 102 The implementation supports the _POSIX_V6_ILP32_OFFBIG programming
 103 environment and the application is being built in the
 104 _POSIX_V6_ILP32_OFFBIG programming environment (see the Shell and
 105 Utilities volume of IEEE Std 1003.1-2001, c99, Programming Environments).

 107 The implementation supports the _POSIX_V6_LP64_OFF64 programming
 108 environment and the application is being built in the
 109 _POSIX_V6_LP64_OFF64 programming environment.
