Since it was easy enough to cut&paste, I went ahead and answered it
(see below), but the referenced document will be useful in the future...

R5RS Section 3.5 "Proper Tail Recursion"
...
Certain built-in procedures are also required to perform tail
calls. The first argument passed to apply and to call-with-
current-continuation, and the second argument passed to
call-with-values, must be called via a tail call. Similarly,
eval must evaluate its argument as if it were in tail position
within the eval procedure.
