We have access to a diverse set of systems so I tried to determine
what platforms would require -lpthread because of the recent addition
of the pthread_mutex_* functions for cache locking:
$ cat mutex.c
#include <stdlib.h>
#include <pthread.h>
int
main (void) {
pthread_mutex_t lck;
if (pthread_mutex_init(&lck, 0) != 0)
exit (1);
if (pthread_mutex_lock(&lck) != 0)
exit (1);
if (pthread_mutex_unlock(&lck) != 0)
exit (1);
if (pthread_mutex_destroy(&lck) != 0)
exit (1);
exit (0);
}
