I think you're seeing a difference between v371 and v4.1.3, as opposed
to between Windows ad Mac OS X. There are definitely some differences
between the versions, even within the "Pretty Big" language.

But `identity' and `compose' are defined in "Pretty Big" for both v371
and v4.1.3, so I'm still a little puzzled about the specific mismatch.
