These should work better under linux etc. If not, please report in the SourceForge bugtracker for the faac project. Not much is new, just some small fixes and third party committed Blackfin support. Some more work on this Blackfin support will probably be done soon.
Other news is the little change in the copyright header and the readme of FAAD2. Apparantly a lot of projects were troubled about the extra requirement that the old header asked for.
