It might be that gcc-testsuite-3.1.tar does not contain the libstdc++
testsuite.  A CVS checkout shows the following:

gromit:/cvs/gcc-3_1-branch/libstdc++-v3:[0]$ grep -r pthread_create .
./testsuite/thread/pthread1.cc:   pthread_create (&prod[i], NULL, produce, static_cast<void*> (tq[i]));
./testsuite/thread/pthread1.cc:   pthread_create (&cons[i], NULL, consume, static_cast<void*> (tq[i]));
./testsuite/thread/pthread2.cc:    pthread_create (&tid[i], NULL, thread_main, 0);
./testsuite/thread/pthread3.cc:    pthread_create (&tid[i], NULL, thread_main, 0);
./testsuite/thread/pthread4.cc:  pthread_create (&prod, NULL, produce, NULL);
./testsuite/thread/pthread4.cc:  pthread_create (&cons, NULL, consume, NULL);
./testsuite/thread/pthread5.cc:      if (pthread_create(&threads[worker], &tattr,
./testsuite/thread/pthread6.cc:    pthread_create (&tid[i], NULL, thread_main, 0);

So, there're 6 pthread tests,
