-/* If this file is compiled with threads support, it must
-       #define __GTHREADS 1
-   to indicate that threads support is present.  Also it has define
-   function
-     int __gthread_active_p ()
-   that returns 1 if thread system is active, 0 if not.
-
-   The threads interface must define the following types:
-     __gthread_key_t
-     __gthread_once_t
-     __gthread_mutex_t
-     __gthread_recursive_mutex_t
-
-   The threads interface must define the following macros:
-
-     __GTHREAD_ONCE_INIT
-     		to initialize __gthread_once_t
-     __GTHREAD_MUTEX_INIT
-     		to initialize __gthread_mutex_t to get a fast
-		non-recursive mutex.
-     __GTHREAD_MUTEX_INIT_FUNCTION
-     		some systems can't initialize a mutex without a
-		function call.  On such systems, define this to a
-		function which looks like this:
-		  void __GTHREAD_MUTEX_INIT_FUNCTION (__gthread_mutex_t *)
-		Don't define __GTHREAD_MUTEX_INIT in this case
-     __GTHREAD_RECURSIVE_MUTEX_INIT
-     __GTHREAD_RECURSIVE_MUTEX_INIT_FUNCTION
-     		as above, but for a recursive mutex.
-
-   The threads interface must define the following static functions:
-
-     int __gthread_once (__gthread_once_t *once, void (*func) ())
-
-     int __gthread_key_create (__gthread_key_t *keyp, void (*dtor) (void *))
-     int __gthread_key_delete (__gthread_key_t key)
-
-     void *__gthread_getspecific (__gthread_key_t key)
-     int __gthread_setspecific (__gthread_key_t key, const void *ptr)
-
-     int __gthread_mutex_destroy (__gthread_mutex_t *mutex);
-
-     int __gthread_mutex_lock (__gthread_mutex_t *mutex);
-     int __gthread_mutex_trylock (__gthread_mutex_t *mutex);
-     int __gthread_mutex_unlock (__gthread_mutex_t *mutex);
-
-     int __gthread_recursive_mutex_lock (__gthread_recursive_mutex_t *mutex);
-     int __gthread_recursive_mutex_trylock (__gthread_recursive_mutex_t *mutex);
-     int __gthread_recursive_mutex_unlock (__gthread_recursive_mutex_t *mutex);
-
-   The following are supported in POSIX threads only. They are required to
-   fix a deadlock in static initialization inside libsupc++. The header file
-   gthr-posix.h defines a symbol __GTHREAD_HAS_COND to signify that these extra
-   features are supported.
-
-   Types:
-     __gthread_cond_t
-
-   Macros:
-     __GTHREAD_COND_INIT
-     __GTHREAD_COND_INIT_FUNCTION
-
-   Interface:
-     int __gthread_cond_broadcast (__gthread_cond_t *cond);
-     int __gthread_cond_wait (__gthread_cond_t *cond, __gthread_mutex_t *mutex);
-     int __gthread_cond_wait_recursive (__gthread_cond_t *cond,
-					__gthread_recursive_mutex_t *mutex);
-
-   All functions returning int should return zero on success or the error
-   number.  If the operation is not supported, -1 is returned.
-
-   If the following are also defined, you should
-     #define __GTHREADS_CXX0X 1
-   to enable the c++0x thread library.
-
-   Types:
-     __gthread_t
-     __gthread_time_t
-
-   Interface:
-     int __gthread_create (__gthread_t *thread, void *(*func) (void*),
-                           void *args);
-     int __gthread_join (__gthread_t thread, void **value_ptr);
-     int __gthread_detach (__gthread_t thread);
-     int __gthread_equal (__gthread_t t1, __gthread_t t2);
-     __gthread_t __gthread_self (void);
-     int __gthread_yield (void);
-
-     int __gthread_mutex_timedlock (__gthread_mutex_t *m,
-                                    const __gthread_time_t *abs_timeout);
-     int __gthread_recursive_mutex_timedlock (__gthread_recursive_mutex_t *m,
-                                          const __gthread_time_t *abs_time);
-
-     int __gthread_cond_signal (__gthread_cond_t *cond);
-     int __gthread_cond_timedwait (__gthread_cond_t *cond,
-                                   __gthread_mutex_t *mutex,
-                                   const __gthread_time_t *abs_timeout);
-     int __gthread_cond_timedwait_recursive (__gthread_cond_t *cond,
-                                             __gthread_recursive_mutex_t *mutex,
-                                             const __gthread_time_t *abs_time)
-
-   Currently supported threads packages are
-     TPF threads with -D__tpf__
-     POSIX/Unix98 threads with -D_PTHREADS
-     DCE threads with -D_DCE_THREADS
