Here is what I get when I add -ansi to the CXX flags:

This has to do with the fixincludes in sys/types.h from gcc I guess. At least
in this header we see this:

#if  !defined(__STRICT_ANSI__) && !defined(_NO_LONGLONG)
typedef long long               longlong_t;
typedef unsigned long long      u_longlong_t;
#else
/* used to reserve space and generate alignment */
typedef union {
        double  _d;
        int32_t _l[2];
} longlong_t;
typedef union {
        double          _d;
        uint32_t        _l[2];
} u_longlong_t;
#endif  /* __STDC__ - 0 == 0 && !defined(_NO_LONGLONG) */

and for off_t:

#if defined(_LP64) || _FILE_OFFSET_BITS == 32
typedef long            off_t;          /* offsets within files */
#elif _FILE_OFFSET_BITS == 64
typedef longlong_t      off_t;          /* offsets within files */
#endif

#if defined(_LARGEFILE64_SOURCE)
#ifdef _LP64
typedef off_t           off64_t;        /* offsets within files */
#else
typedef longlong_t      off64_t;        /* offsets within files */
#endif
#endif  /* _LARGEFILE64_SOURCE */

So we see that in the 32-bit part with strict ansi longlong is not defined.
This is what I read.

So '#undef sun' in a header (which one?)  seems for me the cheapest/easiest
solution.

Ah, yes, if I did not already mention it, I work on sparc-solaris8 ;) with
multilib build. The -m64 part built fine, btw.
