[M3commit] CVS Update: cm3

[Tony Hosking]

On some platforms off_t is not 64 bits.  This from Solaris (see  
off_t==long):

#if defined(_LARGEFILE_SOURCE) || defined(_XPG5)
#ifndef _OFF_T
#define _OFF_T
#if defined(_LP64) || _FILE_OFFSET_BITS == 32
typedef long            off_t;
#else
typedef __longlong_t    off_t;
#endif
#ifdef  _LARGEFILE64_SOURCE
#ifdef _LP64
typedef off_t           off64_t;
#else
typedef __longlong_t    off64_t;
#endif
#endif /* _LARGEFILE64_SOURCE */
#endif /* _OFF_T */
#endif /* _LARGEFILE_SOURCE *
