'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 problematic Apple configurations, as
- Libc at least through Libc-825.26 (2013-04-09) mishandles it; see, e.g.,
+ Suppress the use of extern inline on problematic Apple configurations.
+ OS X 10.8 and earlier mishandle it; see, e.g.,
<http://lists.gnu.org/archive/html/bug-gnulib/2012-12/msg00023.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>.
Perhaps Apple will fix this some day. */
