Yup.  The function is used elsewhere in macroexp, too, but there it's
guarded by an fboundp.

I think we should probably consider moving that function (and the
variables defined by it) somewhere else (perhaps a new file), because it
seems the requiring going on there is sort of in an odd direction.
