There is obviously a mismatch between /usr/include/pthread.h and 
/usr/include/sys/types.h on your system.

My version of /usr/include/sys/types.h is

#pragma ident   "@(#)types.h    1.68    02/06/10 SMI

and contains:

typedef struct _pthread_mutex {         /* = mutex_t in synch.h */
        struct {
                uint16_t        __pthread_mutex_flag1;
                uint8_t         __pthread_mutex_flag2;
                uint8_t         __pthread_mutex_ceiling;
                uint16_t        __pthread_mutex_type;
                uint16_t        __pthread_mutex_magic;
        } __pthread_mutex_flags;
        union {
                struct {
                        uint8_t __pthread_mutex_pad[8];
                } __pthread_mutex_lock64;
                struct {
                        uint32_t __pthread_ownerpid;
                        uint32_t __pthread_lockword;
                } __pthread_mutex_lock32;
                upad64_t __pthread_mutex_owner64;
        } __pthread_mutex_lock;
        upad64_t __pthread_mutex_data;
} pthread_mutex_t;


and my version of /usr/include/pthread.h is

#pragma ident   "@(#)pthread.h  1.29    01/07/07 SMI"

and contains (the unfixed macro)

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


What are your versions?

Maybe simply a Solaris 8 bug.
