At least GCL doesn't issue a proper warning in case of undeclared free variable.
SBCL, CMUCL and presumably SCL (I believe erroneously) defer such warning
until the end of the compilation unit, which when you don't use ASDF's
deferred-warnings mechanism, gets caught by the (IMHO bogus)
with-compilation-unit
(now in a perform-plan method, previously in operate),
and thus issue a full warning that isn't checked, and the system thus builds
"successfully". I wanted to get rid of that W-C-U,
but that broke many systems in Quicklisp that had such bugs.

I updated the test (with untested expectations for XCL and SCL, that I
can't test anymore).
