Deferred compilation logic to date works as follow: if an elc is being loaded, is lexical and the corresponding source is found, then an async compilation is queued. No file date is taken in account. Is it possible that the old eln is still being loaded because load-prefer-newer is nil? Thanks for testing it, ciao! Andrea -- akrl@sdf.org
