The LFS document specifies that unistd.h will contain the definition of _LFS64_LARGEFILE when _LARGEFILE64_SOURCE is defined.  If someone tries to define _LARGEFILE64_SOURCE and there is no unistd.h, which means the system doesn't really have large file support, then it is best at that point for the compilation to throw an error.
