This type used to be a hard-coded builtin in R13 and became a type
exported from the 'ets' module (where it clearly belongs) in R14.
If you want your code to be compilable with different Erlang/OTP
versions, the best solution is doing this as part of a configure option
(see e.g. the code of Scalaris for a good example on how to do this).
But I would really recommend to the users of R13 to switch to R14. There
are many good reasons to do that.
