[/* Please see the Gnulib manual for how to use these macros.
|
|
|
|
Suppress extern inline with HP-UX cc, as it appears to be broken; see
|
|
<https://lists.gnu.org/r/bug-texinfo/2013-02/msg00030.html>.
|
|
|
|
Suppress extern inline with Sun C in standards-conformance mode, as it
|
|
mishandles inline functions that call each other. 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:
|
|
https://lists.gnu.org/r/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:
|
|
https://lists.gnu.org/r/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 <https://trac.macports.org/ticket/41033>.
|
|
Assume DragonFly and FreeBSD will be similar. */
