I don't know what to do about it. My POSIX draft says

int pthread_mutex_init(pthread_mutex_t *restrict mutex, const
pthread_mutexattr_t *restrict attr);

and goes on to specify that 0/NULL for the second argument causes default
attributes to be used.

I know little - if anything - about HPUX 10.20; if you find a solution let
me know, and I'll incorporate it into lwm_pthreads.hpp. Sorry.
