I added some testing, found/fixed bugs in the gcc backend (initializing constants, division).<BR>
They should be in the automated tests already.<BR>
However don't let this stop you from doing everything/anything you can think of.<BR>
I didn't do all that much and you can save time and get more done by not worrying<BR>
about the duplication.<BR>
Pickles I didn't do anything with at all, so if you really want to avoid/delay duplication,<BR>
start with them.<BR>
