This is based on the same change recently made in lbmk. A lot of unnecessary patches, and I want to clean them all up. Also, cbmk's /default didn't actually build, whereas lbmk did, which is the primary motive for this rebase. With this change, it should build again. Signed-off-by: Leah Rowe <info@minifree.org>
