'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. */
+ 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. */
