Wouldn't printing the string out require *standard-output*?

This is the results I got from the various ways of printing things out.

:ecl (princ "foo")
<99>^A
:ecl (format t "foo")
<99>^A
:ecl (msg "foo") ; MSG defined in if_ecl.c
^U^A

Yup, exactly the same results there.  However, I did have to change
make_cons() into CONS() as make_cons() was #if 0'd out in both ECL
0.9j and 0.9i.
