Thanks for all this, folks! Steve, can't you just insert the proper defaults
where the struct is defined? I.e. we have in src/core/sys/posix/sys/types.d the
following definition at line 594:

    struct pthread_mutex_t
    {
        c_long                              __sig;
        byte[__PTHREAD_MUTEX_SIZE__]        __opaque;
    }

Changing it to the following makes at least my tests pass:

    struct pthread_mutex_t
    {
        c_long                              __sig = 0x32AAABA7;
        byte[__PTHREAD_MUTEX_SIZE__]        __opaque;
    }
