Well, the SUSv2 spec says:

    If the link named by the new argument exists, it shall be removed
    and old renamed to new. In this case, a link named new shall
    remain visible to other processes throughout the renaming
    operation and refer either to the file referred to by new or old
    before the operation began.

and that's what Linux still uses for its documentation.

This is pretty much moot now:  we use mkstemps if available,
and if not try link before trying rename.
