Re: [glibc PATCH] fcntl: put F_OFD_* constants under #ifdef __USE_FILE_OFFSET64

So yeah, I think what I proposed before would probably be fine. But now
that Michael pushed the issue, it's dawned on me that we may be able to
get away with supporting it better if we turn the compatability
mechanism on its head and use F_OFD_*32 constants in the non-LFS case.


That's rather confusing to programmers, though.

We then have:

F_OFD_SETLK     always 64-bit
F_SETLK         32-bit or 64-bit
F_SETLK64       always 64-bit (not recommended)
F_OFD_SETLK32   always 32-bit

Until we make fcntl type-safe, this doesn't really fly, I'm afraid.
