These links should take you directly to the Mailing lists http://sourceforge.net/p/sdcc/mailman/sdcc-user/7.2 and the Forums http://sourceforge.net/p/sdcc/discussion/, lists and forums are archived and searchable so if you are lucky someone already had a similar problem. While mails to the lists themselves are delivered promptly their web front end on SourceForge sometimes shows a severe time lag (up to several weeks), if you're seriously using SDCC please consider subscribing to the lists.
