Probably largefile support if I had to make a guess...  See below.

Quite correct... I wasn't very clear.

Line 148 is:

extern int setrlimit(int, const struct rlimit *);

Here is the relevant portion of resource.h on solaris 2.6:

/*************************************************************************/
#if defined(__STDC__)

extern int setrlimit(int, const struct rlimit *);    /* ** line 148 ** */
extern int getrlimit(int, struct rlimit *);

/* transitional large file interfaces */
#if     defined(_LARGEFILE64_SOURCE) && !((_FILE_OFFSET_BITS == 64) && \
            !defined(__PRAGMA_REDEFINE_EXTNAME))
extern int setrlimit64(int, const struct rlimit64 *);
extern int getrlimit64(int, struct rlimit64 *);
#endif  /* _LARGEFILE64_SOURCE... */

extern int getpriority(int, id_t);
extern int setpriority(int, id_t, int);
extern int getrusage(int, struct rusage *);

#else   /* __STDC__ */

extern int getrlimit();
extern int setrlimit();

/* transitional large file interfaces */
#if     defined(_LARGEFILE64_SOURCE) && !((_FILE_OFFSET_BITS == 64) && \
            !defined(__PRAGMA_REDEFINE_EXTNAME))
extern int setrlimit64();
extern int getrlimit64();
#endif  /* _LARGEFILE64_SOURCE... */

extern int getpriority();
extern int setpriority();
extern int getrusage();

#endif  /* __STDC__ */
/*************************************************************************/

And here's what it looks like in Solaris 8:

/*************************************************************************/
#if defined(__STDC__)

extern int setrlimit(int, const struct rlimit *);
extern int getrlimit(int, struct rlimit *);

/* transitional large file interfaces */
#if     defined(_LARGEFILE64_SOURCE) && !((_FILE_OFFSET_BITS == 64) && \
            !defined(__PRAGMA_REDEFINE_EXTNAME))
extern int setrlimit64(int, const struct rlimit64 *);
extern int getrlimit64(int, struct rlimit64 *);
#endif  /* _LARGEFILE64_SOURCE... */

extern int getpriority(int, id_t);
extern int setpriority(int, id_t, int);
extern int getrusage(int, struct rusage *);

#else   /* __STDC__ */

extern int getrlimit();
extern int setrlimit();

/* transitional large file interfaces */
#if     defined(_LARGEFILE64_SOURCE) && !((_FILE_OFFSET_BITS == 64) && \
            !defined(__PRAGMA_REDEFINE_EXTNAME))
extern int setrlimit64();
extern int getrlimit64();
#endif  /* _LARGEFILE64_SOURCE... */

extern  int getpriority();
extern  int setpriority();
extern  int getrusage();

#endif  /* __STDC__ */
/*************************************************************************/

(I can get solaris 7's version too)

If I had to shoot into the dark about what's causing this, it'd be the
migration path Sun took from 32 bit to 64 bit.  2.6 was the first,
partially 64 bit OS sun made (IIRC).  It only did a 64 bit file system,
leaving the rest of the kernel relativly unharmed.  Solaris 7 was fully 64
bit.

If I can help with things, let me know.
