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>.
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.
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:
1570 OS X 10.8 and earlier; see:
1571 https://lists.gnu.org/r/bug-gnulib/2012-12/msg00023.html
1574 http://muscles.dragonflybsd.org/bulk/clang-master-potential/20141111_102002/logs/ah-tty-0.3.12.log
1577 https://lists.gnu.org/r/bug-gnulib/2014-07/msg00104.html
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.
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.
