1286 Suppress extern inline with HP-UX cc, as it appears to be broken; see
1287 <https://lists.gnu.org/r/bug-texinfo/2013-02/msg00030.html>.
1289 Suppress extern inline with Sun C in standards-conformance mode, as it
1290 mishandles inline functions that call each other. E.g., for 'inline void f
1291 (void) { } inline void g (void) { f (); }', c99 incorrectly complains
1292 'reference to static identifier "f" in extern inline function'.
1293 This bug was observed with Sun C 5.12 SunOS_i386 2011/11/16.
1295 Suppress extern inline (with or without __attribute__ ((__gnu_inline__)))
1296 on configurations that mistakenly use 'static inline' to implement
1297 functions or macros in standard C headers like <ctype.h>. For example,
1298 if isdigit is mistakenly implemented via a static inline function,
1299 a program containing an extern inline function that calls isdigit
1300 may not work since the C standard prohibits extern inline functions
1301 from calling static functions. This bug is known to occur on:
1303 OS X 10.8 and earlier; see:
1304 https://lists.gnu.org/r/bug-gnulib/2012-12/msg00023.html
1307 http://muscles.dragonflybsd.org/bulk/bleeding-edge-potential/latest-per-pkg/ah-tty-0.3.12.log
1310 https://lists.gnu.org/r/bug-gnulib/2014-07/msg00104.html
1312 OS X 10.9 has a macro __header_inline indicating the bug is fixed for C and
1313 for clang but remains for g++; see <https://trac.macports.org/ticket/41033>.
