The file H/csGblMtx.h as lines like below that defies (not declares)
static variables and functions.  This gives rise to warnings about
unused static functions

that this was bad C style

static pthread_mutex_t csound_global_lock_ = PTHREAD_MUTEX_INITIALIZER;

static void csound_global_mutex_init_(void)
{
}

static void csound_global_mutex_unlock(void)
{
    pthread_mutex_unlock(&csound_global_lock_);
}

static void csound_global_mutex_lock(void)
{
    pthread_mutex_lock(&csound_global_lock_);
}

static void csound_global_mutex_destroy_(void)
{

That non-op function seems to be called in Threads.c. It looks like an interface that was
 never needed, but left there. Given that the author is not around anymore, we should just
review it and remove if needed.

The global lock seems to be used in cases where two instances of Csound try to load/initialise
some plugins (pmidi only actually).
