The easiest way to be 64bit clean is to use _FILEOFFSET_BITS=64. Then off_t is 64bit on all architectures and it is impossible to use 32bit interfaces. However the type off64_t will still not be defined... (On the other hand, when just using _LARGEFILE64_SOURCE it is still easy to mix 32 and 64bit interfaces.)
