- 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>.
+ 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:
