calls isdigit
1091    may not work since the C standard prohibits extern inline functions
1092    from calling static functions (ISO C 99 section 6.7.4.(3).
1093    This bug is known to occur on:
1094
1095      OS X 10.8 and earlier; see:
1096      https://lists.gnu.org/r/bug-gnulib/2012-12/msg00023.html
1097
1098      DragonFly; see
1099      http://muscles.dragonflybsd.org/bulk/clang-master-potential/20141111_102002/logs/ah-tty-0.3.12.log
1100
1101      FreeBSD; see:
1102      https://lists.gnu.org/r/bug-gnulib/2014-07/msg00104.html
1103
1104    OS X 10.9 has a macro __header_inline indicating the bug is fixed for C and
1105    for clang but remains for g++; see <https://trac.macports.org/ticket/41033>.
1106    Assume DragonFly and FreeBSD will be similar.
1107
1108    GCC 4.3 and above with -std=c99 or -std=gnu99 implements ISO C99
1109    inline semantics, unless -fgnu89-inline is used.  It defines a macro
1110    __GNUC_STDC_INLINE__ to indicate this situation or a macro
1111    __GNUC_GNU_INLINE__ to indicate the opposite situation.
1112    GCC 4.2 with -std=c99 or -std=gnu99 implements the GNU C inline
1113    semantics but warns, unless -fgnu89-inline is used:
1114      warning: C99 inline functions are not supported; using GNU89
1115      warning: to disable this warning use -fgnu89-inline or the gnu_inline function attribute
1116    It defines a macro __GNUC_GNU_INLINE__ to indicate this situation.

1552      * All functions that it calls should be marked _GL_ASYNC_SAFE as well,
1553        or should be listed as async-signal-safe in POSIX

1555        section 2.4.3.  Note that malloc(), sprintf(), and fwrite(), in
1556        particular, are NOT async-signal-safe.
1557      * All memory locations (variables and struct fields) that these functions
1558        access must be marked 'volatile'.  This holds for both read and write
1559        accesses.  Otherwise the compiler might optimize away stores to and
1560        reads from such locations that occur in the program, depending on its
1561        data flow analysis.  For example, when the program contains a loop
1562        that is intended to inspect a variable set from within a signal handler
1563            while (!signal_occurred)
1564              ;
1565        the compiler is allowed to transform this into an endless loop if the
1566        variable 'signal_occurred' is not declared 'volatile'.
1567    Additionally, recall that:
1568      * A signal handler should not modify errno (except if it is a handler
1569        for a fatal signal and ends by raising the same signal again, thus
1570        provoking the termination of the process).  If it invokes a function
1571        that may clobber errno, it needs to save and restore the value of
1572        errno.  */
