    Suppress extern inline with HP-UX cc, as it appears to be broken; see

-   Suppress the use of extern inline on Apple's platforms,

+   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 the use of extern inline on Apple's platforms, as Libc at least
+   through Libc-825.26 (2013-04-09) is incompatible with it; see, e.g.,
    <http://lists.gnu.org/archive/html/bug-gnulib/2012-12/msg00023.html>.
    Perhaps Apple will fix this some day.  */
