1321      * All memory locations (variables and struct fields) that these functions
1322        access must be marked 'volatile'.  This holds for both read and write
1323        accesses.  Otherwise the compiler might optimize away stores to and
1324        reads from such locations that occur in the program, depending on its
1325        data flow analysis.  For example, when the program contains a loop

1331    Additionally, recall that:
1332      * A signal handler should not modify errno (except if it is a handler
1333        for a fatal signal and ends by raising the same signal again, thus
1334        provoking the termination of the process).  If it invokes a function
1335        that may clobber errno, it needs to save and restore the value of

1552    Suppress extern inline with HP-UX cc, as it appears to be broken; see
1553    <https://lists.gnu.org/r/bug-texinfo/2013-02/msg00030.html>.
1554
1555    Suppress extern inline with Sun C in standards-conformance mode, as it
1556    mishandles inline functions that call each other.  E.g., for 'inline void f
1557    (void) { } inline void g (void) { f (); }', c99 incorrectly complains
1558    'reference to static identifier "f" in extern inline function'.
1559    This bug was observed with Sun C 5.12 SunOS_i386 2011/11/16.
1560
1561    Suppress extern inline (with or without __attribute__ ((__gnu_inline__)))
1562    on configurations that mistakenly use 'static inline' to implement
1563    functions or macros in standard C headers like <ctype.h>.  For example,
1564    if isdigit is mistakenly implemented via a static inline function,
1565    a program containing an extern inline function that calls isdigit
1566    may not work since the C standard prohibits extern inline functions
1567    from calling static functions (ISO C 99 section 6.7.4.(3).
1568    This bug is known to occur on:
1569
1570      OS X 10.8 and earlier; see:
1571      https://lists.gnu.org/r/bug-gnulib/2012-12/msg00023.html
1572
1573      DragonFly; see
1574      http://muscles.dragonflybsd.org/bulk/clang-master-potential/20141111_102002/logs/ah-tty-0.3.12.log
1575
1576      FreeBSD; see:
1577      https://lists.gnu.org/r/bug-gnulib/2014-07/msg00104.html
1578
1579    OS X 10.9 has a macro __header_inline indicating the bug is fixed for C and
1580    for clang but remains for g++; see <https://trac.macports.org/ticket/41033>.
1581    Assume DragonFly and FreeBSD will be similar.
1582
1583    GCC 4.3 and above with -std=c99 or -std=gnu99 implements ISO C99
1584    inline semantics, unless -fgnu89-inline is used.  It defines a macro
1585    __GNUC_STDC_INLINE__ to indicate this situation or a macro
1586    __GNUC_GNU_INLINE__ to indicate the opposite situation.
1587    GCC 4.2 with -std=c99 or -std=gnu99 implements the GNU C inline
1588    semantics but warns, unless -fgnu89-inline is used:
1589      warning: C99 inline functions are not supported; using GNU89
1590      warning: to disable this warning use -fgnu89-inline or the gnu_inline function attribute
1591    It defines a macro __GNUC_GNU_INLINE__ to indicate this situation.
