+   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

+     __GTHREAD_COND_INIT

    All functions returning int should return zero on success or the error
    number.  If the operation is not supported, -1 is returned.
 
    Currently supported threads packages are
-     POSIX threads with -D_PTHREADS
+     TPF threads with -D__tpf__
+     POSIX/Unix98 threads with -D_PTHREADS
+     POSIX/Unix95 threads with -D_PTHREADS95
      DCE threads with -D_DCE_THREADS
      Solaris/UI threads with -D_SOLARIS_THREADS
