1471 Suppress extern inline with HP-UX cc, as it appears to be broken; see
1472 <https://lists.gnu.org/r/bug-texinfo/2013-02/msg00030.html>.
1474 Suppress extern inline with Sun C in standards-conformance mode, as it
1475 mishandles inline functions that call each other. E.g., for 'inline void f
1476 (void) { } inline void g (void) { f (); }', c99 incorrectly complains
1477 'reference to static identifier "f" in extern inline function'.
1478 This bug was observed with Sun C 5.12 SunOS_i386 2011/11/16.
1480 Suppress extern inline (with or without __attribute__ ((__gnu_inline__)))
1481 on configurations that mistakenly use 'static inline' to implement
1482 functions or macros in standard C headers like <ctype.h>. For example,
1483 if isdigit is mistakenly implemented via a static inline function,
1484 a program containing an extern inline function that calls isdigit
1485 may not work since the C standard prohibits extern inline functions
1486 from calling static functions (ISO C 99 section 6.7.4.(3).
1487 This bug is known to occur on:
1489 OS X 10.8 and earlier; see:
1490 https://lists.gnu.org/r/bug-gnulib/2012-12/msg00023.html
1493 http://muscles.dragonflybsd.org/bulk/clang-master-potential/20141111_102002/logs/ah-tty-0.3.12.log
1496 https://lists.gnu.org/r/bug-gnulib/2014-07/msg00104.html
1498 OS X 10.9 has a macro __header_inline indicating the bug is fixed for C and
1499 for clang but remains for g++; see <https://trac.macports.org/ticket/41033>.
1500 Assume DragonFly and FreeBSD will be similar.
1502 GCC 4.3 and above with -std=c99 or -std=gnu99 implements ISO C99
1503 inline semantics, unless -fgnu89-inline is used. It defines a macro
1504 __GNUC_STDC_INLINE__ to indicate this situation or a macro
1505 __GNUC_GNU_INLINE__ to indicate the opposite situation.
1506 GCC 4.2 with -std=c99 or -std=gnu99 implements the GNU C inline
1507 semantics but warns, unless -fgnu89-inline is used:
1508 warning: C99 inline functions are not supported; using GNU89
1509 warning: to disable this warning use -fgnu89-inline or the gnu_inline function attribute
1510 It defines a macro __GNUC_GNU_INLINE__ to indicate this situation.
