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

   statically decided.

   _POSIX_V7_ILP32_OFF32   32bit int, long, pointers, and off_t type

   _POSIX_V7_ILP32_OFFBIG  32bit int, long, and pointers and larger off_t type

   _POSIX_V7_LP64_OFF32	   64bit long and pointers and 32bit off_t type

   _POSIX_V7_LPBIG_OFFBIG  64bit long and pointers and large off_t type

   The macros _POSIX_V6_ILP32_OFF32, _POSIX_V6_ILP32_OFFBIG,

   _POSIX_V6_LP64_OFF32, _POSIX_V6_LPBIG_OFFBIG, _XBS5_ILP32_OFF32,
