The Linux kernel expects a flock64 structure whenever you use OFD locks with fcntl64. Unfortunately, you can currently build a 32-bit program that passes in a struct flock when it calls fcntl64. Only define the F_OFD_* constants when __USE_FILE_OFFSET64 is also defined, so that the build fails in this situation rather than producing a broken binary.
Doesn't this affect legacy POSIX-style locks as well, under very similar circumstances?
