    '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.
-   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:
+
+     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>.
