Turns out that presently SBCL signals unbound variable warnings only
from SUMMARIZE-COMPILATION-UNIT -- at the end of the compilation unit.
...and ASDF puts a WITH-COMPILATION-UNIT around the entire operation
on system, and so the warnings are still patiently waiting in
SB-C::*UNDEFINED-WARNINGS* to be signalled once ASDF is done.

So writing an :around method on COMPILE-OP to wrap it in a
WITH-COMPILATION-UNIT :OVERRIDE T gets you the same behaviour as
COMPILE-FILE.

...but to get the context in the top-level forms we need to change
SBCL. Not an unfamiliar feat to you, I'd say. ;-) Presumably
NOTE-UNDEFINED-REFERENCE should signal the appropriate warning, and the
end-of-compilation-unit summary could be condenced a bit.

I think that is as good as any. You may want to add :sbcl-hooks-require
to *features* beforehand, though, to get the require-magic.

As far as I am concerned the asdf.texinfo in the cclan repository is
authoritative, but yes, someone (like yours truely) may have at a
clueless moment done things to the version in sbcl repo -- something
to investigate.
