  40 /* If this file is compiled with threads support, it must
  41        #define __GTHREADS 1
  42    to indicate that threads support is present.  Also it has define
  43    function
  44      int __gthread_active_p ()
  45    that returns 1 if thread system is active, 0 if not.
  46
  47    The threads interface must define the following types:
  48      __gthread_key_t
  49      __gthread_once_t
  50      __gthread_mutex_t
  51      __gthread_recursive_mutex_t
  52
  53    The threads interface must define the following macros:
  54
  55      __GTHREAD_ONCE_INIT
  56                 to initialize __gthread_once_t
  57      __GTHREAD_MUTEX_INIT
  58                 to initialize __gthread_mutex_t to get a fast
  59                 non-recursive mutex.
  60      __GTHREAD_MUTEX_INIT_FUNCTION
  61                 some systems can't initialize a mutex without a
  62                 function call.  On such systems, define this to a
  63                 function which looks like this:
  64                   void __GTHREAD_MUTEX_INIT_FUNCTION (__gthread_mutex_t *)
  65                 Don't define __GTHREAD_MUTEX_INIT in this case
  66      __GTHREAD_RECURSIVE_MUTEX_INIT
  67      __GTHREAD_RECURSIVE_MUTEX_INIT_FUNCTION
  68                 as above, but for a recursive mutex.
  69
  70    The threads interface must define the following static functions:
  71
  72      int __gthread_once (__gthread_once_t *once, void (*func) ())
  73
  74      int __gthread_key_create (__gthread_key_t *keyp, void (*dtor) (void *))
  75      int __gthread_key_delete (__gthread_key_t key)
  76
  77      void *__gthread_getspecific (__gthread_key_t key)
  78      int __gthread_setspecific (__gthread_key_t key, const void *ptr)
  79
  80      int __gthread_mutex_lock (__gthread_mutex_t *mutex);
  81      int __gthread_mutex_trylock (__gthread_mutex_t *mutex);
  82      int __gthread_mutex_unlock (__gthread_mutex_t *mutex);
  83
  84      int __gthread_recursive_mutex_lock (__gthread_recursive_mutex_t *mutex);
  85      int __gthread_recursive_mutex_trylock (__gthread_recursive_mutex_t *mutex);
  86      int __gthread_recursive_mutex_unlock (__gthread_recursive_mutex_t *mutex);
  87
  88    All functions returning int should return zero on success or the error
  89    number.  If the operation is not supported, -1 is returned.
  90
  91    Currently supported threads packages are
  92      TPF threads with -D__tpf__
  93      POSIX/Unix98 threads with -D_PTHREADS
  94      POSIX/Unix95 threads with -D_PTHREADS95
  95      DCE threads with -D_DCE_THREADS
  96      Solaris/UI threads with -D_SOLARIS_THREADS
