Check that pthread_t can indeed be passed to Solaris atomic functions, instead of assuming that it can be passed if 0 can be assigned to it. It could be that: * 0 can be assigned, but pthread_t cannot be passed and * 0 cannot be assigned but pthread_t can be passed Better to check what we are interested in, not something else and make assumptions.
