13 | Suppress extern inline with HP-UX cc, as it appears to be broken; see | ||
14 | <http://lists.gnu.org/archive/html/bug-texinfo/2013-02/msg00030.html>. | ||
15 | |||
16 | Suppress extern inline with Sun C in standards-conformance mode, as it | ||
17 | mishandles inline functions that call each other. E.g., for 'inline void f | ||
18 | (void) { } inline void g (void) { f (); }', c99 incorrectly complains | ||
19 | 'reference to static identifier "f" in extern inline function'. | ||
20 | This bug was observed with Sun C 5.12 SunOS_i386 2011/11/16. | ||
21 | |||
22 | Suppress extern inline (with or without __attribute__ ((__gnu_inline__))) | ||
23 | on configurations that mistakenly use 'static inline' to implement | ||
24 | functions or macros in standard C headers like <ctype.h>. For example, | ||
25 | if isdigit is mistakenly implemented via a static inline function, | ||
26 | a program containing an extern inline function that calls isdigit | ||
27 | may not work since the C standard prohibits extern inline functions | ||
28 | from calling static functions. This bug is known to occur on: | ||
29 | |||
30 | OS X 10.8 and earlier; see: | ||

36 | FreeBSD; see: | ||
37 | http://lists.gnu.org/archive/html/bug-gnulib/2014-07/msg00104.html | ||
38 | |||
39 | OS X 10.9 has a macro __header_inline indicating the bug is fixed for C and | ||
40 | for clang but remains for g++; see <http://trac.macports.org/ticket/41033>. | ||

22 | dnl Sets the variables LIBMULTITHREAD and LTLIBMULTITHREAD similarly, for | ||
23 | dnl programs that really need multithread functionality. The difference | ||
24 | dnl between LIBTHREAD and LIBMULTITHREAD is that on platforms supporting weak | ||
25 | dnl symbols, typically LIBTHREAD is empty whereas LIBMULTITHREAD is not. | ||
