Well, for whatever reason, it's in core.stdc.stdio on Windows, so if you're on Windows, that's what you'd use, whereas on Posix systems, it's in core.sys.posix.fcntl. I would have _thought_ that core.stdc.* would be the same across OSes as its _standard_ C, but for whatever reason, it isn't. Regardless, there's no duplication here on any particular OS, as the definitions in core.stdc.stdio are specific to Windows, whereas the ones in core.sys.posix.fcntl are specific to Posix. - Jonathan M Davis
