Yep. There have been reports of build failures when using CCL as host,
due to full warnings from forward references to type specifiers.
For example, CCL's COMPILE-FILE (1.5-r13651) returns a tertiary value of T for
(bar (error "missing argument") :type bar))
(defun bar-foo (bar)
(declare (type bar bar))
(make-foo :bar bar))
if type BAR is not yet defined. The offending form appears to be the
declaration in BAR-FOO. (The suboptimality of code such as this is not
in any dispute.)
The question is if CCL considers such forward references worth a full
warning (and hence COMPILE-FILE returning a non-NIL tertiary value),
or if this is unintentional?
If the warning is here to stay, then we obviously need to adjust the
SBCL bootstrap to suit -- but if not, I would let the sleeping
bootstrap lie just for now...
