This code was brought in via the recent CPU integration of bug 8050807. (Hi Jerry! - cc'd)

It looks like Solaris has two potential definitions of DIR:

#if defined(__USE_LEGACY_PROTOTYPES__)
/* traditional SVR4 definition */
typedef struct {
        int dd_fd; /* file descriptor */
        int dd_loc; /* offset in block */
        int dd_size; /* amount of valid data */
        char *dd_buf; /* directory block */
} DIR; /* stream data from opendir() */
#else
/* default definition (POSIX conformant) */
typedef struct {
        int d_fd; /* file descriptor */
        int d_loc; /* offset in block */
        int d_size; /* amount of valid data */
        char *d_buf; /* directory block */
} DIR; /* stream data from opendir() */
#endif /* __USE_LEGACY_PROTOTYPES__ */

I can't see what controls __USE_LEGACY_PROTOTYPES__ but presumably either something in Solaris 11.1, or something in SS12u3 is causing this difference.
