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