With some experimentation, I have discovered that the following is
the correct definition of PTHREAD_MUTEX_INITIALIZER on
Sparc-Solaris-2.7:

#define PTHREAD_MUTEX_INITIALIZER {{{0},0},{{{0}}},{0}}

Currently I put this in bits/stl_threads.h immediately after the
#include <pthread.h>

Is this the correct place, or should it go somewhere else?
