If an implementation provides integer types with width 64 that meet
these requirements, then the following types are required: int64_t uint64_t

In particular, this will be the case if any of the following are true:

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

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

The implementation supports the _POSIX_V6_LPBIG_OFFBIG programming
environment and the application is being built in the
_POSIX_V6_LPBIG_OFFBIG programming environment.
