the redefinition of ccl::force-break-in-listener in swank-openmcl.lisp relied on the more-featured-but-not-ansi pre-0.14.1 behavior of invoke-debugger.
the following patch accomplishes the same thing by explicitly creating the condition as the argument to invoke-debugger. it should work for pre-0.14.1 versions, too.
