- 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>.
- Assume DragonFly and FreeBSD will be similar. */

+ 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. */
