/* This header should define the following symbols under the described

   `-1' means it is never supported.  Undefined means it cannot be
   statically decided.

   _POSIX_V6_ILP32_OFF32   32bit int, long, pointers, and off_t type
   _POSIX_V6_ILP32_OFFBIG  32bit int, long, and pointers and larger off_t type

   _POSIX_V6_LP64_OFF32	   64bit long and pointers and 32bit off_t type
   _POSIX_V6_LPBIG_OFFBIG  64bit long and pointers and large off_t type

   The macros _XBS5_ILP32_OFF32, _XBS5_ILP32_OFFBIG, _XBS5_LP64_OFF32, and
   _XBS5_LPBIG_OFFBIG were used in previous versions of the Unix standard
   and are available only for compatibility.
