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 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. */ +#if (((defined __APPLE__ && defined __MACH__) \ + || defined __DragonFly__ || defined __FreeBSD__) \ + && (defined __header_inline \ + ?
