/* This header should define the following symbols under the described
situations. A value `1' means that the model is always supported,
`-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.
