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 the use of extern inline on Apple's platforms,
- as Libc-825.25 (2012-09-19) is incompatible with it; see
+ 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

Perhaps Apple will fix this some day. */
