I dont think this patch has any ill-effects - But I only tested on Win64/Linux64 Sun Java 6s

Its for http://trac.common-lisp.net/armedbear/attachment/ticket/34 (Ignore the previous patch posted there) The goal of it.. for is for the start leveraging Ahead Of Time compilers like GCJ/EcellisorJET

According to Peter the original use of ".cls" was more for figuring out which files to delete.. not because the classfile format was non-compliant.
