I'd just use "In IEEE Std 1003.1-2008 (``POSIX.1'') gets() has been
marked as obsolescent". I'd drop the next part as it is already part of
the huge CAVEAT.

I generally agree. gets(3) is somewhat on the edge as it should never
have been used at all, but there are more useful functions that are
useful for dealing with ancient systems, but should be avoided for
non-compat layers.
